2-Way Full Range, 1" x 5.25"
125W  /  85Hz - 18kHz  /  90° x 90°
The AC75 is a passive 2 way loudspeaker designed for permanent installations. This low profile, high output, weather resistant speaker features a treated direct radiating 5.25” cone loudspeaker and a 1” direct radiating high frequency driver. The AC75 delivers reference monitor sound quality at high foreground levels and is designed for both horizontal and vertical installation. It is housed in a durable UV-resistant, paintable, all weather enclosure that is available in both black or white. The AC75 features an internal multi-tap transformer which allows 70V and 100V operation are direct 8 ohm bypass.

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. The System Design Group can help in creating a complete amplification and signal processing solution.

"The installation of the speakers went in so well. We could not have done this job within budget if McCauley had not been able to customize the loudspeakers for application. We were able to get them all up easily and efficiently."
