Cinebar One+ review of SFT
Cinebar One+ review of SFT
"the mini device achieves a surprisingly voluminous sound for its size"
SFT 01/2018
"Teufel is well versed in the field of compact TV speakers and would like to demonstrate their expertise with the Cinebar One+. Externally, the soundbar, only 31 cm wide, with its black metal housing and red accents, looks quite chic in the style of the Berlin audio brand. A look at the back reveals the connection panel. This is equipped with an optical digital input (Toslink) and an HDMI input. Thanks to ARC and CEC technology, only one cable is required for TV, and volume settings can be made via TV remote. The supplied control unit also gives us additional options. In addition to the choice between the various sources, these include various sound modes, which include voice amplification and the Dynamore room sound. The latter in particular is highly recommended, as the soundbar spreads the stereo signal much more widely in this mode, without appearing artificial. Thus, the mini device achieves a surprisingly voluminous sound for its size. We are also impressed by the detail reproduction and the bass. This is taken over in the Plus version by the wireless subwoofer [...]."

"Teufel has once again developed and launched an almost perfect product"
www.game2gether.de 18.12.2017
"[...] Four speakers in the Cinebar One provide the perfect sound. Two of them are mounted directly on the front and the other two are one on each of the slightly slanted sides. The arrangement of the angled sides is intended to provide a better sound experience."

"A bass reflex cabinet is used for the subwoofer. Both the tunnel and the tweeter are enclosed in the base plate. Furthermore, the subwoofer has a built-in 90-Watt digital power amplifier, which ensures a good amount of pressure.”

"[...] It quickly became clear that the new Cinebar One+ with its decent bass and very neutral sound tuning was completely convincing. Especially when watching movies, one notices a clear difference in comparison to TV speakers."

"In the PC Games test, the Cinebar One also made a very good impression [...]."

"With the Cinebar One+, Teufel has once again developed and launched an almost perfect product, which is not only suitable for beginners. A solid and beautiful combination of soundbar and subwoofer. The whole thing is rounded off with a multitude of connection options."

"In terms of sound, we're clearly putting the Cinebar One+ in the fast lane, because there's really nothing to complain about here [...].”

"The workmanship has turned out very good as usual from Teufel products."

"If you're looking for a powerful soundbar with a subwoofer, you're definitely not going wrong with the Teufel Cinebar One+."

"... a great sound backdrop"
www.lite-magazin.de 18.03.2018
"The Cinebar One+ impressively proves that you don't have to compromise on a cinema atmosphere that brings movies to life even when space is limited. The extremely compact dimensions of the soundbar / subwoofer combination gain enormously in size and create a great sound backdrop thanks to Dynamore technology. But that's not all, the Cinebar One+ not only offers a very good price-performance ratio, but also a successful and modern design and a remarkably high level of user-friendliness."

"...a real little home cinema..."

"Connecting the Cinebar One+ to a TV set and operating the device is child's play - there could hardly be an easier and faster way to improve the TV sound. […] the sound system [plays] astonishingly spacious and clear, and the wireless subwoofer provides pleasant pressure in the lower pitches."

"The ultra-compact Cinebar One from Teufel is particularly suitable for smaller apartments, as it effortlessly expands your home TV set into your own small home cinema. As the Cinebar One+, it also features an active subwoofer, making it ideal for smaller rooms. The unbeatable price also makes the Cinebar One a real recommendation."

"the sound bar delivers a surprisingly voluminous sound with clear trebles"
e-media 02/2018
"Regardless of its size, the soundbar delivers a surprisingly voluminous sound with clear trebles. This is mainly due to the Dynamore Ultra technology: Teufel has built four full-range loudspeakers into the small cabinet, which deliver the sound in all directions and thus provide a virtual surround sound image."

"Since music and film without bass are only half as much fun, we recommend the Cinebar One+ set. In this version, the sound bar can unfold its full potential as it is supplied in a package with a wireless active subwoofer."

"If you usually only use TV speakers, you will have fun with the Cinebar One+. After switching to the sound system, you will notice a clear difference to the TV speakers, which you won't want to lose again. You can't expect the real cinematic feeling offered by a 5.1 home cinema system, but for its size and price, the performance is more than consistent."

Cinebar One+ review of Heimkino
Cinebar One+ review of Heimkino Cinebar One+ review of Heimkino
"highly recommended!"
Heimkino 12/1-2018
The 70mm high and only 110mm deep plastic casing houses a total of four full range speakers with 40mm cones. Two of them radiate to the front, and two more have been placed on the left and right side of the cabinet, extending the acoustic stereo stage and provide virtual surround sound. The Cinebar One can also be used as a sound system for the smartphone, because the soundbar can also receive music via Bluetooth (aptX). A handy, clearly arranged remote control makes the Cinebar One easy to operate, and various sound presets can also be called up."

"With a remarkably low frequency cut-off of 100Hz, the Cinebar One is a stand-alone sound system, but for true movie enjoyment, the soundbar's bass response is limited. That's why Teufel offers the Cinebar One+, a set including an active subwoofer. For a small extra charge, the CB11SW provides customers with a handy subwoofer that wirelessly take control of all the bass components of the Cinebar One and puts them in the spotlight. Thanks to its compact dimensions, the CB11SW can be placed in small niches and makes move nights way more fun."

"Connecting the Cinebar One+ to a TV set and operating it is child's play - you'd be hard pushed to improve TV sound in a faster or easier way."

"With the ultra-compact Cinebar One, a TV set can be easily and conveniently upgraded to a home cinema. Especially as a Cinebar One+ version including an active subwoofer, this sound system is a practical suggestion for small living rooms and a real recommendation due to its low price!"

"...the soundbar offers considerably more sound volume and punch than the usual speakers of current flat screens"
www.lowbeats.de 16.12.2017
"[...] For its minimal dimensions, the soundbar offers considerably more sound volume and punch than the usual speakers of current flat screens."

"But even as a sound card for Mac or PC the Cinebar One did a damn good job."

"Teufel is right to emphasise that the Dynamore Ultra technology behind it, developed in Berlin by Teufel, enables an astonishing surround sound. The surround method also helped stereo music in the test in such a way that we would actually always use it."

"[...] The Teufel Cinebar One is a really great product, but the Teufel Cinebar One+ with the additional subwoofer CB 11 SW is really awesome."

"With its powerful, contoured bass, the CB 11 SW active subwoofer fits in perfectly with the soundbar. The timing was perfect, the tempo was fast and synchronous [...]. With a low-frequency reproduction of this richness and quality, the devilish duo not only had a lot of fun, they also excelled with music playback. It didn't matter whether the sound was played via HDMI, Bluetooth or directly from the computer via USB.”

"[...] One thing is certain: both the Teufel Cinebar One and the Teufel Cinebar One+ are absolute highlights. And not only for the usual home cinema soundbar fans, but also for anyone who is looking for an affordable stereo system with a full, clear sound.”

Cinebar One+ review of Audiovision
"...small sound rocket"
Audiovision 01/2018
"When the Cinebar One is connected to the flat screen TV via HDMI cable and plays for the first time, there is confusion in the test room. Apparently another speaker is playing, the mini soundbar can never produce such a massive sound stage alone. Buy this little sensation actually can! You can use a separate button to activate stereo expansion. This is indeed recommended [...]. The speech intelligibility of the Cinebar One is excellent, voices is transported very cleanly and precisely. Even with fast classical pieces with different instruments, the Cinebar One works out the individual ensemble members exactly and goes along with every tempo, no matter how fast."

"A practical feature: the Cinebar One has an integrated USB sound card."

"As a small sound rocket for the living room, Teufel's Cinebar One soundbar ticks all boxes. The sound is impressive, the variety of connections and operation are top-notch."

"...recommended to everyone looking for a compact sound solution"
AV-Magazin 20.11.2017
“Soundbars and sound decks are becoming increasingly popular. To do justice to the growing trend, direct marketing manufacturers Teufel are therefore offering the new Cinebar One system. The soundbar, only 35cm wide and 68mm high, requires little space and therefore fits under any TV. It also offers wireless music reception and a range of of modern AV connections that make it easy to operate and integrate into home AV environments. The Teufel Cinebar One is an all-in-one sound solution that includes everything you need for audio playback. The extra portion of bass is provided by the Cinebar One+, which comes with an additional subwoofer[...]."

“[...] Since the Cinebar One system has a Dolby decoder, it is able to decode and playback multi-channel audio in addition to two channels. [...] If you want to use the soundbar as a computer loudspeaker, you can use the built-in USB-DAC. The wireless Bluetooth audio feed is very simple, whether you are playing music saved on the device, from online radio or via streaming services such as Spotify and Tidal. Integrating the subwoofer is also child's play."

“In our practical test, we were impressed by the decent bass and neutral tone tuning of the small soundbar. In contrast to TV loudspeakers, film dialogues, news bulletins and TV series, the sound is much better. Those who want to listen to music via the Teufel-System should choose the Cinebar One+ Set. [...] Then the Teufel set offers a decent bass that brings music and film sound to life."

“With the Cinebar One, Teufel shows that even very small audio systems can improve the sound of modern flat-screen TVs. With wireless music reception, extensive connectivity and an optional subwoofer, the Cinebar One is a top recommendation for anyone seeking an ultra-compact sound solution."

"You shouldn't underestimate the Cinebar One"
Video 12/2017
"... with a length of 35cm and a height of just under 7cm, the Berlin sound bar is really pretty small. But inside, there are four broadband loudspeakers installed, two of which radiate to the front and two radiate sideways, thus creating the largest possible sound field [...]. A bass reflex port on the back of the speaker amplifies the reproduction of low frequencies. [...] Thanks to Dynamore Ultra technology, you don't get an impression of its small dimensions, on the contrary. [...] When stereo widening is activated, the wow effect is really enhanced [...]."

"With the Cinebar+, you get a matching subwoofer with down-firing technology [...] After pairing with the Cinebar, the lower frequencies are trasmitted via the woofer."

"You shouldn't underestimate the Cinebar One. Despite its small dimensions, it fills small to medium-sized rooms with balanced sound. Thanks to aptX, it is also fun to use it as a Bluetooth speaker."

"The sound, workmanship and set-up are really impressive."

“[…] The Cinebar One itself has four 50mm drivers. […] two of them [are] mounted diagonally on the front and one on each side. […] There is also a small bass reflex port on the back. This ensures that the bass tones can escape from the cabinet and thus serve as support for lower frequencies."

“[…] the Cinebar One already sounds very good alone [...]. If I compare the sound and especially the wide sound image that the Cinebar One produces, I can say that I have not heard any other Bluetooth speakers with a similar size before. Even when used on its own, the bass is surprisingly good."

“The sound produced by the Cinebar One+ system is very good. Both the high and the mid tones are very clear. This also optimises the reproduction of voices, which are reproduced very cleanly and clearly. Together with the subwoofer, the basses come across very strongly.”

“[…] The sound, the workmanship and the set-up [...] really impressed me.”

“[…] Teufel Cinebar One+ is a great sound bar and subwoofer pair for those of you who want to enhance their poor TV sound without having to install an extremely large sound bar in front of the TV.”

“The Cinebar One is a good soundbar for students, teenagers, for in the bedroom etc. Basically for small rooms where you still want a good sound. Sound is at its best with a rich bass and good treble and yes, that's what the Cinebar One delivers. For such a compact speaker, the bass in particular is pleasingly good! The emission width is great, too, and it's easy to forget that the sound comes from a 35cm speaker.”

“The Cinebar One can also be used as a soundbar outside of the classic use thanks to its versatile connectivity options.”

"A great device"
www.gameswelt.de 07.01.2018
„[…] What makes the Cinebar One stand out, especially when paired with the subwoofer, doesn't have to hide behind the performance of much larger sound bars. This is above all due to the clever arrangement of the four speakers, which, thanks to the in-house Dynamore-Ultra technology, provide a surprisingly wide, clear and voluminous sound. The connection options also leave little to be desired, from Bluetooth with aptX to the USB connection, which means that the One can also be used as a PC speaker with an integrated sound card."

Help regarding this product
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.
How do you wirelessly connect the Cinebar One to the CB 11 subwoofer?
You can pair the Cinebar One with the CB 11 SW wireless subwoofer. When starting up, connect the devices to each other once as described below using so-called "pairing".
  1. Press and hold the SUB PAIRING button for five seconds. The operation LED will start flashing slowly in blue - the Cinebar One now automatically searches for a wireless subwoofer for approx. 60 seconds.
  2. Whilst the Cinebar One is searching for the wireless subwoofer, enable the connection by pressing the "pairing" button on the rear side of the subwoofer.
  3. After a short time both devices will connect and the subwoofer will take over the bass. Please note that the blue status LED goes out again after successful connection, but the connection remains active.

Retrofitting a subwoofer? See the compatible product here: Subwoofer CB 11 SW
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.
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.
Why is the Subwoofer CB 11 SW now called the T 6 Subwoofer?
This makes our subwoofer series easier to organize. There are now the T 6, T 8 and T 10 subwoofers. But don’t worry, only the name has changed, nothing else.
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.

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.
