The AC75 features a tuned port Bass Reflex enclosure that has an improved low frequency response over a conventional enclosure. The integrated 70V/100V line matching transformer allows for parallel connection of multiple AC75 loudspeakers in distributed installations. The installer and system designer have a choice of 4 sensitivity settings (7.5W, 15W, 25W, and 8 ohm bypass) selected via a rotary switch located on the rear jack panel of the enclosure. These sensitivity or “tap” settings can also be used as a relative volume adjustment within the distributed system.

Included with the AC75 is a heavy gauge zinc plated and paint matched U-bracket for permanent installation. Threaded fasteners are available on the rear of the enclosure and can be used with optional ball-mount hardware.

One channel of discrete amplification and signal processing is required for this product. The preferred signal processors for the AC75 is the McCauley M Series family of loudspeaker controllers.
