"A true recommendation" <br>Note: This test review is for the previous model

Loudspeaker recommendation: Teufel’s Concept B 20

The sound that the loudspeakers produce is strong and powerful, but still balanced. You can connect the speaker set to a normal stereo output on your mainboard and plug it into a power outlet. The compact set also cuts a good figure on any desk. Both boxes have an enclosure finished in a chic piano lacquer look and are made enitrely from synthetics. One of the speakers is equipped with dials for volume and regulating the bass.

The Concept B 20 set is a joy for the eyes and ears. [...] The loudspeaker’s sound and workmanship are a credit to the Teufel system.
A true recommendation [...]

"The Teufel Concept B 20 really has a lot to offer for a great price"
PC Magazine
Concept B 20 Mk2 SE review of Area DVD
Concept B 20 Mk2 SE review of Area DVD
"They’re able to forcefully sling electronic effects and sound elements at the listener and operate with good impulse fidelity and accuracy"
Area DVD 04/2014
“The two attractive looking small 2-way speakers look  […] good placed to the left and right of the PC monitor. A special feature is the slanted baffle which is not only a matter of style, but has acoustic optimizing advatanges [...] Naturally, connecting to a smartphone or portable MP3 player is also possible. [...]

In the front [...], a high-end metal grille covers the drivers [...] which also optimizes the frequency response for a natural sound preproduction. The possible listening range is broader which has the advantage that even if one is positioned in front of the speakers, a complete sound image can be appreciated. [...]"

"[T]he Concept B20 Mk2 [do…] a very good job which we noticed on the extremely precise and at the same time powerful bass as well as the vocal sections that were well integrated. You can really crank up the levels and both loudspeakers have no problems keeping up. They’re able to forcefully sling electronic effects and sound elements at the listener and operate with good impulse fidelity and accuracy […]"

"Small dynamic differences as well as electronic effects are wonderfully emphasized with both Concept B 20 Mk2 speakers. [...] Placed to the left and right of the PC monitor, both Concept B Mk2s are capable of really surrounding the listener with sound – no superficial, thin acoustic acoustic presentation is produced here, but rather an experience of true listener involvement [...]"

Conclusion

"With a pleasant look, a substantial and dynamic sound, perfect level stability and a fair price, the Concept B 20 Mk2 plays its way into the hearts of many PC users. [...] Compact multidimensional speakers with a nice look and compelling sound – for a fair price.“

Help regarding this product
Which speaker cables does Teufel recommend?
For smaller sets up to Theater 1, we recommend using the 2.5 mm² Teufel speaker cable for optimal sound quality if the required length does not exceed 15 metres.

For Theater 2 and larger systems, we recommend the Teufel cable with 4 mm² cross-section for the front/centre speakers, and the 2.5 mm² cable up to a length of 15 metres for the effect speakers.

Choose a higher cross-section for even greater lengths.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
Is it possible to combine speaker cables with different cross-sections?
To supplement missing cable lengths you can use speaker cables of differing thicknesses without acoustical differences - provided there are no extreme differences in the cross-sections.
Should I rather choose a fully active or a partially active speaker set?
It is compulsory to connect partially active systems to an AV Receiver. This supplies the five to seven satellite speakers with the necessary power. Only the subwoofer works additionally with its own amplifier. The investment in a new system is higher because of the AV Receiver, but the solution is also much more flexible. After all, you can connect several signal sources, such as a TV, satellite receiver, PC, game console and MP3 player to an AV Receiver at the same time.

Fully active set do not necessarily need an AV Receiver. The five to seven satellite speakers here are supplied with power by the amplifiers which are installed in the subwoofer in addition to the subwoofer power amplifier. This saves you the costs of a receiver, but it is usually only possible to connect one source to our fully active subwoofer.

Exceptions here are the Concept E2, the Concept E Magnum Digital, the Motiv 5 Digital, the Concept F, the LT2+R and the Concept S+R.

Naturally you can also equip the fully active systems with an AV Receiver at a later point. The connection is then equal to the partially active sets.
Can I set up the set in a different way to that described?
The recommended set-up information below represents the best possible arrangement for perfect multichannel playback in your home. Your available space, your partner or your furniture may not always allow you to arrange the speakers in the ideal manner. Try to meet as many of the requirements as possible.

Modern AV Receivers offer numerous options for compensating electronically for any compromises in the set up. Generally speaking, the following rule always applies: you can always use our recommendations as a basis for experimenting with what works best for you, acoustically and optically.
