Bosch LBD3904-L 6W Corner Cabinet Loudspeaker

The Bosch LBD3904-L 6W Corner Cabinet Loudspeaker is specially engineered for installations where conventional wall speakers may not be practical. Designed to be mounted neatly in room corners — either between two walls or between the wall and ceiling — this speaker offers efficient sound coverage with minimal visual intrusion. Its angled front baffle improves sound directivity, ensuring clear voice announcements and pleasant background music throughout the listening area.

Constructed from robust MDF (Medium Density Fiberboard) and finished with an easy-to-clean vinyl coating, the LBD3904-L provides long-term durability while maintaining a professional appearance. The ABS front panel features a premium woven cloth grille, available in black or white, blending smoothly with modern interior designs.

Bosch LBD3904-L 6W Corner Cabinet Loudspeaker Installation is fast and secure thanks to two integrated keyhole mounting brackets on one side of the cabinet. On the opposite side, vibration-absorbing bushes ensure stable positioning and reduce unwanted resonance. This smart mounting arrangement makes the speaker ideal for discrete placement in tight or unused architectural areas.

Bosch LBD3904-L 6W Corner Cabinet Loudspeaker includes a 4-pole push-in terminal block, making on-site wiring simple and reliable. A built-in 100V line matching transformer provides selectable power levels:

• 6W (Full)

• 3W (Half)

• 1.5W (Quarter)

This flexibility allows installers to adjust output volume based on room size and distributed audio system design.

As with all Bosch loudspeakers, the LBD3904-L undergoes rigorous testing — 100-hour rated power endurance according to IEC 268-5 PHC standards — ensuring consistent acoustic performance and long service life even in continuous-use environments.

Offering space-efficient installation, elegant design, and trustworthy sound quality, the Bosch LBD3904-L is an excellent solution for commercial and institutional public address systems.
