Bose EdgeMax EM90 premium loudspeakers feature proprietary Bose PhaseGuide technology with high-frequency compression drivers to create a new category that combines the room-filling coverage patterns typical of larger surface-mount speakers with the architect-preferred aesthetics of in-ceiling models. Designed to mount near wall-ceiling boundaries, EdgeMax loudspeakers provide improved audio quality and coverage, while reducing the number of required units, compared to conventional dome-tweeter ceiling speakers.
PhaseGuide technology – provides unique asymmetrical vertical pattern for room-filling coverage when mounting near wall-ceiling boundary
Provides improved room visual appearance – for demanding interior designs by eliminating center-of-ceiling or wall-mounted loudspeakers
Nominal 90° horizontal coverage – designed for in-ceiling mounting near room corners
High-frequency compression driver – for best-in-class audio quality with superior frequency response and coverage consistency versus typical dome tweeters
8-inch woofer – with wall-boundary loading provides extended bass impact
2-way passive crossover with 70/100V transformer
New auto-hold, spring-loaded mounting arms – for fast, easy installs
Magnetically attached grill – for quick access to wiring and tap settings
UL1480A listing – for air-handling (plenum) space installation
