Bose Professional EdgeMax EM90 Premium In-Ceiling Speaker (White)

The Bose 778844-0220 is a premium loudspeaker that installs flush with the ceiling and brings Bose Professional sound to commercial and architectural spaces. It provides coverage that is both wide and intelligible, yet the hardware stays out of sight.

Because the EdgeMax EM90 is designed for placement near the junction where the wall meets the ceiling, a single unit can cover areas that normally require several conventional ceiling speakers. This approach helps designers lower hardware counts and simplify wiring.

Inside the enclosure, a high-frequency compression driver works with patented PhaseGuide technology to project speech that remains clear and music that retains nuance. Listeners near the front and those closer to the back hear the same consistent tonal balance.

The speaker fits naturally in retail stores, restaurants, hotel lobbies, corporate meeting rooms, and houses of worship, anywhere an owner wants premium audio without visible surface-mount boxes. The white finish blends with ceiling tiles, so the room keeps a clean look while guests enjoy Bose quality.
