Active version of the BP-series weatherproof wall-mounted speakers with an internal amplifier and hard-wired 4-core cable for signal and power input. Each speaker can be driven by any 12Vdc power supply with 2A or more current capacity (e.g. 153.754UK) and accepts a mono line level signal input. A suitable alternative to active horn speakers where sound quality is paramount. These speakers can be operated in indoor or sheltered outdoor areas, thanks to the water-resistant polypropylene drivers and sealed cabinets. Designed for CCTV installations, simple background music systems or to extend an existing sound installation without adding further amplifiers.
