Invisible audio for your ceiling. The CS-0506 is a 5-inch flush-mount ceiling speaker that provides gentle, even sound coverage. Engineered from high-class, shape-retaining steel, its ultra-lightweight 0.7 KG body and built-in mounting clamps make installation in drop-ceilings a matter of seconds. Ideal for elevators, office corridors, and boutique stores where aesthetics dictate that speakers should be heard, not seen.
