"with this system, Teufel offers the best THX loudspeaker set in Europe, perhaps even the world."
Hifi Vision 23|2012
"For the past few years, Teufel’s Theater 10 has been considered the best home cinema loudspeaker system in Europe. But the THX market leader now has some competition – from the same manufacturer. With the System 10 THx Ultra2, Teufel wants to, once again, set a new benchmark. Born out of Star Wars, no other acronym in the speciality segment of home cinema is ranked higher than THX. Contrary to what many film fans think, it’s not just a sound format, but rather a sort of cinema and home theatre quality seal dating back to 1982. Back then, a young, up-and-coming film director names George Lucas contributed to the meticulousness of a unifying a quality standard for cinema. In order to be certified, the products need to meet certain standards with regard to linearity, power performance, depth and dispersion characteristics, to name just a few of the criteria. THX presently offers different standards for different requirements, budgets, and room size of which the THX Ultra2 represents the ultimate certification. Teufel Audio is among the manufacturers who have fulfilled the highest THX standards for its multichannel systems, which makes the Berliners one of the most respected manufacturers for home cinema products today.”

Conclusion
"Teufel fulfills the promise of its advertising by truly settting a new benchmark in the reference class of THX multichannel systems. Beyond that, with this system, Teufel offers the best THX loudspeaker set in Europe, perhaps even the world. It’s difficult to say if the sound performance could be topped. I, at any rate, don’t know how.”

Result: 90% - “excellent”
Digital Tested 11|2011
In general, the directivity of the FCRs is considerably more to the fore and less to the sides which creates a very good result. The flexibility in the dispersion characteristic of the surround dipoles is equally beneficial, because along with supporting a diffuse cinema atmosphere or a localisation dependent on directionality, they are well integrated into the sound system. The subwoofer seems to dispatch with an inexhaustible deep frequency performance in the room, and thereby provides a rock-solid foundation for the system. Its sealed construction supports an expecially concise and powerful sound-scape. The set is therefore to be recommended as an ideal solution for fervent home cinema fans.

Assessment:
The System 10 is not only a visual highlight, but makes a powerful sonic impression. Those who have the requisite room size at their disposal will have a lot of fun with this surround set for a long time.

"It masters the balancing act between the immediacy of film and the airiness of music, and the level reserves can barely be plumbed."
audiovision 05|2000
The dynamic bass playback is utterly impressive: Monster films like "Cloverfield“ unfold especially thrillingly with deep bass attacks that suddenly engulf the audience. If one takes the bass to its performance threshold, a full 116 decibels can be physically felt. Yet the subwoofer behaves with great restraint: The sealed cabinet doesn’t drone or crack. Only a soft swooshing noise streams through the amplifier’s cooling vent. The low levels of distortion in combination with extreme level reserves across the entire frequency range lead one to strain both ears and amplifier - so be careful!

Stereo sound quality

Whether soft or lukewarm, the character of the sound barely changes. Neither faults nor compression comprise the sound with increasing volumes. The subwoofer and satellites complement each other well: Well mixed songs like “Me and Armini” sound balanced, the acoustic differentiation of the bass is exceptional. Snare drums or the fortissimo of a Steinway grand piano in the higher octaves ring forth with a relaxed and highly dynamic sound.

[...]

Conclusion
Teufel’s largest cinema speaker set won us over. It masters the balancing act between the immediacy of film and the airiness of music, and the level reserves can barely be plumbed. The mighty subwoofer doesn’t reach infrasound territory, but the bass is consistently clear, dynamic and fills even gigantic rooms.

"Exzellenter Surround-Klang"
AUDIO 11|2011
Die Basswiedergabe war unglaublich gut: Richtig auf- und eingestellt, faszinierte der Subwoofer bereits bei niedrigen Pegeln mit seiner unaufdringlichen Art, sich am Sound-Geschehen zu beteiligen. Mit Kinotypischen LFE-Effekten und ab einer gewissen Lautstärke zeigte der Woofer jedoch unüberhörbar, was Sache ist - wie der Autor, nun breit grinsend, an seinen flatternden Hosenbeinen bemerkte. Ihre wahren Trümpfe konnte die Teufel-Anlage bei actiongeladenen Filmen ausspielen. [...] Das System 10 reagierte in allen Situationen mit einer beedinruckenden Dynamik, ohne dabei aufdringlich zu wirken. Krawall mit Kontrolle: Was Surround-Sets aus Hifi-Boxen meist an den Rand ihrer Fähigkeiten bringt, scheint dem THX-Set regelrecht Spaß zu machen.

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.


Why don't the THX Select and THX Ultra 2 have five identical speakers?
A cinema uses completely different surround and front speakers, as they must fulfill completely different tasks.

The front speakers guarantee clear voice reproduction and very good positioning that harmonises with the picture.

The surround speakers, on the other hand, generate a diffuse and non-traceable sound field that literally surrounds the viewers and enables the illusion of a helicopter flying over the audience, for example. If you want to set up a 5.1 home cinema system with conventional speakers, then five identical speakers plus a subwoofer are the minimum equipment.

THX speaker systems, however, are specifically designed for multi-channel playback. That is why THX front speakers and THX dipole surround speakers offer the best requirements for perfect sound playback from a psychoacoustic view.

Despite the very compact dimensions of all utilised speakers, the THX subwoofer provides a very dynamic and powerful bass playback.
Does it make sense to connect THX Ultra 2 speakers to a THX Select amplifier?
Since the requirements for THX Select devices regarding cut-off frequency, THX switches and speaker control are comparable, a THX Ultra 2 speaker system can indeed be combined with a THX select receiver.

The main difference to the THX Ultra 2 devices is their higher performance which is only necessary for an approximate room size upwards of 50 m².
How does the Music Mode of the THX Ultra 2 work?
The THX Music Mode is especially predestined for DTS 96/24 and DVD Audio. The company, previously specialised in optimising film sound, now offers a solution for the new, high-quality music sound formats, which function as follows:

It uses the speaker setting of a THX EX system with two surround and two back surround speakers, but the speakers are configured differently than for the playback of home cinema sound: The left surround is linked to the left back surround speaker and the right surround is linked to the right back surround speaker.

The meaning of this endeavour is to generate a phantom sound source, seen spatially between the respective surround and back surround speakers, whose sound impression should be similar to the sound image of a normal direct emitter due to the position and the radiation behaviour.

THX wants to achieve qualitatively convincing music and cinema sound playback using one and the same speaker system.
How is THX Ultra 2 specified?
THX Ultra 2 is the first THX standard that was completely developed for digital home cinema sound standards.

THX Ultra (1) was still based on the "original" Home THX, which was already used in high-quality AV amplifiers/receivers during ProLogic times.
Do I need a THX amplifier for the THX speakers?
Not necessarily!

The receiver/amplifier must have bass management where the frequencies are distributed for the THX front/centre speakers and the THX subwoofer (cut-off frequency 80 Hz).

Also, the amplifier should exhibit a minimum rating of 100 watt per channel and match the speakers for performance (amplifier sine wave output = approx. long-term load of speaker).
Are THX speakers suitable for listening to music?
Of course.

Since THX speakers are optimised to play back multi-channel signals (4 or 5.1 channels), the front speakers permit the precisely staggered and very true to detail spatial playback, while the surround speakers ensure realistic room characteristics.

Both are also ideal requirements for playing back music.
Is THX compatible with Dolby Digital and DTS?
Absolutely!

The objective of THX home cinema systems is to play back film soundtracks with as much authenticity and quality as the original mix from the sound studio.

In all studios used for film dubbing, the soundtracks are mixed in a 4-channel version (Dolby Surround) and in a 5.1 channel version. The acoustics, equalizer settings and speaker configurations are absolutely identical.

THX systems are thus always able to play back soundtracks produced in this way absolutely true to the original. Because of the high technical and tonal requirements, the THX standard can be compared with the TÜV (German Technical Control Board) for cinema sound.

As opposed to the THX quality standard, DTS and Dolby Digital are procedures for compressing sound data.
What is so special about a THX System?
THX systems are the ultimate home cinema components.

All THX-licensed devices and speakers must demonstrate certain technical properties so that they can play back movie soundtracks produced for cinemas and correspondingly powerful cinema sound systems absolutely true to the original for home cinemas as well. This is only possible up to a certain point with conventional hi-fi systems.

The most important requirements for excellent home cinema sound are:

• That despite the considerable size difference between cinemas and home cinemas, the movie soundtrack can be played back in comparably smaller rooms with the correct tonal balance and three-dimensionality.

• That all sound channels are played back very precisely despite the complexity of a multi-channel soundtrack to be able to precisely locate and allocate all noises and voices.

• That the subwoofer is perfectly coupled to the main speakers.

• That the front speakers are (by sound) identical - indispensable for harmonious sound playback.

THX systems satisfy these requirements perfectly, as they consider all running processes concerning playback while the movie soundtrack is being mixed.
What are the differences between THX Ultra 2, THX Select and THX Multimedia?
THX is a quality standard that guarantees the best possible playback for a specific room size. Since THX was originally developed for cinema theatres, the specifications apply to room sizes that far exceed the average living room size.

THX currently differentiates three standards for speakers: THX Ultra 2, THX Select and THX Multimedia.

THX Select 2 only applies to AV Receivers/amplifiers.
THX Ultra 2 corresponds to the earlier THX with the uncompromising design of the components.

Comparison of the three THX standards:

Front speaker
• THX Ultra 2: Angle of radiation and frequency response strictly limited requirement, D'Appolito arrangement of speaker systems prescribed.
• THX Select: More generous specifications for angle of radiation and frequency response.
• THX Multimedia: Radiation behaviour corresponds to THX Select.

Surround speaker
• THX Ultra 2: Dipoles are compulsory.
• THX Select: Dipoles recommended, but not compulsory.
• THX Multimedia: Direct emitters in every respect.

Subwoofer - transfer frequency

• THX Ultra 2: 80 Hz
• THX Select: 100 Hz
• THX Multimedia: 130 Hz

Volume level

• THX Ultra: Continuous load 105 dB (front) / 102 dB (surround).
• THX Select: Short term load 105 dB (front) / 102 dB (surround).
• THX Multimedia: 103 dB at the listening location/desk at approx. 50 cm distance.

Performance profile

• THX Ultra 2:
More output performance than normal AV Receivers. Complies with the strictest requirements for minor background noise and minor distortion. Is designed for performance needs of large listening rooms up to 150 m².
• THX Select:
Structure of AV Receiver is simpler and thus more reasonably priced. Less performance required, therefore suitable for smaller and medium-sized listening rooms up to approx. 50 m².
• THX Multimedia:
Pure PC and/or multimedia speakers for use at the computer.

Speaker set-up

• THX Ultra 2: Arrangement and set-up strictly regulated.
• THX Select: Set-up and arrangement simpler and more flexible.
• THX Multimedia: Set-up of front speakers on the desk, rear speakers to the side and behind where you are sitting.
How can I upgrade my THX system to a 7.1 sound format?
With the THX 7.1 amplifiers/receivers, there is always the option of connecting two rear centre speakers. We would also recommend using four rear speakers. Due to the elaborate development of our rear speakers, our models can be used very flexibly for any application. Here we have to differentiate as follows: - You have a THX Select/Ultra 2 device and want to connect two rear centre speakers: if you already use dipoles or direct radiators in your 5.1 system, you have the choice of adding either two more dipoles or two direct radiators as rear centres. For wall mounting and/or at a short distance from seat to rear wall (less than 1.00 m), we would recommend dipoles that are also operated in dipole mode (for System 4 THX, for example, order 2 x additional S 400 D). As soon as you want to place the speaker on stands or on a shelf, we would recommend direct radiators (for System 4 THX, e.g. order 2 x additional S 400 FCR). As soon as you already use direct radiators with your 5.1 system, we would recommend the same type of direct radiators for the upgrade. You have a THX Ultra 2 unit and want to connect two rear centres: a circuit especially developed for THX Ultra 2 devices allows you to use two more direct radiators or two more dipoles in addition to the dipoles used as rear effect loudspeakers.
What's behind THX Optimode?
THX Optimode is the latest development of the THX Digital Mastering Program consisting of a series of tests that enable every home cinema user to adjust his system exactly in picture and sound to the Optimode DVD currently in the DVD player.

The first DVD that supported the new feature was "Fight Club" in the Special Edition by 20th Century Fox (NTSC version). The offer has been continually expanded in the meantime.

The tests, which can be played on NTSC as well as PAL DVDs, consist of video tests that are helpful in optimally setting and configuring the TV or video projector, as well as audio tests that guarantee that the sound system is configured perfectly.

The special thing about these tests is the fact that the measuring signals are identical to the reference signals that were used during the final mixing of the relevant DVD. The home cinema system can therefore be co-ordinated accurately and individually to every single DVD with THX Optimode.

The goal of the entire procedure is that the sound and particularly the picture should appear in the home cinema exactly as the producer imagined. Let's assume the film producer wanted to create a certain mood in the film using specific colouring; this only works in the home cinema if the screen at home is just as co-ordinated as in the studio. Thanks to THX Optimode, that is guaranteed as far as possible.

Operating THX Optimode is just as easy: The software on the DVD includes all of the tests. Individually, these are video tests to set the contrast, brightness, colour, colouring, control of the correct ratio of picture length to picture width and the possibility to test the general qualities of the monitor.

In addition, there are audio tests for the phases of the speakers, connection of the speakers and the cut-off frequency of the LFE (subwoofer channel). Some tests will clearly show when it is necessary to consult a specialist for the settings.
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!
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.
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.
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.
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.
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.
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.
