German company Concrete Audio have designed a collection of wall mounted speakers that are made from concrete, wood, or a custom design, that allows them to look more like art hanging on the wall rather than a speaker.
The F1 Speaker has 41 electrodynamic mini-speakers that act like one large membrane, and allow for a total depth of only 32 millimetres, making ideal for hanging on the wall.
The wall-mounted loudspeaker is wireless, allowing for music to be streamed via smartphone, tablet or streamer. Due to it being no thicker than a picture frame, it would be suitable for small spaces, offices and it can be customized with individual motifs and finishes.
