Bosch LB1-BW12-D User Manual

Communications Systems | LB1‑BW12‑x Bidirectional Cabinet Loudspeakers

The LB1-BW12-x is a 12 W, cost-effective, bidirectional
loudspeaker for indoor use. The baffle design creates a
wide opening angle, making this loudspeaker very suitable
for use in long corridors. Keyholes at the rear provide
quick and easy wall mounting. The cabinet is available in
black or white.

The robust, solid MDF (Medium Density Fiber board)
enclosures are covered with a durable, easy-to-clean vinyl
in a choice of white or black. The ABS fronts are covered
with fine woven cloth in matching color.

The cabinets have two dual cone loudspeaker drivers,
mounted on an angled baffle, providing a wide opening
angle. This model is intended for use in long corridors,
such as in shopping arcades.

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.

tapping on the 100-volt, matching transformer in the
cabinet. It allows selection of nominal full-power, half-
