A wall-mounted speaker made with concrete eliminates vibration, while 41 electrodynamic mini-speakers output a wall of sound.

Concrete Audio’s moniker should make it evident the German-based audio company’s faith lies with neither wood nor ceramics, but with the mixture of ce­ment, water, and sand. The company’s F1 wall-mounted loudspeaker resides somewhere within the overlap of a Venn diagram between audiophile and architectural.

The immediate and obvious question that arises amongst the layman of course is, “Why concrete"” The short and simple answer: to eliminate unwanted vibrations.
A good loudspeaker housing should not vibrate, as modern drivers (the actual loudspeaker in the box) today render the full sound spectrum linearly. But if the housing itself does vibrate due to its construction or materials (wood, plastic), then those vibrations affect performance by amplifying or diminishing certain sympathetic frequencies within the sound spectrum.
Concrete’s unique properties ? it’s weight, irregular structure, and density – provide a medium untainted by the intrusion of unwelcome vibrations, the audiophile’s enemy. Each 32mm deep panel of concrete is embedded with 41 electrodynamic mini-speakers, a sort of beehive arrangement engineered to perform as a harmonious single source. The F1 is designed specifically for wireless playback, compatible with smartphones, tablets, or other streaming sources using...
