Atlas Sound BT720-4-T47 – 4" 70V In-Ceiling Speaker with Baffl...
Product Overview
The Atlas Sound BT720-4-T47 is a factory-assembled 4" in-ceiling speaker package for 70V distributed audio systems, combining the FC104 high-compliance loudspeaker with a 4-watt 70.7V transformer and T720-4 torsion spring baffle. This package is designed for commercial background music and paging installations where consistent, full-range audio coverage is required with minimal installation labor. The BT720-4-T47 is compliant with BAA and TAA requirements and carries cUL certification, making it appropriate for government, education, and corporate facility deployments.
Product Description
The BT720-4-T47 uses the AtlasIED FC104 4" high-compliance loudspeaker, a proven driver for voice and music reproduction in distributed constant-voltage systems. A 10 oz. ceramic magnet and damped high-compliance cone deliver solid low-frequency response with smooth, extended high-frequency reproduction. The factory-mounted 70.7V transformer provides power taps at 0.5, 1, 2, and 4 watts, allowing system designers to optimize load distribution across long cable runs. A 135° dispersion angle at the 2kHz octave band ensures wide-area coverage, enabling fewer speakers per zone without sacrificing intelligibility. The torsion spring grille design eliminates screw-mount installation steps, reducing labor time on large-scale projects. All components ship pre-assembled and are ready to install directly into standard ceiling cutouts. The BT720-4-T47 is suited for hotels, retail spaces, healthcare facilities, corporate offices, and educational buildings where a clean ceiling appearance and reliable audio performance are both required.
