The LC4 Ceiling Loudspeaker Range can be used for a
wide variety of ceiling environments. They provide
excellent speech and music in indoor public address
applications. New CosCone driver technology, used in
this range, stands for delivering outstanding sound
quality from a small sized unit. It ensures a wide and
equal spread of all octave frequencies and eliminates
high‑frequency beaming. Fewer loudspeakers are
needed to cover a given area, and the noticeable
“fading” that can occur as a listener walks from one
loudspeaker to another area is eliminated.
The LC4‑UCxxE ceiling loudspeaker is a light and
compact unit with an unobtrusive, neutral designed
front grille. The range offers a choice of three
loudspeakers distinguished by input power of: 6 W,
12 W and 24 W with the same wide opening angle,
ensuring a wide and equal spread of the important
frequency octaves for speech intelligibility and music
clarity. The LC4 range also includes a back‑box and
metal fire‑dome.

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
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.
