The AtlasIED SD72 is designed for commercial audio contractors and systems integrators who need a reliable, distributed-audio ceiling speaker with built-in 25V/70.7V transformer capability. Its curvilinear, treated paper cone with a 1" copper voice coil on a black anodized aluminum former delivers consistent, low-distortion reproduction across the speech and music range — the same sonic signature that contractors familiar with the AtlasIED C-Series will immediately recognize, simplifying specification and commissioning.
In distributed audio environments such as retail spaces, houses of worship, hospitality venues, and corporate facilities, the SD72's transformer tap selections from 0.25 to 5 watts give system designers precise zoning control over coverage levels without additional attenuation hardware. The 105° dispersion angle supports wide, even coverage from standard ceiling heights, reducing the speaker count needed to achieve uniform SPL across a room.
The SD72 is UL 1480 and UL 2043 listed, making it suitable for plenum-rated ceiling installations where code compliance is mandatory. It mounts to a wide range of AtlasIED round and square baffles and enclosures, giving integrators flexibility to match architectural requirements without compromising system performance. Each unit ships individually packaged, supporting efficient job-site stocking and phased ordering on larger projects.
