Description

The Adastra SL5 ceiling speaker pair offers a perfect balance of performance and subtle design. Featuring a 5.25" hi-flex polypropylene woofer and a 0.5" mylar dome tweeter, it delivers smooth, accurate sound with extended frequency response. The 2-way crossover ensures clarity across lows, mids, and highs, making it suitable for background music, paging, or home audio systems.

With a 160° dispersion angle and flared baffle, the SL5 provides wide and even coverage, ensuring consistent audio throughout the room. Installation is simple using three “dog-ear” clamps for secure ceiling mounting, and gold-plated spring terminals guarantee a reliable connection.

Supplied as a pair, these slimline ceiling speakers are ideal for retail, hospitality, office environments, or residential use where a sleek, low-profile audio solution is required. Their discreet design integrates easily into ceilings, offering powerful performance without drawing attention.
