By Concrete Audio

Active compact loudspeaker made of concrete

The B1 is an active compact shelf speaker for straightforward enjoyment of music in its best possible quality.

The equipment with a full-range driver and two opposed midwoofers in an enclosed concrete casing devoid of resonance, enables the listener to experience extremely vivid and faithful sound.

Efficient Class-D technology and multifaceted adaptability via a digital signal processor (DSP) render the B1 a full-featured sound system with countless options, only to be completed by a source of your choice.
Connect the B1 fast and reliable with your music server, streaming device, tablet or smartphone, wired or wireless, and enjoy a concert atmosphere at home.

Concrete Audio casings are formed in a single pour, achieving solidity unreachable by a casing made of separate components joined together. Solid as a rock, concrete provides an ideal base for uninhibited driver expansion, free of interfering resonance.

You have the choice of au naturel, varnished, lacquered or real wood veneered.

In this type of production, color differences and small pore openings - also in comparison to the illustrations in the shop or catalog - are part of the usual nature of the material. In the case of concrete products, shading can also occur. These may include, among others, by influences such as temperature differences, humidity and concrete post-treatments or by impregnation. Such material properties belong to the typical or agreed upon nature of the products and do not constitute defects.**
