Bose Professional Bose EdgeMax EM180-LP Low-Profile Loudspeaker

The EdgeMax EM180-LP is the low-profile version of Bose Professional's wide-coverage EdgeMax ceiling speaker, built around a 5.25-inch woofer and a 1.3-inch compression driver in a two-way passive design. Its PhaseGuide technology throws a 180-degree horizontal pattern from an edge or corner mounting position, which is what makes it a fit for hallways and room perimeters where a center-ceiling speaker would waste half its pattern into a wall.

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