For a concentrated orchestra rehearsal, the 11905 sound shielding element is ideal. It can be attached to backrests with a rod and reliably shields the sound of the person behind you. Ideally suited for König & Meyer orchestra chair 13430. The height, distance and even inclination are infinitely adjustable and can thus be adapted to individual needs. The screen can be used both concave and convex and is therefore an absolutely recommended and highly functional music accessory.
