Bosch LC5-CBB Back Box for LC5 Ceiling Loudspeakers

The LC5-CBB is the sealed back box for the Bosch LC5 2 inch ceiling loudspeaker. It protects the rear of the driver from dust and dripping water and makes the unit vermin proof.

It also prevents sound travelling through the ceiling cavity into adjacent areas, which is what keeps a small zone from bleeding into the room next door. The moulded box is white and weighs 41 g, matched to the compact LC5 housing.
