AC Summed Mono Speaker Operation

This AC series speaker is designed for use in areas where even distribution of sound is desired but stereo imaging is not practical because of space limitations, such as a bathroom or long hallway.

With a dual voice coil woofer and dual tweeters, this AC series speaker can sum stereo amplifier channels into a mono audio signal. Two pairs of input terminals allow connection of both channels from a stereo amplifier to a single summed mono speaker. Set the switch on the back of the speaker to 16Ω for summed mono operation.

Caution! Amplifier damage will occur if the AC6-8CD is set to 8Ω with two amplifier channels connected!

AC6-8CD Conventional Speaker Operation

This speaker can be used to reproduce a single channel of audio by making connection to either set of input terminals and setting the switch on the back of the speaker to 8Ω. In this configuration, both woofer voice coils and both tweeters are driven in parallel by the connected amplifier channel.

Placement

Plan your speaker placement carefully. Make certain that electrical, plumbing and any other services will not interfere within the ceiling where you plan to install your speakers. The AC6-8CD speaker can be mounted in walls, but are typically used in ceilings. The speaker should be located so that it provides even coverage at your listening position.

New Construction

If you are installing your speakers in new construction before the finished walls go up, AudioSource offers New Construction Brackets, which provide a stable frame that can be fastened to the wall studs or ceiling joists on 16” or 24” centers. This allows the sheet rock or other surface covering to be installed and provides a template to cut the opening for the AC6CD or AC8CD speaker.

Existing Construction

In most modern buildings ceiling joists are positioned on 16” centers, providing a space between the joists of approximately 14 3/8”. The specifications chart shows the appropriate cut out sizes (p. 4). Additionally, you should allow an extra 3/4” in all directions behind the ceiling surface to allow room for the screw clamps that mount the speaker to the ceiling to swing into position.

Use a stud finder to locate the joists behind the ceiling surface. Also, you should now check for obstructions like cross bracing in front of and behind the desired speaker location.
