Bose Professional’s EdgeMax series combines the performance of big, bulky surface-mount loudspeakers with stealthy design to shatter the limitations of traditional in-ceiling loudspeakers.
Dual drivers and patented PhaseGuide® technology allow EdgeMax loudspeakers to project powerful, focused sound from the room’s edges to the center. They deliver amazing directionality and voice intelligibility to ensure all listeners enjoy the same sound—regardless of their location.
Larger rooms with higher SPL needs, such as fitness centers, benefit from the powerful, deeper 9-inch (24 cm) cans of EdgeMax EM. In these demanding environments, EM models deliver proven performance, with immersive full-frequency sound for music and clear intelligibility for voice, even at high volumes. Also, EM models are designed with 75-degree vertical coverage, optimal for rooms with higher ceilings.
