System overview
This range includes two circular type horns with aperture diameters of 355 mm (14 in) and 490 mm (20 in) and three driver units of 25 W, 35 W and 50 W. The assembly of the horn with the driver (separate ordered) results in an integrated horn loudspeaker. In this way the assembly of horn and driver, LBC3472/00 and LBC3478/00 is identical to the integrated horn loudspeaker LBC3482/00. The assembly of LBC3473/00 and LBC3479/00 is identical to the integrated horn loudspeaker LBC3483/00. The assembly of LBC3474/00 and LBC3479/00 is identical to the integrated horn loudspeaker LBC3484/00. The horns LBC3478/00 and LBC3479/00 are made from aluminum and the edges of the horns are covered with a PVC profile for protection against impact damage. The driver units LBC3472/00, LBC3473/00 and LBC 3474/00 have an aluminum inner cone and are provided with steel mounting brackets. The rear cover of the driver units is made from self‑extinguishing ABS (Acc. to class UL 94 V 0).
Both horns and drivers are finished in light grey (RAL 7035).

Notice
To reduce packaging volume and cost, the drivers as well as the horns are packaged 6 per box. The Minimum order quantity is therefore 6 drivers and 6 horns. Drivers and horns to be ordered separately.

Certifications and approvals
Quality assurance
All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 60268-5 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 improved reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and lessens the chance of failure or performance deterioration.
