I have a shape in my listening room as dampers. No drivers, control, etc. Just dampers. Looks great. Improves the sound. Uses no power.π
Slip a BeoLit 15 in the corner, cover it in acoustic cloth, invite your friends round, tell them the Shape has got a magic processor which throws the sound directly and accurately from the wall to the very corner of the room - then sit back and drum your fingers in satisfaction as they all nod sagely.
