Your choice: A modular set or all-in-one device

Use the included sides to combine the flat subwoofer and soundbar into a compact sounddeck. You can also mount the Cinebar 21 soundbar to your wall and stow the subwoofer under your sofa or sideboard – the choice is yours.

As a sounddeck
The Cinebar 21 soundbar and T 4000 subwoofer can be combined using the included side pieces. The resulting single device is a mere 13.2 cm high, allowing it to be used as a discrete pedestal for your television. The subwoofer’s well-braced MDF enclosure can easily accommodate even heavy televisions up to 60 inches wide.

For large, free-standing TVs, this is a great option.

As a soundbar
The Soundbar can be placed on a wall or on an included stand in front of the display. The subwoofer can be placed on a wall with the help of included wall mounts or slid directly under the sofa.

This is the perfect option for wall-mounted televisions.

Soundbar Cinebar 21 Mk2

Plug-&-play system
Connect your television, HD receiver and game console to the Cinebar 21 Flex and start enjoying immersive sound right away. You won’t require any additional cables or devices to experience the highest-quality playback with your TV.

Putting the sound in soundbar
No other soundbar in this price class packs as big a sonic punch as the Cinebar 21. How it does this is no secret: The Cinebar 21 simply offers more membrane surface area than other systems. In other words, it can simply push more air for higher, distortion-free levels.

The Cinebar 21 also plays back dialogue with incredible clarity. An authentic 2-way system with four large midrange drivers and two tweeters renders vocals and voices with natural, highly realistic tone and excellent detail.

Key features
  • An adjustable lip sync function ensures the perfect alignment of picture and tone
  • Two digital inputs for televisions and game consoles + stereo input for smartphones / MP3 players
  • An included remote makes it easy to switch between sources, regulate volume, subwoofer levels and more
  • Integrated wall mounts + soundbar stand make it easy to place the system in any living room

Dolby Virtual Speaker
Dolby Virtual Speaker is a technology that creates a surround sound experience from two separate speakers, in this case the left and right side of the Cinebar 21 soundbar. By cleverly adjusting the sound mix and sound signatures of each channel, the listener perceives a sound that seems to fill the room. Two different modes allow the listener to adjust playback to his or her preferences. For music in stereo, Dolby Virtual Speak can be simply switched off.

Premium flat active subwoofer
The T 4000 SW bridges the divide between easy room integration and mega bass playback. An incredibly flat enclosure makes it easy to place the T 4000 where it won’t get in your way. That small space behind the sofa or coffee table is enough. In fact, the T 4000 is so slender, it can even be positioned under most sofas, wall mounted or used to support your television. Its highly robust, reinforced MDF enclosure was designed to withstand the weight of conventional televisions making it the ideal sonic pedestal.

In spite of its highly convenient dimensions, T 4000 is driven by 250 watts for power to spare. A three driver system that is already successfully employed in Teufel’s highly popular System 4 THX model is used here as well. This ensures balanced playback based on THX standards and produces powerful, deep bass all the way down to 35 Hz for home cinema that makes you part of the action. Even very high levels are accompanied by very little distortion thanks to the long throw-drivers used.

The T 4000 is a universal subwoofer that can be combined with just about any home cinema set, even very high-performance models. This means the T 4000 is perfect for accompanying surround speakers or for giving an already complete 5.1 set an extra boost.

Help regarding this product
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.
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.
