For reliable, intelligible paging and background audio in security and commercial installations, the AtlasIED SD72 8-inch dual-cone in-ceiling speaker delivers consistent performance contractors expect. This AtlasIED pro speaker pairs a high-sensitivity 97dB driver with a wide nominal frequency response (45Hz–19kHz) to reproduce clear voice announcements and full-range background music with low harmonic distortion. The factory-installed 25/70.7V line-matching transformer offers selectable taps from 0.25 to 5 watts, making zoned paging and distributed audio straightforward to design and deploy across monitoring, surveillance and paging networks. Built with a 10oz ceramic magnet, copper voice coil and treated paper cone, the SD72 provides dependable long-term operation and even coverage with a 105° dispersion pattern. ETL listed to UL1480 and NDAA compliant, the SD72 is suitable for code-driven applications such as voice evacuation, security paging and facility-wide public address systems.
