The Bose Professional EM90 is a premium EdgeMax in-ceiling loudspeaker that combines room-filling coverage with discreet architectural integration. Using advanced phase-guide technology and a high-output compression driver, the EM90 delivers 90° of asymmetrical coverage, allowing fewer loudspeakers to cover more space. With its 8-inch woofer, integrated 70/100V transformer, and clean ceiling-flush design, it’s ideal for commercial spaces such as conference rooms, retail environments, houses of worship, and hospitality venues.
