Description
The Adastra BG5A-W is an active stereo speaker set for indoor background music and smaller PA jobs. It comprises an active main unit and a passive satellite speaker, joined by the supplied 3m speaker cable. Both cabinets are moulded ABS with a powder-coated steel grille, and each houses a 5 inch (125mm) full-range driver with a reinforced paper cone. Rated output is 2 x 20W RMS, with a frequency response of 100Hz to 20kHz and 85dB sensitivity at 1W/1m.
Connection is straightforward. You feed audio into the main unit via L+R RCA phono sockets or a 3.5mm stereo jack, both at line level, so a phone, laptop or mixer plugs in without fuss. The main unit carries the on/off switch and a rotary volume control. Power comes from the included 12Vdc 3A in-line mains adaptor, which connects through a 5.5 x 2.5mm DC jack. This low voltage setup keeps installation safe and simple, with the mains adaptor sitting on a Figure 8 (fig.8) lead.
Each speaker measures 227.5 x 156 x 152.5mm (HxWxD) and the set weighs 3.274kg. Wall mounting brackets and hex screws are supplied, with magnetic covers for a tidy finish or standard screw caps if you want quicker fitting and angle adjustment. The white finish suits shops, cafes, offices and reception areas where you need clear background sound without a large system. It is a practical, cost-effective choice for anyone wanting stereo audio from a compact pair.

Frequently Asked
What inputs does the BG5A-W accept?
The active main unit takes L+R RCA phono or a 3.5mm stereo jack, both at line level. That covers most phones, laptops, media players and mixer outputs.
Does it come with everything needed to install?
Yes. The set includes the 12Vdc 3A in-line mains adaptor, a 3m speaker cable to link the two units, wall brackets and both hex screws with magnetic covers and standard screw caps.
How powerful are the speakers?
Each speaker delivers up to 20W RMS, giving 2 x 20W in total. They use 5 inch full-range drivers with a 100Hz to 20kHz frequency response.
Is one speaker powered and the other passive?
Yes. The main unit is active and holds the amplifier and controls, while the satellite is passive and connects to it via the supplied speaker cable.
Can I angle the speakers on the wall?
Yes. Using the standard screw caps allows angle adjustment during a quicker install, while the magnetic covers give a neater fixed finish.
What power supply does it need?
It runs on low voltage 12Vdc at 3A via the included in-line mains adaptor, which connects to the main unit through a 5.5 x 2.5mm DC jack.
