Cinebar Duett Power Edition review of www.av-magazin.de
Cinebar Duett Power Edition review of www.av-magazin.de Cinebar Duett Power Edition review of www.av-magazin.de
"a versatile, living room-friendly and therefore thoroughly recommendable audio solution for music and film sound"
www.av-magazin.de 19.12.2017
"Teufel's Cinema Duett is a modern sound bar with wireless music reception and wireless subwoofer."

"[…] This includes all the modern equipment details that improve sound, operation and versatility. Thanks to sophisticated technology, films, music and TV series can be enjoyed with rich sound - without having to fill the living room with speakers."

"Two tweeters and eight mid-range speakers in the sound bar ensure the best possible sound quality. […] Two mid-range drivers each radiate directly to the front and two to the side […] which provides a particularly spatial sound reproduction. The subwoofer CB 11 SW is used for bass frequencies."

"In the first listening test, the Teufel system impressed with good speech intelligibility. TV sound is expressive and clear. News speakers and dialogues sound very authentic. A real atmosphere is created when playing an action film via Blu-Ray. From now on, the sound bar with its impressive sound, defined by brilliant highs and richly detailed mids, is a delight. In the low frequency range, the compact subwoofer excels with astonishing power. Film sound effects with deep volume and noticeable thrust are transmitted into the listening room. When we activates Teufel's Dynamore technology at the push of a button, the soundbar offered a very effective spatial sound. This is characterised by an impressive acoustic depth and width, which effectively increased the film sound quality and enjoyment. And even when it comes to music, the Teufel set is completely convincing. Whether classical, jazz, pop or rock, thanks to the many sound presets, the system can be perfectly matched to individual listening tastes. And that leads to a first-class musical pleasure in our practical test."

"With the Cinema Duett Set, Teufel offers a powerful and space-saving audio solution. Thanks to Bluetooth, HDMI and dynamic surround sound, the Soundbar subwoofer system is a versatile, living room-friendly and therefore thoroughly recommendable audio solution for music and film sound."

"...also suitable for use as a small stereo system"
Computer Bild 25.03.2018
"[It] quickly becomes apparent that the Teufel device is also suitable for use as a small stereo system. In the test it didn't show any conspicuous discolorations and sounded very neutral and pure. In speech, it had a minimal tendency to create lisps. The subwoofer provided powerful bass. They stay clean to levels that the neighbours have been calling for a long time. Two 'Dynamore' modes can be activated by remote control. They use the side-mounted speakers for a more spacious sound."

"The combination of soundbar and subwoofer is equally suitable for action films and loud music, and the Teufel Cinebar Duett also masters the quietest sounds and clear reproduction of speech."

"...a more spatial sound"
Audio Video Foto Bild 05/2018
"The Berlin manufacturer has built additional speakers into the sides of the Cinebar Duett to create a more spatial sound. In total there are eight small woofers in the unusually shaped speaker, flanked by two tweeters on the left and right side of the front. Teufel does without a mid-range driver. The bass in the external subwoofer is processed by a speaker the size of a cake plate."

"At Teufel, 'Dynamore' mode leads to [...] wider sound."

"...practical features together with a good sound"
Widescreen 03/2018
"Available in all-black or partly white, the Cinebar Duett cuts a modern figure with its dumbbell shape and protruding end pieces and stands out pleasantly against the uniform, square design of many competitors. A large and easy-to-read display in the middle of the front panel makes it easy to read all settings. […] the Dynamore surround effect, [...] already elicits an extremely wide stereo sound from the small Cinebar One+, which is even more noticeable with the larger model. In film use, the sound bar [...] very engaging acoustics. […] audio playback [presents itself] as cinematic and powerful, but never noisy."

"Teufel delivers a great all-rounder with the Cinebar Duett. Here you get practical features together with a good sound - just right for users who don't want to save, but also don't need absolute high-end."

"...an uncomplicated and practical solution for better sound in the living room"
HiFi Test 03/2018
"[...] Soundbars like the Cinebar Duett are an uncomplicated and practical solution for better sound in the living room at home."

"There are two built-in mid-range drivers on the side of the soundbar, which radiate their sound outwards. While the stereo-widening mode already significantly increases the three-dimensionality, the ultra mode really provides a cinematic feeling. Action scenes come with the necessary force, also thanks to the good power reserves of the power amplifier. Dialogues remain understandable even in the original sound, even if you use the well-implemented cinema mode instead of speech, which provides great dynamics."

"Teufel's recipe for long-stroke drivers, a large diaphragm area and sufficient power is a great success with the Cinebar Duett. The soundbar works at a stable level and dynamically and convinces with great film sound. The simulated surround field also works wonderfully here. Especially with regard to the uncomplicated setup and handling of the set, this is a good alternative to classic 5.1 sets."

"...always delivers a convincing sound experience"
HiFi Journal 22.04.2018
"Teufel equips the Cinebar Duett with two different sound modes. You can choose between the 'Wide' and 'Ultra' settings for the Dynamore technology. The surround functions work well in movie playback, especially in the wide setting. The dispersion pattern is additionally shifted to the drivers mounted on the side and the sound backdrop is spiced up with a little more three-dimensionality."

"Acoustically, the Teufel Cinebar Duett has performed very positively with films and is flanked by a powerful subwoofer, which should feel most comfortable in rooms of up to 20m². […] The voice reproduction of the individual actors was clearly upgraded compared to the TV loudspeakers, so voices were equipped with the necessary fullness and real seriousness for the scene. Whether emotional moments or epic battles, the combination of soundbar and subwoofer always knew what to do and always delivers a convincing sound experience. […] When it comes to pure music reproduction, the tonality is solid and can certainly be used for one or the other party at a slightly higher room volume."

"The duo of Cinebar Duett and CB 11 SW wireless active subwoofer combine powerful and balanced home cinema sound with compact dimensions."

"combines compact dimensions with powerful and precise "home cinema sound""
www.lite-magazin.de 01.01.2018
"All controls for the most important functions are elegantly integrated onto the top panel of the Cinebar: switching on and off, volume control and source selection are possible directly on the device, very exemplary. For all other functions, the remote control comes into play, covering a much wider range of functions."

"A total of ten loudspeakers are installed in the Cinebar Duett according to the two-way principle. The eight mid-range drivers clearly outnumber the two tweeters. In view of this abundance of speakers, there is hardly any room left for a clean bass foundation, hence why it is outsourced. As you might have guessed, the CB 11 SW active subwoofer takes over the lower frequencies down to 33 Hertz. Not only does it benefit from its 165-mm woofer, but also from the bass reflex tube, which radiates down to the ground in accordance with the down-firing principle. The side-firing principle, which is often used as an alternative for subwoofers, uses the soundbar in this combo, which allows a total of four of its mid-range drivers to sit on their sides. In addition to the front-firing tweeters (in addition to the other four mid-range drivers, the two tweeters are also involved), the Class-D amplifiers also drive the mid-range drivers here. For example, the matte black beam uses the virtual surround sound technology 'Dynamore Ultra' to produce impressive surround sound without the need for external surround speakers. The sound emitted by the loudspeakers radiating at an acute angle is reflected by the walls instead. So if you use the appropriate sound modes 'Wide' or 'Ultra', the sound of the Cinebar Duett does not just emit directly to the audience, but is spread equally and pleasantly throughout the room."

"Thin sound is not in Teufel repertoire, but slim speakers are. The CB 11 SW Cinebar Duett, complete with wireless active subwoofer, is a prime example of these two aspects and combines compact dimensions with powerful and precise "home cinema sound"."

"a small soundbar, that is worth its price"
www.gameswelt.de 15.01.2018
"[…] The well-thought-out system shines with a very good, transparent and detailed sound, which is extremely powerful and yet well-balanced. The highs are clear and rich in detail, the mids are present, the bass is powerful, but never booming or humming. Even the four pre-settings are convincing, but we like it even better that we can also separately adjust highs, lows and subwoofer volume with the functional remote control. Another plus is the Dynamore sound widening technology, which gives the sound bar an incredibly wide and spatial sound."

"HDMI and TOSLINK are basically everything you need to connect TV and audio sources to a sound bar. Bluetooth connectivity is a welcome extra for streaming services, for example. […] All in all, it's a great sound bar that is worth its price and can be enjoyed for a long time."

"...convinces in terms of sound and offers a unique design"
Audiovison 02/2018
"The fact is that in order to create more volume for deeper basses, the Berliners have come up with a special "spoiler" design with enlarged sound chambers for the side mounted drivers. […] But the special design also has another trick in store: Teufel installed 2 drivers in each of the two slightly front-facing sides, which radiate sound to the walls from where it is reflected to the listening position. The so-called "side firing" principle is intended to be used in combination with Teufel proprietary "Dynamore" technology [...] which virtually expands the stereo panorama."

"The Teufel [...] Soundbar-Woofer combination impresses in terms of sound and offers a unique design."

The Cinebar Duett took second place with 72 points from a comparative test with a total of four test devices.

Note: Quotes refer to Teufel Cinebar Duett from a comparative review of 4 soundbars.

"a real spectacle"

„[…] The Cinebar Duett is concise in the upper mid- and treble ranges, providing the tweeter range with brilliance and clarity. […] The sound stage, which appears spacious and wide, is very appealing, even without Dynamore. […] The integration of the subwoofer in the first few minutes of the sound test series is an excellent feature. It reacts fast and subjectively without delay, hard bass strokes are produced emphatically and to the fore. […] All in all, the Cinebar Duett with the CSB 11 subwoofer manages to achieve [...] a very dense atmosphere with dynamic and full sound. The instruments have a well-structured effect and can be clearly differentiated from one another. […] The Cinebar Duett then plays all its strengths when used for watching films and presents a real spectacle. […] Individual elements are placed appropriately and the entire backdrop pleases with balanced naturalness."

"The mid-range drivers and tweeters alone are a bit bland, but when you add the subwoofer the sound is phenomenal [...]. In addition, there are the different sound modes like Movie, Music or Night [...]. The Dynamore technology already existed with the Cinebar One, but I have to say that here the spatial sound comes into its own even more than with its little brother."

"[...] The sound is really good. Depending on your needs, you have to fine tune the bass, and depending on what you listen to or watch, you have to change the sound. The bass is of course also a trademark of Teufel, because he really pushes like a devil. [...] A good recommendation [...] for people who want good sound - are not audio experts, but simply want to'feel' the music or the film [...]."

Help regarding this product
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!
My Bluetooth speaker produces a lesser quality sound with my Windows PC or laptop.
It could be that the speaker is connected as a device with speakerphone function. Please go to: settings menu > devices and printer > BOOMSTER (or other Bluetooth device). Right click on the device and remove the check mark next to the “speakerphone” option.
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.
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.
