Description
The Adastra BC3-B is a pair of 3 inch background speakers built for indoor use in shops, offices, bars and other commercial spaces. They use a 2-way design with main drivers featuring coated paper cones, which gives full-sounding low and mid-range frequencies. That makes them a sensible choice for both music playback and clear voice announcements, so you get one set of speakers covering both jobs.
Each speaker has an ABS enclosure with a powder coated steel grille, a combination that stands up well to everyday knocks in busy rooms. They come with adjustable steel mounting brackets for wall or ceiling surface mounting, and there are M6 screw sockets if you prefer to fix them that way. The pair is finished in black, and a white version is also available in the range if that suits your setting better.
Impedance is a standard 8 Ohms, so the BC3-B connects easily to a stereo amplifier, and the speakers are supplied in pairs ready for left and right channels. One thing to note before you order: connecting leads (speaker cable) are not included, so factor those into your setup. These are industry standard units that do a straightforward job without any fuss, which is exactly what most background audio installs need.
