Description

The Adastra BC4-W is a pair of 4 inch two-way background speakers built for indoor commercial use. Each speaker has an ABS enclosure with a powder coated steel grille, so they hold up well in shops, cafes, offices and other spaces that need steady, everyday sound. They come supplied in pairs, ready to run from a stereo amplifier.

Mounting is straightforward. Each speaker includes an adjustable steel bracket for wall or ceiling surface mounting, and there are M6 screw sockets if you prefer to fix them that way. The main drivers use coated paper cones for full low and mid-range frequencies, which suits both music playback and clear voice announcements. With a standard 8 Ohm impedance, they work with most common amplifiers without any special matching.

One thing to note: connecting leads (speaker cable) are not supplied, so you will need to add your own to suit the run between the amplifier and each speaker. The BC4-W is finished in white, and the same model is also available in black if that fits your room better. These are an industry standard choice where you want a tidy, reliable pair of background speakers that blend into the wall or ceiling.
