The Adastra BCS65S is a premium 6.5″ in‑ceiling speaker pair, ideal for both domestic and commercial installations. One speaker features built‑in Bluetooth 5.0 connectivity, allowing seamless wireless streaming, while the companion unit acts as a passive slave--perfect for multi‑room audio setups and neat, integrated sound solutions.
Constructed predominantly from durable ABS plastic, the BCS65S speakers are lightweight (1.91 kg per pair) but strong, and designed for long‑term reliability. The rubber‑edged polypropylene woofer and 12 mm neodymium dome tweeter deliver clarity and resilience. Frameless magnetic grilles sit flush with ceilings, and dog‑ear clamps ensure a clean aesthetic. The in‑line DC power brick is compact and easy to conceal.
