LBC 3095/15 Pendant Sphere Loudspeaker
▶ Suitable for speech and music reproduction
▶ Simple power setting
▶ 5 m fixed connection cable
▶ Splash-waterproof type
▶ Robust self-extinguishing ABS enclosure to UL 94 V0
▶ Complies with international installation and safety
regulations
The LBC 3095/15 is a pendant sphere designed to be
suspended from the ceiling via its connecting cable. The
pleasing shape and neutral color make the pendant sphere
models interesting architectural features in their own right.
Functions
The pendant sphere is splash waterproof and suitable for
outdoor use and in environments with high humidity levels
such as swimming pools.
Their excellent sound spread makes them ideal for use in
buildings with high ceilings such as hypermarkets and
superstores.
The enclosures are made from high-impact selfextinguishing
ABS (according to class UL 94 V0) and are
colored off-white. The pendant sphere is designed to be
suspended from its color-matched connecting cable (easy
to shorten for desired height). A cable clamp and ceiling
cover are supplied.
They are not recommended for use in windy environments.
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.
All plastic parts are manufactured from self-extinguishing
high-impact ABS material (according to UL 94 V0). In
common with all Bosch products, care is taken to meet high
safety standards. These sound projectors comply with all
the relevant safety and installation regulations of EN 60065.
