AtlasIED BT720-4-T47 4" In-Ceiling Speaker With 70V Transformer

The AtlasIED BT720-4-T47 is engineered for integrators and contractors deploying distributed audio systems in commercial spaces, houses of worship, hospitality venues, and corporate environments. By arriving factory-assembled with the loudspeaker, transformer, and baffle already mated, this package eliminates field assembly time and reduces the risk of wiring errors during high-volume installations.

At the core of the assembly is the AtlasIED FC104 high-compliance driver, a well-established performer in background music and paging applications. The 10-ounce ceramic magnet and damped cone deliver smooth low-frequency extension appropriate for voice intelligibility and ambient music reproduction across a wide listening area. A 135-degree dispersion pattern means fewer speakers are needed to achieve even coverage in open-plan spaces, directly impacting material costs on larger projects.

The torsion spring grille mount accelerates ceiling tile installations compared to screw-mount alternatives, and the dual-voltage transformer supports both 25V and 70.7V systems, giving system designers flexibility without requiring a separate transformer SKU. All B Series assemblies ship ready for installation, making them a practical choice for integrators managing tight project timelines and consistent performance standards across multiple zones.
