The LB1-UW12-x is a 12 W, general-purpose, cost-effective
loudspeaker for indoor use. Keyholes at the rear provide
quick and easy wall mounting. The angled front baffle
results in a better sound in the listening area. The cabinet
is available in black or white.
Functions
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 angled front baffle results in improved high frequency
reproduction in the listening area.
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.
Safety acc. to EN 60065
Installation/Configuration Notes
Three keyholes in the rear panel provide easy and quick wall
mounting. A convenient easy-to-use, 4-pole push-in terminal
block is present on the rear panel for on-site wiring. This
terminal block has provision for power tapping on the 100volt, matching transformer in the cabinet. It allows selection
of nominal full-power, half-power or quarter-power
radiation (in 3 dB steps).
