  • 1Description

The Bosch LBC 15 W Rectangular Horn Loudspeaker outputs 15 W and provides highly accurate speech reproduction. The loudspearker's wide opening angle and powerful sound make it ideal for outdoor applications such as sporting events, parks, and swimming pools.


The horn features a direct connection to a 100 V line output and is finished in light grey (RAL 7035)
The horn is water and dust protected
The horn loudspeakers include a 100 V transformer with taps on the primary winding to allow different power settings. Nominal full-power, half-power or quarter-power radiation (in 3 dB steps) can easily be selected by connecting the amplifier output to the appropriate tap. A 2 m four-core cable is fitted to the horns. Each core is a different color, and is connected to one of the primary taps on the transformer
The horn loudspeakers are supplied complete with sturdy adjustable mounting brackets, allowing the sound beam to be accurately directed

Certifications & 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
