The 6W white LBC 3018/01 Metal Cabinet Loudspeaker from Bosch delivers professional performance from a robust yet aesthetically designed metal enclosure. It is a loudspeaker suitable for indoor use in offices, schools, car parking, shopping centers, and in areas where vandalism is a potential hazard. The cabinets are equipped with a high-efficiency, dual-cone loudspeaker, offering a wide frequency range suitable for both speech and music reproduction.

The cabinet is designed for both surface mounting on walls as well as recessed mounting into brick or concrete walls. The back-box of the cabinet provides a selection of mounting holes, even for mounting onto U40 and MK installation boxes. The back-box has 2 knockout holes on the topside for 2 cable glands for loop-through connection. For extra convenience, a safety cord from the back-box lets the installer temporarily hang the front grille unit during installation.

The cabinet has a 3-way terminal block with screw connections suitable for loop-through wiring (including earth). The 4 primary taps are provided on the matching transformer to allow selection of nominal full-power, half-power, quarter-power, or eighth power radiation (in 3 dB steps).


This voice alarm loudspeaker is specifically designed for use in buildings, where the performance of PA-systems is subject to official regulations. It is designed for voice alarm systems, and is compliant with the EN 54-24 standard.

The loudspeaker has built-in protection to ensure that, in the event of a fire, damage to the loudspeaker does not result in failure of the circuit to which it is connected. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation.

The loudspeaker has a ceramic terminal block, thermal fuse, and heat-resistant, high-temperature wiring. The cabinet has a provision for internally mounting the line/loudspeaker supervision board (sold separately).

Certifications and Approvals

This loudspeaker is designed to withstand operating at its rated power for 100 hours in accordance with IEC 268-5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that the speakers can withstand 2 times their rated power for short durations.

This ensures extra reliability under extreme conditions, leading to greater customer satisfaction, longer operating life, and much less chance of failure or performance deterioration.
