The LHM 0606/xx is a general purpose, 6 W, cost­effective ceiling loudspeaker. The /00 version is screw
mounted and the /10 version is clamp mounted into

Functions

An economic flushing-mounting ceiling loudspeaker is
available for general purpose applications. This full
range loudspeaker is suitable for both speech and
music reproduction in shops, department stores,
schools, offices, sports halls, hotels and restaurants.
The speaker assembly consists of a single-piece, 6W
dual cone loudspeaker and frame, with a 100 V,
matching transformer mounted on the back. A circular
metal grille is an integrated part of the front. The
appearance and neutral white color has been selected
to be unobtrusive in virtually all interiors.

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

u Simple power setting

u Unobtrusive in virtually all interiors

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.
