Description

The Adastra SL6 is a slimline 6.5" ceiling speaker pair designed to deliver high-quality audio while remaining discreet and stylish. Featuring a hi-flex polypropylene cone woofer and a 0.5" mylar dome tweeter, it offers full-range sound with extended low-frequency response and detailed high-frequency reproduction. An efficient 2-way crossover ensures smooth audio balance, making these speakers suitable for both music and speech reinforcement.

With a wide 160° dispersion angle, the SL6 provides excellent sound coverage, while its flared baffle design enhances clarity throughout the listening area. Installation is quick and simple thanks to three “dog-ear” mounting clamps, and the gold-plated spring terminals ensure secure, long-lasting connections.

Supplied in pairs, the SL6 is ideal for commercial and residential use, including restaurants, retail spaces, conference rooms, and home audio setups. Its understated profile allows it to blend seamlessly into ceilings, offering powerful sound performance without compromising on aesthetics.
