Description
The Adastra BG4T-B is a full-range, two-way background music speaker built for indoor or outdoor use. It pairs a polypropylene low frequency driver with a dome tweeter inside a moulded cabinet, giving you clear, even sound across a wide 120 degree dispersion angle. The clean-line styling keeps things understated on the wall, and the black finish blends into most settings without drawing attention.
With an IP54 rating, this speaker copes with dust and splashing water, so it works well in covered outdoor areas, patios and other exposed spots. It runs on either 100V line or 16 Ohm systems, giving installers flexibility across different setups. Spring terminals and a rotary volume tapping switch sit at the rear, protected from the weather by a fitted cover. The cabinet uses a moulded PP construction with an aluminium grille for durability.
Each speaker comes with a wall mounting bracket that adjusts laterally and tilts to several positions, so you can aim the sound where it is needed. The BG4T-B is supplied singly, letting you buy exactly the number you need for a given space. Between the accurate sound reproduction, the weatherproof build and the easy mounting, this is a practical choice for background music in shops, bars, gardens and similar areas. It suits both new installations and additions to an existing 100V line system.
