The perfect entry into the world of audiophile-grade speakers at an unbelievable price.

Tough little speakers that'll never let you down

This wonderfully designed PC speaker set takes up a mere 12.4 x 12.6 centimetres of space on either side of your screen. The loudspeakers’ identical construction ensures a full, harmonious tone, and 40 watts of power guarantees a strong sound that stays distortion free even at high volumes. Professional bi-amping technology provides the high and bass ranges with their own dedicated amplifiers for stronger overall levels and better bass response.

Connection features make the Concept B 20 extremely easy to use. Volume and tone regulators are placed near the microphone/headphone jack, and setting up the speakers is as simple as connecting the "Line Out" of your PC or notebook with the input at the back of the master speaker.

The Concept B 20 allows you to listen to music on your computer that's much more precise and with a richer bass than the average PC speaker can deliver. Its size and price make it the perfect starter set for burgeoning audiophiles or really anyone looking for great PC sound.

Concept B 20 review of Hardware-Journal
"A multi-dimensional soundstage"
Hardware-Journal
"The sound is characterized by consistent tone stability. A punchy and powerful bass comparable to the Motiv 5 or even the Concept D500 THX should not be expected. In the high ranges, they remain unusually stable and have a big sound for the price. The small enclosure size compared to other systems limits the lower frequencies, but the maximum is achieved in this case which, of course, contributes to the tone."

"The Power of Sound"
player.de 10/2011
"The PC loudspeaker set Concept B 20 from Teufel sets a new milestone in the development of desktop speakers! The B 20 produces a powerful and rich sound with a deep bass like no other set in this size (without a subwoofer!). The volume levels and sound quality can compete with much more expensive systems causing one to wonder at the amazing price under €100 for the fully active Concept B 20!  The design and features are perfect for gaming and PC use, including an input for headphones- perfect for gaming! Amidst all these benefits, the fact that the Teufel Concept B 20 also allows you to listen to really good music at your PC almost gets lost in the shuffle."

"The right solution at a reasonable price"
technikblog

“I’m very happy with the decision to purchase the Teufel Concept B 20. Not only does it fit in with my other devices aesthetically, it has a great sound that is perfect for my needs. Monitor speakers would have been the alternative, but they were definitely too expensive and take up even more room on the desktop. So whoever is looking for a good compromise between professional loudspeakers and normal PC speakers will find the right solution with Teufel at a reasonable price!”

"Sound Tuning"
Video Home Vision 09/2011
"It’s usually not possible without additional speakers. Which laptop or desktop PC is equipped with speakers that make gaming, music, or watching movies really enjoyable? The selection of external PC loudspeakers on offer is therefore large. Too often, however, small speakers the size of tin cans available for €20 are expected to pep up PC sound, but never really deliver. With the Concept B 20, the Berlin loudspeaker specialists Teufel present an affordable solution at just under €100 with proper sound. A 2-way system with a 10 cm large midrange/bass driver and a 2.5 cm tweeter is powered by a separate amplifier in the enclosure. 30 watts per speaker provide enough sound for PC users. At room volume, music sounds natural and transparent with a properly voluminous bass foundation."

Overall assessment: Good
Price/Performance: Very good

"The desktop revolution"
Digital Tested 08/2011
„The Concept B 20 really showed what it was made of in the listening test. The little speakers were able to create powerful levels even without a supporting subwoofer and evinced a clean and powerful impulse response. The integrated bass reflex vents laid down a convincing sound foundation that is exceedingly rare in speakers of this size.”

“Impressive sound at an astonishingly small price. Teufel hasn’t over promised with the Concept B 20 and indulges both movie and gaming fans with big sound for little money.”

Price/performance: Excellent
Overall assessment: Very good

Help regarding this product
Gibt es für das Verbindungskabel zwischen den Lautsprechern eine Verlängerung?
Leider nein.
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 Concept B 20 hums. What can I do?
First off, it's important to know that the Concept B 20 is an active speaker system. This means when it's turned on and connected to a source, but the signal source is not switched on, there's a so-called grounding issue, because both devices have different groundings. As soon as you turn on the signal source, however, the hum should disappear immediately or be significantly quieter and should no longer be audible even in quiet music.

If the humming consistently gets worse, it could be also due to a closed device, bad cables, a strong WLAN network or distortion in the power supply.

Please do the following so that the hum can be identified and located.

Check the signal cable by switching it out.

Connect the net cable to another electricity area (for instance, the bath/kitchen/bedroom).

If the problem subsides, it means that your power supply has a problem. This can, for example,  be caused by chargers. To find the source of the disturbance, disconnect all devices one after the other from the power supply. As soon as the hum disappears, the source has been discovered.

Please do not place a wireless router next to the Concept B 20.
