Functions
The sound projector features a very wide opening angle
(90 degrees) which means fewer units are required to
cover a given area. Its wide frequency range also results in
better speech and music reproduction, while the
directivity ensures that the sound is accurately projected
to where it is needed most.
The LBC 3941/11 sound projector is finished in an
attractive white color, and its unobtrusive appearance
complements today’s interior lighting. The color and
styling of the front grille matches an existing Bosch ceiling
loudspeaker (LBC 3951/11).

Certifications and Approvals
All Bosch loudspeakers are designed to withstand
operating at their 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 they can withstand two times their rated power for
short durations. This ensures extra reliability under
extreme conditions, leading to higher customer
satisfaction, longer operating life, and much less chance
of failure or performance deterioration.
The enclosures are made from high-impact self-
extinguishing ABS (according to class UL 94 V0).
