The SM63TEN is a premium 6.5-inch, 2-way surface-mount loudspeaker system engineered for superior audio performance in commercial installations. EN54-24 certified, it meets the stringent requirements for voice alarm and emergency communication systems while also providing excellent music and paging clarity. Each loudspeaker features a 32-watt 70V/100V transformer with screwdriver-adjustable taps, as well as an 8Ω bypass option for direct-coupled applications, making it highly adaptable to distributed audio systems.
Constructed with reliability in mind, the SM63TEN features a durable weather-resistant enclosure in white, with UV-stable PC/ABS housing, a powder-coated aluminum grille, and brass hardware inserts. Its 6.5-inch water-resistant composite woofer and 20mm ferrofluid-cooled dome tweeter deliver rich, full-range sound with smooth frequency response and optimized speech intelligibility. With a 120° conical coverage pattern, these loudspeakers ensure wide and even sound distribution, while the PolyGuard protection circuit safeguards the tweeter from harmful transients for consistent, long-lasting performance.
Sold as a matched pair in white with heavy-duty "C" mounting brackets included, the SM63TEN combines elegant aesthetics with rugged construction and professional-grade sound. Backed by a five-year warranty, these loudspeakers are the perfect solution for schools, houses of worship, retail spaces, restaurants, and corporate environments where high-quality sound and clean, unobtrusive design are essential.
