AtlasIED BT720-4 Series 4-Inch In-Ceiling Speaker Packages

The AtlasIED BT720-4 and BT720-4-T47 are high-performance 4-Inch in-ceiling loudspeaker packages designed for commercial paging and background music (BGM) applications. Both models feature the renowned AtlasIED FC104 high compliance loudspeaker, delivering full-range voice and music reproduction with wide-angle sound dispersion to provide excellent coverage with fewer speakers in distributed audio systems. Each package includes a factory-mounted dual-voltage transformer and grille, ready for efficient installation and reliable audio performance.

The BT720-4 variation boasts an attractive white finish and offers a broader range of power taps, including a low .25 watt setting for fine volume control. It is ideal for applications where aesthetic integration and flexible power options are critical. In contrast, the BT720-4-T47 emphasizes ease of installation with its torsion spring grille and patented EZ-Mount support system designed for suspended ceiling tile installations. This model provides power taps starting at .5 watt and is optimized for quick, secure mounting, making it perfect for fast-paced job sites.

Choosing between the two depends on your specific project needs: opt for the BT720-4 when a white finish and the lowest power tap are required, or select the BT720-4-T47 for streamlined installation convenience and EZ-Mount compatibility.
