AtlasIED SM12CXT-B 12" Coaxial Surface Mount Speaker, Black
The SM12CXT-B is a 12" coaxial surface-mount speaker pairing a low-frequency transducer with a 1" compression driver exit, built for school auditoriums, gymnasiums, cafeterias, and church sanctuary sound systems that need real throw distance from a wall or ceiling mount. A curvilinear, treated-paper cone reduces distortion, and a built-in crossover network keeps the two drivers integrated without external processing.
The wood enclosure with metal grille ships in black, with a matching white finish (SM12CXT-W) for rooms that need the opposite look. Twelve quarter-inch inserts support overhead suspension mounting, and a 60-watt 70V transformer covers standard distributed-system wiring.
