The Adastra C5D ceiling speaker is a versatile and professional-grade audio solution tailored for domestic, commercial, and AV environments. Featuring a 130 mm polypropylene woofer and an 18 mm ferrofluid-cooled silk-dome tweeter, it combines clarity, efficiency, and seamless installation.
Designed for main audio zones, surround sound systems, or remote fill applications, the C5D delivers exceptional sonic performance via its two-way driver design and adjustable tweeter. Its spring-loaded terminals and dog‑ear mounts ensure quick and stable ceiling integration, ideally suited for trade professionals, installers, venue projects, and homeowners seeking quality.
The C5D features a robust polypropylene cone with a rubber surround for punchy mid‑bass and a ferrofluid-cooled silk dome tweeter for extended high‑frequency clarity. The directional tweeter enables off-axis tuning without compromising rigidity. At just 0.85 kg, the speaker is light enough to minimise ceiling stress yet solidly constructed for lasting performance anywhere it's fitted.

In real‑world use, the Adastra C5D provides articulate sound well suited to voice reproduction, background music, home cinema, and PA applications. The adjustable tweeter offers tailored dispersion, delivering clean vocals or crisp musical detail without harsh highs. Its modest depth makes it ideal for suspended ceilings, while installation is swift and tool‑free.
For optimal results, pair with an amplifier delivering 20-40 W RMS into 8 Ω. This ensures ample headroom and prevents distortion at moderate listening levels.
