Overview of our technologies

Music, home cinema and gaming sound without compromise

The systems' two premium tower speakers deliver gorgeous stereo playback with music. The same high-end sound accompanies home cinema and gaming with the addition of a centre, surround speakers and powerful subwoofer. All components are perfectly aligned and share the same driver technology for a harmonious listening experience.

Teufel home cinema loudspeaker Theater 500 Heimkino 5.1 Surround
DEVELOPED IN BERLIN
The Theater 500 was designed for highly transparent playback, making it the perfect companion for movie sound, gaming and music. Unlike systems engineered to quickly impress and just as quickly fatigue the ears, the Theater 500 produces no unnaturally elevated bass, no sharp and shrill treble. The following features elevate the Theater 500 above standard stereo speakers:

Time Alignment
A system for correcting time alignment enables a better, more precise positioning of vocals and instruments within the stereo panorama.

Constant Directivity Concept
A newly designed waveguide and phase plug ensure broad and even sound dispersion.

Damping chamber
A sound-damping chamber specially designed according to the Helmholtz Resonance principle ensures a clean sound. This effectively eliminates the formation of standing waves and unwanted resonances within the enclosure.

Downfiring bass reflex system
A bass reflex system prevents unwanted chuffing noise. Cleverly positioned on the bottom of the speaker enclosures, it makes it possible to position the speakers anywhere in the room without altering their sound.

3-way system

The Theater 500 uses an authentic 3-way driver system. The amply equipped system employs a total of 2 bass woofers with lightweight but rigid Kevlar membranes to produce deep, resonant bass without an additional subwoofer. The midrange drivers and tweeters delineate voices and instruments with incredible precision, resulting in an almost tangible soundscape.

Advanced Klippel measurements are used to make an already excellent system even better. This technology uses lasers to detect tiny imperfections along the driver membranes, allowing them to be corrected for an improved frequency response.

Teufel Time Alignment Technology
The Theater 500’s recessed tweeter corrects differences in propagation time for a well-structured sound. Vocals, instruments and sound effects are rendered clearly and with great naturalness. Just like a live event, you’ll be able to distinguish the relative positions of the instruments and vocalists to each other.
Teufel home cinema loudspeaker Theater 500s Membrane
Constant Directivity Concept

A newly designed wave guide and phase plug gives the system a broad and even sound dispersion. This makes it possible for everyone in the room to enjoy the same well-blended sound with excellent speech intelligibility and localisation.

Innovative damping chamber
Inside the Theater 500, a specially designed damping chamber employs the concept of Helmholtz Resonance to minimize standing waves within the enclosure. This does away with the need to damp the bass reflex vent, allowing the low end to go deeper and work more efficiently. The result is an especially balance soundstage across all volume levels.
Downward-facing bass reflex system
The Theater 500 uses a downward-facing bass reflex system for anywhere room placement. A special oversized vent prevents the creation of wind noise at high volume levels.

Centre with two midrange drivers

The compact T 500 C 16 centre speaker offers impressively powerful playback. Use the integrated keyhole brackets to wall mount the speaker directly under your TV and enjoy incredible speech intelligibility.

The T 500 C 16 also fits easily on a shelf. The included base can be removed for wall placement.
Acoustically, the centre offers an exceptional performance thanks to:

  • A linear frequency response
  • Two midrange drivers for excellent speech intelligibility
  • High performance drivers for minimal distortion at high levels
Heimkino-Lautsprecher Theater 500 Heimkino 5.1 Surround Center-Lautsprecher
Dipole speakers for an authentic cinema atmosphere

Dipole speakers are specially designed for use as rear speakers in a surround system. Instead of radiating sound directly towards the listener, dipoles disperse phase-shifted sound in two directions. The listener perceives a diffuse atmosphere that fills the room, the same effect large cinemas achieve with a large number of speakers arranged behind the viewers.
For gamers, the Theater 500 Surround’s dipoles can be switched off for better localisation of objects and opponents. Each T 500 DR 16 dipole comes with integrated keyhole brackets for easy wall mounting.

The new subwoofer

The S 6000 SW is Teufel’s premium universal subwoofer model designed and developed in Berlin. The active sub is powered by an extremely low-noise amplifier with plenty of setting options including volume, phase switch, auto level switch and high pass filter. A recessed amplifier makes it possible to place the subwoofer directly against the wall.
The S 6000 SW employs a 300 mm woofer to push the low end all the way down to 28 Hz. Teufel’s proprietary Air Stream Bass technology uses a specially constructed air vent to minimized wind noise at high levels.

"The real breadwinner of sound"
HiFi Vision 21|2017
Conclusion:

"For a total price of 1.700 Euros Teufel presents a exciting and fair step up in the world of sound for upmarket home cinema. Above all, lovers of real home cinema sound with all its shades and full dynamics will love the Theater 500 from Teufel. The powerful stand speaker set brings the cinema-typical diffuse sound into the home four walls very well. The surround sound set is consists of a potential centre speaker, with a active subwoofer and two Dipol rear-speakers. And matched with the more discreet design thet set can easily fit in to any room. With this Teufel presents its third generation, and imporved version on the market."

Theater 500 Surround "5.1-Set" review of www.av-magazin.de
"with higher sounds and grand sound for music and films - equally impressive"
www.av-magazin.de 19.12.2016
"The Theater 500 Surround Set sounds incredibly broadband and agile. The film music is distributed very nicely in the room, so that one has the feeling of being directly involved in the cinematic events. The subwoofer accompanies the acoustic stage with abysmally deep but nevertheless clean bass, while the highs come along with crystal-clear and resolving melt. Thanks to the delay-corrected arrangement of the drivers, the spatial staggering of film music and sound effects is perfect.

"The Teufel set shines with a first-class locating sharpness that lets the laser cannons wander through our listening room. The explosions are transmitted by the huge active bass. The subwoofer is extremely powerful and level-resistant, which does not lose its expressiveness even at high volumes.

"The film dialogues are also brilliantly transformed by the centre. Thanks to the high chassis quality and the tonal-neutral overall tuning, voices sound particularly natural - even outside the sweet spot. The 5.1 set of Cece Winans' Gospel-Jazz is a brilliant example of this. The velvety soul voice sounds with such vivid authenticity that you inevitably get goose bumps."

"this is what home cinema should be"
Heimkino Magazin 12|01-2017
"The Teufel set reproduced our test film "X-Men: Apocalypse“ in top form: Punchy and dynamic with incredibly thrilling sound effects thrown into the listening room. Lively sparkling ice crystals are wonderfully separated from the rich, low frequency rumbling in the fight scene during the opening sequence. The dialogue between the main characters can also be clearly heard in spite of the complex sound effects. The Teufel set plays from all channels as from a single mould, but still allows special effects to be clearly distinguished and the action to be distinctly localised in the room. There are no unpleasant spikes in the sound, no noticeable colouration or compression artefacts, even in the treble range, and the subwoofer clearly enjoys playing with the set – this is what home cinema should be. All-in-all, the new set hasn’t lost any of the git and dynamics of its predecessor, but rather gained in terms of subtly and precision.”

Conclusion:
"The new Theater 500 Surround can be recommended to those who love home cinema sound with full dynamics and all gradations of sound. The clever tower speaker set paired with a potent centre, two rear dipoles for a immersivley diffuse sound typical of cinemas and powerful active subwoofer transforms every living room into a true home cinema. The Theater 500’s workmanship is more than adequate and the 5.1 set’s discrete design can be easily integrated into any interior.”

Help regarding this product
Do I also have a 6.1/7.1 playback for a 5.1 recording?
Usually, all 6.1/7.1 AV Receivers can generate a 6.1/7.1 playback from a 5.1 recording. The procedure is comparable with the Dolby Pro Logic Decoder, which generates a matrix circuit from the stereo signal of a centre channel.

The AV Receivers thus generate a rear centre channel from the rear R/L channels of a 5.1 recording through the matrix circuit. The stronger the rear R/L effects on the DVD, the stronger the signal from the rear centre.
Can I connect the LT 4 directly to a DVD player or PC?
No.

The LT 4 is a partially active system that requires AV receiver operation. It has a built-in amplifier that only supplies bass tones in the subwoofer housing That is why an "AV Receiver", i.e. a combination of radio receiver and multichannel amplifier, is essential for using the LT 4.

The subwoofer is connected from the Line In R input to the AV receiver's sub out jack using a mono RCA cable, while the three front satellites are connected to the three speaker outputs of the AV Receiver using the speaker cable and are supplied with power from there.

Connect signal-emitting source appliances such as DVD player or PC etc. directly to the corresponding input jacks on the AV Receiver.
When would it be worth upgrading my 5.1 system to 6.1/7.1 sound?
Naturally 5.1 channel systems that play back all of the sound tracks contained on the DVDs already offer an excellent home cinema experience.

For the new 6.1 or 7.1 sound formats, a rear centre channel is controlled in addition to these channels. This channel, coded in the stereo effect channels, enables the better positioning of effects and music signals directly behind where you are sitting.

If using two speakers for the rear centre channel, the optimal seating position is not tailored to an individually specified position, i.e. you don't have to be seated in the exact centre.

In the following cases we would recommend upgrading to a 6.1 or 7.1 system:

• Your sitting position is not always dead centre, or you often have several viewers

• You have had a 5.1 system for a very long time and would like an improvement

• Your AV amplifier/receiver is designed as a 6.1 or 7.1 receiver and offers the corresponding connection possibilities

• You can also set up one and/or two rear centres. If you are currently building/renovating your house or flat, we would recommend you lay the cables for the additional rear centre channels in any case.

• Modern BluRay players usually issue a true 7.1 surround sound signal at all digital outputs and are thus optimally suitable - presuming the relevant AV Receiver - as a signal transmitter for a 7.1 channel home cinema system.
How do I upgrade my system to a 6.1 or 7.1 sound format?
The choice of speaker(s) depends on the AV Receiver/amplifier. This has an additional power amplifier for one rear centre (6.1) or its two (7.1). You can easily see this by the wattage (e.g. 6 x 100 watt or 7 x 100 watt). To the existing (side) rear speakers for right/left (5.1 technology), one or two additional rear centres are utilised in addition (6.1 or 7.1 technology).

• My AV amplifier/receiver has six connections/power amplifiers (6.1):

In this case we recommend connecting the same centre at the rear that you also used in the front area.

• My AV amplifier/receiver has 7 connections/power amplifiers (7.1):

If you already use dipoles or direct emitters for your 5.1 system, then you have a choice of either supplementing two more dipoles or two direct emitters. For wall assembly and a short distance from the seating location to the rear wall (less than 1.00 metres), we would recommend dipoles. As soon as you want to set up the speakers on bases or on a shelf, then direct emitters would be the better choice.

Information:
Even if the AV Receiver/amplifier only has the connection and power amplifier performance for one rear centre, it is still possible to connect two instead of just one speaker through series connection.

Exception:
• The AV amplifier/receiver has seven connections/power amplifiers, but I can only set up one rear centre. As the 7.1 AV amplifiers/receiver also offer the option of operating just one of the two outputs (usually can be set in the speaker set-up!), you can also only connect just one rear centre.

Here we recommend connecting the same centre to the rear that you also used in the front area. For short distances to the listening location (less than 1.00 metres), a dipole would be the better choice - especially if you are also using dipoles at the sides.
Is it a problem if the speakers are at different distances to where you are sitting?
Since the distance and volume of every individual speaker can be adjusted for the digital home cinema receivers, asymmetrical set-ups can be easily compensated. 
How do I equalise my home cinema system with the help of a sound level meter?
Take the level meter with you to the listening position and point the measuring device directly towards the front centre speaker. Now start the sound generator of the receiver (or of the sound card or DVD player) and equalise all speakers in succession to the same level.

The position and alignment of the measuring device should not be changed during this procedure. For a Teufel sound level meter, proceed as detailed in the following:

1. Remove the protective tab from the battery.

2. Set the weighting to "A" - only the "A" position considers the full frequency range during measuring!

3. Set the response to Slow.

4. Set the Range to 70.

5. Start the test noise from your AV device.

6. Change the volume for every individual channel at the AV device so that the level meter shows 75 dB (meaning between +4 and +6).

7. Done!
What is the difference between the 5.1 and 7.1 configuration?
Compared with the 5.1 set, the 7.1 set has two extra speakers for the back rear centre channel.

The 5.1 channel set plays back all sound tracks on DVDs/Blu-rays and creates an excellent home cinema experience.

With the 7.1 sound format, a rear centre channel is also generated in addition to these channels and distributed to two further speakers (the "rear centre"). This channel, which is encoded in the stereo effects channels, allows better location of effects and music signals directly behind the sitting position.

If you use two speakers for the rear centre channel (i.e. installed 7.1 set), the optimum sitting position is not restricted to one specific place, so you don't have to be sitting exactly in the middle and several listeners can enjoy the best sound.
Where is the optimal place for the centre of my Lautsprecher Teufel Surround System in a 5.1/6.1/7.1 configuration?
Because the centre plays back spoken dialogue, this speaker must be positioned as centrally as possible under or over the TV/monitor or the screen.

If the centre is placed outside the area of 40 centimetres to 1.20 meter height, it should be slightly inclined or angled towards the listener.


Which speaker cables does Teufel recommend?
For smaller sets up to Theater 1, we recommend using the 2.5 mm² Teufel speaker cable for optimal sound quality if the required length does not exceed 15 metres.

For Theater 2 and larger systems, we recommend the Teufel cable with 4 mm² cross-section for the front/centre speakers, and the 2.5 mm² cable up to a length of 15 metres for the effect speakers.

Choose a higher cross-section for even greater lengths.
Which cables do I need to connect a Teufel speaker set to the AV Receiver?
A home cinema system needs speaker cables to connect the satellite speakers to the receivers, and an NF mono RCA cable to connect the active subwoofer to the sub out socket of the AV Receiver.
Is it possible to combine speaker cables with different cross-sections?
To supplement missing cable lengths you can use speaker cables of differing thicknesses without acoustical differences - provided there are no extreme differences in the cross-sections.
Should I rather choose a fully active or a partially active speaker set?
It is compulsory to connect partially active systems to an AV Receiver. This supplies the five to seven satellite speakers with the necessary power. Only the subwoofer works additionally with its own amplifier. The investment in a new system is higher because of the AV Receiver, but the solution is also much more flexible. After all, you can connect several signal sources, such as a TV, satellite receiver, PC, game console and MP3 player to an AV Receiver at the same time.

Fully active set do not necessarily need an AV Receiver. The five to seven satellite speakers here are supplied with power by the amplifiers which are installed in the subwoofer in addition to the subwoofer power amplifier. This saves you the costs of a receiver, but it is usually only possible to connect one source to our fully active subwoofer.

Exceptions here are the Concept E2, the Concept E Magnum Digital, the Motiv 5 Digital, the Concept F, the LT2+R and the Concept S+R.

Naturally you can also equip the fully active systems with an AV Receiver at a later point. The connection is then equal to the partially active sets.
When can I use the rear speakers as direct speakers?
If you aren't able to position the speakers close to the wall as described above, you should use the them as direct speakers. For this purpose the rear switch should be tipped outwards. For use as direct speakers, the rear boxes should be set up to the left and right of the listening position - ideally at the same height, e.g. on a shelf or preferably on a base. If the speakers have to be set up so that they are much higher or lower, it may be advisable to align them to the listening point. For wall mounting it is best to use wall brackets that allow for vertical movement. When using the speakers in direct speaker mode, we recommend that the distance between the two rear speakers exceeds the listening position by 1m. But if you (have to) sit closer, please make sure that the front of the speaker is not pointing directly at you; instead, angle the speakers more into the room.
Can I set up the set in a different way to that described?
The recommended set-up information below represents the best possible arrangement for perfect multichannel playback in your home. Your available space, your partner or your furniture may not always allow you to arrange the speakers in the ideal manner. Try to meet as many of the requirements as possible.

Modern AV Receivers offer numerous options for compensating electronically for any compromises in the set up. Generally speaking, the following rule always applies: you can always use our recommendations as a basis for experimenting with what works best for you, acoustically and optically. Let your ears (and eyes) decide!
Do I need the same cable length for all speakers?
In our experience, there is no acoustical difference for different cable lengths for lengths up to 15 metres.
The RAMPA insert at the bottom of the speaker sometimes is turned out with the tamping screw. What can I do about that?
Unscrew the tamping screw from the Rampa insert and screw the Rampa insert back into the bottom of the speaker.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
What is the advantage of bi-amping/bi-wiring?
Bi-amping means that the speaker can be operated by two amplifiers at the same time, or by a bi-amping-capable AV receiver. This enables the different chassis (for the treble mid-tone and bass range) to be individually supplied with one signal. Among other things, this could increase the sound performance of a speaker.

Bi-wiring states that the corresponding speaker can be controlled at the same time with two different speaker cables, meaning via separated input sockets for the treble and mid-tone range on one hand, and for the bass range of the frequency switch on the other. This could improve the sound even more. Bi-wiring is the prerequisite for bi-amping.
Could I also put a dipole such as the M 500 D on a base?
In theory, dipoles can be placed on bases providing they are always near a wall, but we cannot supply any bases that are of the recommended height of 1.50 metres. Stability at this height can only be guaranteed if the base plate is very big.

A base of around 1 x 1 metre isn't going to look very attractive. Perhaps your joiner will be able to make you something that will match your room. Otherwise you should also use direct speakers for the surround channels, preferably of the same model as the front speakers.
Is it possible to set up dipoles behind the listening location on the rear wall?
Yes. Alternatively, you can also use wall brackets to position the dipoles behind your seating location at a height of 1.40 to 2.10 metres. Almost all Teufel dipoles have an integrated M6 tamping screw in the bottom to accept wall brackets.

We recommend mounting the dipoles using the suitable, optionally available swivelling L wall bracket and then aligning the dipoles at a 45 degree angle slant to the inner lying speaker-equipped side to the back wall and aligning the other speaker-equipped side to the side wall. This causes the dipoles at the back and side walls to reflect, thus generating the desired diffusivity.
The distance of the dipole-side equipped speaker to the room side wall should be at least 10 centimetres.
Is it possible to set up dipoles on bases to the sides of the listening location?
A set-up close to the wall is possible in principle, but we cannot offer bases with the recommended height of at least 1.40 metres. Stability at this height can only be guaranteed if the base plate is very large.

However, a base of roughly 1 x 1 metres is certainly not a pleasant sight. Perhaps your joiner will be able to make something that matches your room.

Otherwise, you should use direct emitters for the surround channels as well - the same models as for the front speakers is best.
Why does the automatic calibration of my AV Receiver report "incorrect" polarity for the rear speakers even though my dipoles are connected with correct polarity?
The reason for the error message is that the calibration functions were primarily designed for direct-emitting speakers.

However, as soon as dipole speakers are utilised, error messages can occur due to the spatial playback, because the dipole concurrently emits both phasings - the correct one and "the wrong one".

The reason why one speaker is displayed as "correct" and the other one as "incorrect" polarity is because sound is reflected variably due to the spatial conditions and consequently arrives variably at the measurement microphone. Depending which proportion of the sound is recognised by the microphone first, the receiver then decides whether there is (an assumed) false polarity or not.

Because polarity is visible based on the pole clamp markings on the speakers, you may ignore the measurement of the receiver.
How do dipole speakers work?
Dipoles do not simply emit sound directly forwards, but emit towards the front and back in shifted phases.

This means that if you were sitting on an axis between the dipoles, the direct sound of the front and rear side of the dipoles is cancelled and you primarily hear the room reflections. This simulates the sound field of a cinema where the surround channels are played back by several speakers in each case. That is why the dipoles are mandatory for THX Ultra2 systems.
How do I position the dipoles for slanted walls in an attic storey?
The dipoles should be hung on the slanted wall/ceiling to the side of your listening location.

All Teufel speakers have an M6 tamping screw at the bottom of the housing to fasten the dipoles to a sturdy L-Lock bracket, available in the Teufel accessories programme.
What are the advantages of dipoles as compared with normal, direct-emitting speakers?
Only dipoles can transfer the atmosphere of the cinema sound par for par to a living room. The surround field for dipoles is broader and thus fills the entire rear area, whereas for direct emitters (normal speakers) you always hear the speakers directly. As direct emitters sound similar to the front systems, the atmosphere that creates three-dimensionality is missing as compared with the dipoles.

The disadvantages of dipoles is the necessity of positioning them on the wall (upwards of 1.40 metres) and the more expensive price: They usually cost more than normal direct emitters, as you require the double number of chassis to be used. For limits in price, the following general rule applies: better have good sounding direct emitters than bad dipoles.
Where is the optimal place for the dipoles?
The dipoles should be best mounted to the side of the listening location at a height of 1.40 to 2.10 metres. Many Teufel dipoles already have an integrated wall bracket. We offer the corresponding brackets for the other models, e.g. the L-Lock bracket.

The dipoles then emit towards the front (direction of TV/screen) and the back (direction of back wall) so that direct sound is not heard at the listening location. The distance of a dipole-side equipped speaker to the back wall should be at least 10 centimetres. If your living room does not permit the assembly in the described form, we will be happy to advise you.
Are THX dipole surround speakers also suitable to play back 5.1 channel sound formats?
Of course.

The dipole surround speakers simulate exactly the sound fields of the speakers installed at the rear and side walls of cinema theatres, providing an especially impressive surround experience.

As it is impossible to mount a similarly large amount of surround speakers in your living room at home, the THX dipole surround boxes are the best space-saving way to transfer the surround effects to the home cinema.
They provide a precise positioning of certain sound effects, yet immerse the listener in a room-filling surround atmosphere.

One never has the impression that the sound is being directly emitted from a speaker.
How do I set the switch on the dipole?
Dipole setting: The speakers operate in phase opposition, i.e. if one side is transient, the other side dies out.

Bipole setting: The speakers operate in phase, i.e. both sides die out on the same side.

Monopole setting: Only the front side of the dipole is activated, i.e. the speaker works as a direct emitter.

On current dipole models (e.g. t 130 D) the two positions of the switch for the dipole and direct radiator mode are not specifically marked. If the switch is set towards the wall, the dipole mode is on. If the switch is set towards the speaker cabinet, the direct emitter mode is on.
My subwoofer is humming. What can I do?
This hum can be caused by the connected devices or disruptions in your electricity current. Please do a test to see which it is.

1. Remove the RCA cable from the input on the subwoofer. If the hum is no longer heard, go to point B. Otherwise, follow point A.

A. Attach the net cable of the subwoofer to another electricity outlet (i.e. Kitchen/Bathroom/Bedroom). If the subwoofer still hums, get in contact with our Support team.

Should the hum no longer be there, the disruption was a problem in your power supply, which can, for instance, be caused by dimmers or chargers. To find out where the disruption is, unplug all your devices and work back from there. As soon as the hum is heard, you now know your source of the disruption.

B. In your case, the "ground hum" is responsible for the disruption. Please proceed as follows to discover your source.

  • Disconnect the cable or satellite port from the TV Receiver and check if the hum disappears or not. If it does, you can use a sheath current filter for the cable outlet to prevent this. For example, the sheath current filter AC 9022 ED. If you have a satellite connection, connect the Satellite Receiver to the optical cable playback source - Teufel Optical Digital Cable

  • If this reason can be excluded, separate all devices from the AV Receiver one at a time until the hum stops. The last connected device is then your hum source and should be separated from the others using a galvanic separation filter (found in a retail shop)

  • If this doesn't work, get in contact with us once again so that we can give an individual, helpful response.
Will an active subwoofer only run in 5.1 mode or also in stereo mode?
Thanks to the speaker set-up/bass management integrated in the home cinema receivers/amplifiers, the subwoofer functions in stereo, Dolby Surround and digital mode.

The corresponding setting in the speaker set-up must be adjusted individually for each source for many receivers, however, e.g. for CD playback only front without woofer, and front speakers plus woofer for Dolby Surround video playback.
Why doesn't my active subwoofer switch on automatically?
Some AV Receivers/amplifiers issue the bass signals via the subwoofer pre-amplifier output so quietly that the subwoofer does not start automatically.

To make sure the subwoofer switches on and off correctly in automatic mode, (to be selected on the corresponding switch of the subwoofer, such as "Auto / On / Off"), we recommend turning the level control on the subwoofer to 1/3 or perhaps to 1/2 and increasing the output level for the sub in the receiver's speaker set-up – sometimes up to the maximum (+10 dB or +12 dB). The subwoofer should then work perfectly.

The maximum position of the output level in the speaker set-up of the AV Receiver is obligatory for some of our models (e.g. the Concept S subwoofer).
How do I connect my fully active Teufel system to an AV Receiver?
Although designed to be fully active, the Teufel set is also partially active in conjunction with an AV Receiver.

You can connect it like a standard speaker system: the five satellites via speaker cable to the corresponding speaker outputs front R/L, rear R/L and centre of the AV Receiver/amplifier and the subwoofer from the front R input via a mono-RCA cable to the Sub Out output on the A/V Receiver/amplifier.

Please note:
The auto on/standby switch only responds when the front R input is being used! The subwoofer also receives the full subwoofer signal via this channel.

If the AV Receiver/amplifier has preamplifier outputs for all channels (front R/L, rear R/L, centre and subwoofer), the Teufel set can also be connected via three RCA cable pairs to the subwoofer and the satellites via speaker cables to the subwoofer. However, we recommend using the first version.
What is a ground hum?
The hum (50 Hz) comes from the 220 volt supply network and is caused by current power flows through the protective conductor. These so-called "ground hums" is caused when you connect two devices that are already grounded on the protective conductor (subwoofer) or the antennae cable (AV Receiver) to the subwoofer cable.

Solution:
Separate the direct connection by a grounding filter for the antennae cable that is created for it - for instance, the Teufel modell sheath current filter AC 9022 ED. Alternatively, you can use a galvanic separation filter that is looped into the connection between the subwoofer and AV Receiver.

The hum disappears if the antennae cable is separated from the Receiver/Tuner/TV. First try the grounding filter, otherwise the galvanic separation filter.
Where is the optimal place for the subwoofer of my Lautsprecher Teufel Surround System in a 5.1/6.1/7.1 configuration?
The location of a subwoofer with a recommended cut-off frequency of under/equal to 120 Hz can be freely selected and does not affect the other speakers.

Placement within the straight line between both front satellites is ideal - but not precisely in the corner of the room because certain frequency components could be unpleasantly excessive when played back.
How do I determine the right phase setting of the subwoofer?
By setting the phase, you can affect the point at which the membrane of the subwoofer bass speaker moves to the front. This setting makes it possible to optimally adjust the subwoofer to the satellites.

The membranes of the satellites should move to the front at the same time as the membrane of the subwoofer bass speaker, because all speakers of the system must vibrate in phase for optimal playback. This means that (provided the connection has the correct polarity) all drivers must move in one direction when the three front speakers receive a pulse (towards the outside or towards the inside).

If the subwoofer is in line with the front speakers, its bass speaker should have the same direction of movement (phase) - the controller on the woofer is set to "0". If the subwoofer is not between the front speakers, but is to the side of or even behind the listening location, its phase length will not match that of the front speakers. That is why the phase of the subwoofer must be changed in such cases.

So much for the theory. In practice, this means: Listen to a loud piece of music with heavy basses and ask a second person to change the phase during playback. The correct setting of the phase switch depends on where the subwoofer is positioned in the room. The position where the bass playback (above all the upper bass range) sounds the fullest is the correct position. Have fun trying it out!
What is the use of the on/off automatic switch ("Auto On/Off") of the active subwoofer?
The On/Off switch is a power-saving standby switch. The switch must be set to "On" or "1" to activate the standby. The subwoofer is activated as soon as it receives a strong bass signal. After approx. ten to twenty minutes of no signal, or only after receiving a very weak signal, it automatically switches to the standby function.

Even though the LED is still illuminated, the subwoofer is in standby mode. This function can be easily checked by slowly increasing the volume at the receiver/amplifier. You will hear a quiet popping noise when the subwoofer activates itself as of a certain level.
What happens to the power amplifiers of the subwoofer if I don't connect the satellites?
As soon as the satellites are connected to the subwoofer and not to the AV Receiver/amplifier, the performance of the 6 or 8-channel power amplifier is distributed to the subwoofer and to the satellites.

If the satellites are not connected directly to the subwoofer but to the AV Receiver/amplifier via speaker cable instead, the subwoofer performance will increase somewhat; the power amplifiers for the satellites have no function. This enables the subwoofer and satellites to play even more dynamically than if the subwoofer still had to provide the satellites with performance.

The technical background: The subwoofer has a large transformer with a specific wattage. This performance is either distributed to the five satellites and the subwoofer, or you receive a higher performance only for the subwoofer.
How can I connect an additional active subwoofer?
If your receiver has only one subwoofer output ("Sub Out"), you only need a monocinch cable, which is then connected from the receiver to the "Sub In" of the subwoofer. With two subwoofer outputs, you can order a so-called Y-adapter from the Teufel accessories page, which has a cinch plug on one side and two cinch (RCA) sockets on the other. Connect the plug to the subwoofer "Pre Out" on the AV receiver/amplifier and connect the mono cinch cable to the two subwoofers.

If the cabling method is easier for you, then you can alternatively connect one subwoofer to the other. You will need two mono cinch cables - one to connect the subwoofer "Pre Out" on the AV receiver/amplifier to the left line-in input of the first subwoofer, and the other to connect the left line-out output of the first subwoofer to the left line-in input of the second subwoofer.
What's the deal with the so-called bass traps or bass absorbers?
These are usually cubic wood housings (same MDF material as the speakers) with a bass reflex opening that have no membranes and are tuned to a certain frequency (e.g. 40 Hz as for a subwoofer). The frequency to be co-ordinated can be changed by the length and diametre of the bass reflex channel. If, for example, a room has a room resonance frequency of 28.3 Hz and this frequency is also played back in addition by a speaker/subwoofer, the room will begin to resonate at this frequency. This particular frequency is played back amplified.

This can be imagined as droning or booming, which occurs during heavy bass movie scenes such as explosions or certain types of music (Jazz, pizzicato bass). The bass absorber is then tuned exactly to this frequency so that only the speakers/subwoofer play back this frequency. The resonance frequency from the room, which would amplify this frequency, is swallowed by the bass absorber.

If you would like to damp more than one frequency (a room usually has three different frequencies: ceilings and floors, front and back and left and right, and its multiple), you will have to set up three absorbers accordingly.
How is the wattage of a subwoofer with respect to the sine wave and pulse/music performance?
Mono subwoofer:

The wattage (e.g. "360 W") printed on the rear of the subwoofer near the mains plug designates the ability of the power amplifier "to pull" a maximum power rating in the specified range at the moment of switching on (those 360 watt stated as an example).

Consequently, the wattage must correspond to at least the sine wave output of the amplifier, as this sine wave output must be permanently available which the power pack must provide as well.

The pulse/music performance of the amplifier, on the other hand, can exceed the wattage, because the short pulses are buffered additionally by the capacitors in the power pack and are not achieved solely through the performance of the power pack.

Multi-channel subwoofer:

The wattage for a multi-channel subwoofer can also be below the sine wave output, as the specified sine wave output is not requested from every channel at the same time.

For a 5 x 100 watt sinus power amplifier, for example, each of the five channels is able to implement 100 watt sine. However, not all five channels at the same time! This is also unnecessary, as the same signal is never transmitted across all five channels at the same time, thus requesting the same high sine wave output per channel.

That is why the wattage may be, e.g. 300 watt, even if the sine wave output exhibits 5 x 100 watt (= 500 watt).
What are the volume switches for?
The sound of the speaker always depends on the room where it is located.

The volume of the active subwoofer can be controlled so that you can adapt the relationship between the active bass and treble / mid tones to suit the room.

Use your own senses to judge which settings sound best in your room. This switch is especially useful in stereo mode. On the other hand, multichannel amplifiers often have technologies that adjust the subwoofer volume - so when using a multichannel amplifier the controller should first be set at 0dB.
Which subwoofer cables does Teufel recommend?
Dans la mesure où dans un ensemble home cinéma les caissons de basses actifs sont connectés à la sortie Out du caisson de basses du récepteur AV, un câble supplémentaire pour la connexion des enceintes satellites est nécessaire. Pour les caissons de basses actifs nous proposons deux versions de câble mono RCA NF allant de 2,5m jusque 5m. Du reste, un adaptateur Y est également disponible dans nos accessoires. Le modèle „ 2 x mâles 1 x femelle“ permet un usage complet des entrées Line-In RCA droit et gauche au caisson de basses. Ainsi, la puissance du caisson de basses s’en voit augmentée. Le modèle „1 x mâle 2 x femelles“ permet la connexion de deux caissons de basses. Une sortie caisson de basses Pre-Out du récepteur se trouve en sommes doublée.
What is room resonance frequency?
Room resonance frequency (other terms: room modes, standing waves, resonance frequency) is the frequency at which the vibrations of a voice, a musical instrument or a signal played back over the hi-fi/home cinema system is amplified unnaturally, because the vibrations build up between the walls as well as the floor and ceiling.

It is calculated of the sound velocity divided by 2 and divided by the room length [ 340 m/s: 2 : 6 m = 28.3 Hz (=1/s) ] or, more simply: 170 divided by the room dimension (length, width or height). The greatest distance between two parallel walls is taken as first standard value. For a room of 4 x 6 metres, this would be 6 metres. Strictly speaking, you would have to calculate the room resonance frequency for further parallel walls (for the 4 metres and for the ceiling height).

Overlaying resonances are also possible if the room dimensions are very close to each other. (2.8 metres high, 3 metres wide and 5.6 metres long). The resonance at 2.8 metres is repeated as multiple (times 2) at 5.6 metres length, the resonance of the 3 metres width is close to the resonance of 2.8 metres. It would resonate strongly here at 30 Hz, 56 Hz, 60 Hz and 120/112 Hz.

Phenomena of resonance frequencies:

• For example, a man with a deep voice speaks in a very small room (2 by 2 metres, 85 Hz). The voice appears to have more emphasis than in another room or out of doors. As soon as a woman speaks, the voice will sound just the same as in another room.

• The voice of a woman or that of a small child will cause glass to shatter. The voice strikes exactly the tone that corresponds to the resonant frequency of the glass. The glass resonates so strongly that it shatters (refer to the movie "The Tin Drum").

• A group of soldiers march across a bridge in cadence. The equal movement causes the bridge to vibrate so much that it collapses. That is why no one marches across bridges in cadence.
