with high frequency compression drivers

Bose Professional EdgeMax™ in-ceiling premium loudspeakers feature proprietary Bose PhaseGuide® technology and high-frequency compression drivers that combine room filling sound with the style of in-ceiling models. Speakers mount near wall-ceiling boundaries to provide improved audio quality and coverage with fewer units.


  • PhaseGuide technology provides unique asymmetrical vertical pattern for room-filling coverage when mounting near wall-ceiling boundary
  • Provides improved visual appearance in rooms by eliminating center-of-ceiling or wall-mounted loudspeakers
  • Nominal 180° horizontal coverage for in-ceiling mounting near room corners
  • High-frequency compression driver for best-in-class audio quality with superior frequency response and consistent coverage
  • 8-inch woofer with wall-boundary loading provides extended bass impact
  • 2-way passive crossover with 70/100V transformer
  • Auto-hold, spring-loaded mounting arms for easy installs
  • Magnetically attached grill for quick access to wiring and tap settings
  • UL1480A listing for air-handling (plenum) space installation
