Teufel's Consono series was specifically developed to facilitate an inexpensive entry into the world of surround sound. If you want to replace your current speakers with a home cinema sound system for countless hours of fun – or if you're just interested in getting a start with Teufel's peak-quality sound – then Consono is perfect for you. Every model in the Consono line guarantees an excellent price-to-performance ratio.
Capable of turning any small living room into a thrilling home cinema filled with gripping music and realistic sound effects, the Consono 15 is the most compact set of its series.
The key to a true surround sound experience is delivered by five identical wide-band satellite speakers. Small but powerful, these satellites cover the entire mid-to-high range frequency spectrum. The Consono 15 is well-balanced and precisely tuned, as is the case with all Teufel systems.
The Consono 15 satellites are shipped ready to be wall-mounted, but they are also perfect for free positioning using Teufel's M 50 P floor stand. Simply connect the satellites and subwoofers to your AV receiver or sound system and start enjoying great surround sound right away .
But Consono 15 isn't only shipped with satellite speakers of a noticeably high quality: it also has a tight bundle of deep-range power in its bass module – 100 watt RMS output from a 200 mm bass driver which goes down to 38 Hz.
A great start
Acoustically balanced, durable and capable of filling rooms up to 20 sqm with Teufel's hallmark sound, Consono 15 easily sets itself apart from competitors in its price range. You won't find this level of sound for a comparable price anywhere else.
The 150 Hertz mark is achieved through a 200 mm woofer with a 100 watt amplifier that delivers the hefty bass. Just what you need.
- Satellite Speaker CS 15 FCR (pc.)

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.
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.
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.
• 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.
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.
• 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.
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).
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.
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.
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.
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.
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.
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.
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!
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.
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.
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.
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!
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.
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.
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).
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.
