Bosch LC1-CBB Back Box for LC1 Speakers

Keep your ceiling-mounted audio installations clean, compliant and acoustically isolated with the Bosch LC1-CBB back box. Designed specifically for Bosch LC1 loudspeakers, this pro accessory prevents sound traveling through ceiling cavities—improving intelligibility for public address, security and emergency voice alarm systems. The LC1-CBB is EN54-24 certified, providing the assurance required for life-safety and monitoring installations.

Constructed from durable white plastic, the back box protects the loudspeaker rear from dust, dripping water and falling objects, and makes the assembly vermin-proof for reliable long-term operation. Installation is fast and professional: the back box clicks onto the mounting ring and includes knock-out holes for two 11 mm grommets and two 20.5 mm cable glands, enabling neat cable management for surveillance, networked audio or PA cabling. Lightweight and purpose-built for the LC1 series, the LC1-CBB simplifies compliance and reduces rework in commercial, retail and institutional security projects.
