Features

Overview: The Bose EdgeMax EM180 is a full-range, in-ceiling premium loudspeaker featuring proprietary Bose PhaseGuide technology and comprised of an 8" woofer and a high-frequency compression driver that provide room-filling coverage patterns typical of larger surface-mount speakers 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. Typical applications for the EM180 are restaurants and bars, airport concourses, transportation facilities, conferencing, and hospitality venues.

Mounting: The EM180 features auto-hold, spring-loaded arms, designed to make installation much easier. The spring-loaded arms allow the speaker to be slid into the mount opening, but prevents it from sliding back out. Four tightening-screws on the front face of the speaker tighten the spring-loaded arms against the back of the ceiling. When the screws are backed off all the way, the arms are compressed in allowing the speaker to slide back out of the opening. The EM180 is directional  and when mounted along a wall or in a corner, the speaker gives 180˚ of horizontal and 75˚ of asymmetrical vertical coverage. The speaker also features a magnetically attached grill for quick access to the wiring and tap settings and has a UL1480A listing for air-handling (plenum) space installation.

70/100 Volt: Designed to work in both 70 and 100 volt installations, the EM180 can handle 125 watts RMS/500 watts peak, and also has an 8Ω bypass to run the speaker from a standard amplifier. All wiring connections are done via a 6-pin Euroblock (Phoenix) connector that has terminals for 70/100 V and 8Ω inputs and includes pass-thru connections for daisy-chaining speakers together. The wiring connector and tap selection dial are both accessed on the front of the speaker, making them easy to change by simply pulling off the magnetic grill.
