Bosch professional horn speaker system allows many different actuators to be installed in various horn speaker housings. The system consists of four horn speaker shells, three of which are circular speakers with opening diameters of 255, 380 and 510mm respectively; The other is a rectangular speaker with an opening size of 390 x 235 mm. The basic function exciter (ordered separately) is installed inside the horn speaker, and its connecting cable passes through the cable sealing plug on the cover plate and is connected out. This makes the speaker horn / exciter prevent liquid splashing, so it is ideal for outdoor sound reinforcement applications. Three types of exciters are available for speakers: 15 W, 30 W and 50 W (only for 100 V lines). Refer to separate data sheets. Horn speakers maximize the use of standard components of the modular concept. The screws securing the actuator are standard 1 3 / 8 inch threads (1 3 / 8 inch - 18 unef-2a). The exquisite design of the shell makes the loudspeaker unique and unique. Optional line / speaker monitoring board (and emergency connection adapter) can be installed on the inner surface of the cover plate. In addition, the speaker is additionally equipped with an opening for loop wiring (if a loop is used, the optional cable sealing plug PG 13.5 provided additionally must be used). These loudspeakers are made of high-strength flame-retardant plastic, which is light and strong. This durable material can not only prevent ultraviolet rays, but also resist the corrosive environment and most industrial chemicals. The color of the speaker (including the bracket) is light gray. The rugged steel mounting bracket (st 37 ‑ 2 DIN 1652) allows users to easily install horn speakers and adjust direction.
