The SM63TEN is a high-performance 6.5-inch, 2-way surface-mount loudspeaker system designed to deliver outstanding clarity and reliability in professional audio installations. EN54-24 certified, this loudspeaker ensures compliance for voice alarm and emergency communication systems while also providing superior sound quality for music reinforcement and paging. Equipped with an internally mounted 32-watt 70V/100V transformer with screwdriver-adjustable taps, along with an 8Ω bypass setting, the SM63TEN integrates seamlessly into distributed sound systems of all sizes.
Constructed with durability and versatility in mind, the SM63TEN features a rugged, weather-resistant black enclosure made from UV-resistant PC/ABS, a powder-coated aluminum grille, and brass hardware inserts. Engineered for consistent performance, its 6.5-inch water-resistant composite woofer and 20mm ferrofluid-cooled dome tweeter deliver smooth, balanced sound across the full frequency range. The speaker's 120° conical coverage ensures even audio dispersion in both horizontal and vertical mounting positions, while AtlasIED's PolyGuard protection circuit safeguards the tweeter from harmful transients for long-lasting performance.
Packaged as a pair in black with heavy-duty "C" brackets included, the SM63TEN combines powerful output, rugged design, and sleek styling. Ideal for both indoor and protected outdoor applications, these loudspeakers are perfect for schools, retail spaces, restaurants, houses of worship, corporate facilities, and other environments where premium sound quality and reliability are essential.
