Bose Professional Bose EdgeMax EM90-LP Low-Profile Loudspeaker

The EdgeMax EM90-LP is the low-profile version of Bose Professional's EdgeMax ceiling speaker, built around a 5.25-inch woofer and a 1.3-inch compression driver in a two-way passive design. Bose's patented PhaseGuide technology throws sound across the room from an edge or corner mounting position instead of the center of the ceiling, which is what lets the EM90-LP hold even coverage from an off-center placement other ceiling speakers can't.

It is finished in paintable white (similar to RAL 9003) to disappear into a finished ceiling, and its shallow 3.9-inch enclosure depth clears plenum spaces that a deeper woofer can't fit.
