Bosch LC1-CMR Ceiling Mounting Ring for LC1 Loudspeakers

The LC1-CMR is a ceiling mounting ring for the Bosch LC1 modular loudspeaker range. It carries the loudspeaker in a tile or plasterboard ceiling and spreads the load around the cutout.

Bosch lists it as the alternative to the LC1 ceiling mounting support bracket, so the choice comes down to what sits above the ceiling line and how much clearance the void gives you. The moulded ring is white, weighs 210 g, and holds its rating from -25 to 55 °C.
