AtlasIED FC104T72 4" In-Ceiling Speaker with 4-Watt 25V/70V Transformer

AtlasIED FC104T72 4" Full-Range Speaker with LT-72 Transformer

The AtlasIED FC104T72 is a compact, full-range 4" (127mm) loudspeaker equipped with an LT-72 70V transformer, designed for professional paging, background music, and general signaling applications. Built in the U.S.A., this high-performance 10-watt speaker delivers smooth, extended frequency response and exceptional reliability for commercial sound systems.

Featuring a damped, high-compliance cone, the FC104T72 provides outstanding low-frequency reproduction and clear vocal intelligibility. Its wide 135° dispersion angle (-6dB at 2kHz) ensures even sound coverage across large spaces, reducing the number of speakers required in low-level distribution systems.

The speaker’s 10 oz. ceramic magnet with a flux density of 10,500 gauss offers consistent output and long-lasting performance. A factory-installed 4-watt, 70V transformer allows easy integration into distributed audio systems, while the dual-purpose mounting bracket supports both low-profile transformer mounting and torsion spring installation with AtlasIED grilles and baffles.

The FC104T72 is UL1480 listed for general signaling and UL2043 certified for use in air-handling spaces, ensuring safety and compliance in commercial environments.
