Overview of our technologies

Downfire

The Consono 35 Mk2 5.1 set offers thrilling intensity at a reasonable price. If you’re in the market for a home cinema system with a rich sound, realistic effects, a thrilling cinema atmosphere, and dynamic music reproduction, look no further.

Chic & sleek with a rich sound
The Consono 35 Mik2 uses 5 identically constructed loudspeakers with two midrange drivers each to achieve a harmonious sound. The additional drivers makes their presence felt in the Consono’s optimal speech intelligibility and rich sound. Perfect for films, games, and music.

This powerful set plays perfectly with any standard home cinema A/V receiver. The satellites can be discreetly placed on the shelf whereas the centre is ideally placed directly under the screen. Alternately, all components can be mounted on a wall or on an optional stand.

The  rich sound spectrum in the mid and high ranges rests on a strong foundation: the sleek new subwoofer may not take up much space, but it uses an especially large, upward radiating bass driver (250 mm). Fired by an integrated 125 watt amplifier, the subwoofer masters the low frequencies in rooms up to 30 m² with a low end frequency limit of 40 Hz.

The Consono 35 Mk2 is the perfect expression of Teufel’s ideal price/quality relationship: This compact set concentrates all acoustic elements to their essentials resulting in more sound than is otherwise possible in this price class for an intense movie and music experience.

Consono 35 is a shining example of Teufel's extraordinary price-to-performance value. It features a lean design which concentrates only on the acoustic essentials – in short it delivers excellent sound available for less money. Expect to experience plenty of great cinema and music with it.

The US 2110/1 SW is a powerful active subwoofer

Weighing in at over 20 kg with a 45 litre volume, the US 2110/1 has what it takes to deliver extremely powerful and deep bass playback. The integrated 125 watt amplifier drives a large 250 mm woofer down to 38 Hz (-3 dB) for rich, punchy and undistorted bass with music, home cinema and gaming.

Sleek, high-gloss elements, rounded corners and a slender shape allows the US 2110/1 to blend in to any interior. Requiring a minimum of space, it’s easy to place.

The downward-firing bass reflex port and angled mains plug make it easy to place the speaker along a wall. Four resonance damping feet give the system a stable position and decouple vibrations from the floor.

The back panel includes a mono cinch input for connecting to a home cinema AV receiver as well as volume control and slide switch for regulating phase.

An auto level switch with three stages makes it easy to optimally adjust to the output level from various source devices, allowing the subwoofer to seamlessly switch between devices. An integrated limiter protects the system from overload and distortion.

Specifications

Centre Speaker CS 35 C
Centre Speaker CS 35 C
The CS 35 C center speaker is the acoustic equivalent of the CS 35 FR satellite speaker, but is set up for horizontal placement. In addition to its 19 mm high-range dome driver, it incorporates two 80 mm diameter mid-range drivers.

This ensures that human voices are particularly intelligible and faithful to detail, even when the listener isn't sitting in the optimal position (i.e. exactly in the middle). The speaker also radiates sound better thanks to a convex front plate.

The loudspeaker is delivered with a cradle, but can also be mounted on the wall. The CS 35 C is not offered individually, but only as part of a Consono 35 set.

Mono-Subwoofer US 2110/1 SW
A 20 kg bass cabinet creates the ideal conditions for the powerful integrated amplifier (125 watt rms power) and a larger than average 250 mm diameter woofer.

Teufel's legendary subwoofer expertise give you a 40 Hz (-3 dB) low end for full-bodied and accurate bass. Music, home theater and games - everything sounds deep and rich.

Rounded edges, slim design and a glossy finish make this subwoofer discrete and elegant. Minimal space requirements mean it can be placed anywhere in your interior.

The down-firing bass reflex principle and the angled, recessed plug allow the subwoofer to be position directly on a wall; four resonance damping feet ensure secure footing and decoupling from the floor.

The RCA connectors for a home theater AV receiver are on the rear, along with the volume control and a phase slide switch.
A three-level auto-switch ensures optimum output levels on the various devices. This ensures the subwoofer is always perfectly in sync with the rest of the system. An internal limiter protects against overloading and distortion.

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.


Can I operate the 5.1 set using a 6.1 or 7.1 receiver?
Yes. All Consono systems are suitable for connection to any conventional AV receiver – regardless of whether they are configured for 5.1, 6.1 or 7.1 systems. When connecting a Consono set to a 6.1/7.1 receiver, leave the rear-center terminal(s) unconnected.
Can I use my Consono system to listen to music?
Of course! All of the Consono variants play music from CDs just as well as they play home cinema sound from DVDs. The Consono systems are a top-quality replacement for old stereo speakers.
How do I best set up the Consono's subwoofer?
The Consono subwoofer can be placed anywhere without influencing the set's other loudspeaker. Ideally it is placed on the direct line between the two front satellites. A distance ratio of 1/3 to 2/3 generally brings about good results.
How do I best set up the Consono front satellite speakers?
The front loudspeakers of the Consono sets are best set up based on the traditional stereo model (distance to listener = distance between left and right speaker).

Optional speaker stands or wall mounts are perfect for this task. Using Teufel speaker stands automatically ensures the satellites will be positioned at their optimal height. Wall mounts make it possible to position the speakers vertically or horizontally. When placing the speakers on walls or shelves, the rule of thumb is that a height between 80 centimetres and 1,60 metres should be chosen. If the speakers need to be placed outside of this range, they can also be angled up or down towards the listening position. What's important is that the center and front loudspeakers should be positioned in a straight line or arranged around the television to form a slightly concave line.
Do I absolutely need an AV reciever to use Consono 15, 25 and 35?
Yes.
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.
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.
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.
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!
Der Subwoofer spielt nicht – was kann ich tun?
1. Falls die Power-Diode nicht leuchtet:
Tauschen Sie die neben dem Netzschalter befindliche Sicherung aus. Falls die Power-Diode danach nicht leuchtet, wenden Sie sich bitte an unseren Service. Falls die Power-Diode danach leuchtet, aber kein Ton zu vernehmen ist, verfahren Sie bitte wie unter Punkt 2. beschrieben.

2. Falls die Power-Diode leuchtet:
Drehen Sie den Pegelregler Level am Subwoofer auf »Minimum«, ziehen das Subwoofer-Cinchkabel am Verstärker ab, drehen Level vorsichtig hoch und berühren den Cinch-Heißleiter des Cinch-Kabels (innen) mit dem Finger. Ist nun ein Brummen oder Knacken zu hören, liegt der Fehler beim Receiver oder seinen Einstellungen. Bleibt der Subwoofer stumm, wenden Sie sich bitte an unseren Service.
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.
