Bosch LBN9003/00-US 50W High-EfficiencyHorn Driver Unit

The LBN9003/00 50W high-efficiency horn driver is compatible with LBC3403/16 (10"), LBC3404/16 (14"), LBC3405/16 (20"), and LBC3406/16 (15 x 9") horns. A standard 1 3/8" screw thread is used for mounting the driver into the horns and is treated against corrosion. The driver unit includes a matching transformer to allow power tapping. This feature also allows impedance matching for different amplifier types.

A range of horns is available for this driver unit to allow tailor-made solutions for a variety of sound reinforcement applications. Three circular types (LBC 3403, LBC 3404 and LBC 3405 with diameters of 255, 380 and 510 mm respectively) and one rectangular type (LBC 3406, measuring 380 x 235 mm) are available. They are made from flame-retardant, high-impact plastic for high strength and low weight, and are finished in light grey.

All Bosch loudspeakers are designed to withstand and operate 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.
