Description

The Bosch LC3-CBB Back Box protects the rear of the loudspeaker from dust, falling objects, makes the unit vermin proof and prevents sound traveling via the ceiling cavity to adjacent areas. The back‑box is assembled with the loudspeaker by means of a snap‑in construction and has knock‑out
holes (11mm) for two rubber grommets (standard supplied) and for two cable glands (20.5mm).

The optional back‑box LC3‑CBB fully protects the loudspeaker from dust, falling objects and prevents sound traveling via the ceiling cavity to adjacent areas. The loudspeaker frame, grill and back‑box are manufactured from self‑extinguishing ABS according to UL 94V0.
