The Bosch premium loudspeakers are full range passive loudspeakers for a wide range of applications where high output, wide controlled dispersion and wide frequency are required, as well as the flexibility of mounting inside and sheltered outside. 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. Typical uses include fixed installations in auditoriums, conference venues, community centers, theaters, areas of assembly, factories multipurpose halls and sports facilities. 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. - High‐quality music and speech reproduction - Weatherized, suited for sheltered outside use - Prepared for Bosch WLS, EOL and DMY pcb’s - Attachment points for (suspended) mounting, pole mount
