Communications Systems | LBC 3700/00 Horn Loudspeaker
The Bosch LBC 3700/00 Horn Loudspeaker features an
extended frequency range and high sensitivity which
makes it ideal for high quality speech and music
reproduction. The wide opening angle ensures even sound
distribution, so fewer horns are needed to cover a given
area.
Functions
The rectangular horn features a unique combination of a
re-entrant horn with two transducers, one for low- and the
other for high frequencies, resulting in breathtaking sound
clarity.
The horn is weather protected and can be used in areas
with high humidity. It is therefore suitable for outdoor
applications such as swimming pools, sports stadiums,
leisure parks, cruise ships, schools and train stations, as
well as for indoor public address. Finished in light grey
RAL 7035 color, the ABS horn is both stylish and
lightweight.
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.
