Bose EdgeMax EM90 Ceiling Speaker

The EdgeMax EM90 Ceiling Speaker features Bose PhaseGuide technology with high-frequency compression drivers to create a new category that combines the room-filling coverage patterns with the 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.

Applications include:

• Retail stores
• Restaurants and bars
• Concourse
• Transportation facilities
• Resorts and hospitality venues
• Houses of worship
• Conferencing
