The Bosch line of large premium loudspeakers consists of two sizes; 12” and 15” models. All models feature a two‑way loudspeaker in a molded ABS VO enclosure. The loudspeakers have a 1” compression driver coupled to an impedance transformer with constant directivity characteristics and a direct radiating 12” or 15” loudspeaker.
A self-restoring protection device protects the high‑frequency driver against incidental overload. The transformer accepts signals between 40 Hz and 22 kHz at 100 V or 70 V.
The LB3‑PC250 features a 12”woofer and 1”exit compression driver. The premium loudspeaker is fitted with a specially designed horn that provides constant coverage independent of frequency. The handle locations and position of rig‑points are placed to make the loudspeaker easy to carry and align when installing.
There is an integrated pole mount on the bottom of the cabinet and a weather-resistant steel grille. All screws and bolts are stainless steel or treated to resist rust. The cabinet has been designed to provide the possibility of mounting the loudspeaker close to a side wall or on the floor. The enclosure features high dampening, is impact resistant and weather proof (sheltered).
Suited for locations where high sound pressure, wide‑band audio is needed and where there is no mains power or where active loudspeakers are not desired, like outside applications or applications where the benefits of the 100 V technique comes into play like easy connection of multiple speakers and long cable runs.
The speakers are weatherproof (IP44, able to be mounted sheltered outside).
