BOSE EM-90 Commercial and Ceiling Speakers

Bose Professional EdgeMax EM90 In-Ceiling Loudspeaker

The Bose Professional EdgeMax EM90 combines the output and coverage of large surface-mount loudspeakers with a discreet in-ceiling design. Featuring patented PhaseGuide technology, this 2-way system delivers powerful, focused sound from the room’s edges toward the center, providing uniform coverage and exceptional voice intelligibility across the entire listening area. Ideal for large, high-SPL spaces such as fitness clubs, performance venues, and houses of worship, the EM90 offers immersive full-frequency sound for both music and speech—even at high volumes.

Its 75° vertical and 90° horizontal coverage pattern makes it perfect for mounting near edges or corners, while the QuickHold spring-loaded mounting system ensures fast and secure installation. The magnetically attached grille allows easy access to wiring and tap settings, and the unit meets UL1480A and UL2043 safety standards for plenum-space installation.
