Surface-mount performance sound meets stealth-mode design.
EdgeMax loudspeakers combine bold surface-mount performance with stealthy design to shatter the limitations of traditional in-ceiling loudspeakers. Patented PhaseGuide® technology enables EdgeMax loudspeakers to project powerful, focused sound asymmetrically from the room’s edges to the center. New EdgeMax LP models feature an 80-degree vertical coverage angle for use in rooms with lower ceilings, and their shallow 4-inch backcan is ideal for spaces with above-ceiling limitations and tighter clearances. Larger rooms with higher SPL needs benefit from the powerful, deeper 9-inch cans and 75-degree vertical coverage of the original EdgeMax models. EdgeMax models are purpose-built to provide specific horizontal coverage. The EM90-LP’s 90-degree horizontal coverage angle is optimized for corner placement, with wall-boundary loading providing extended bass impact. Integrators can “mix and match” original EdgeMax and new LP loudspeakers, particularly in challenging installations with varying space dimensions and above-ceiling obstructions.
FEATURES
