Twelve-speaker in-ceiling set

The Acoustic Audio CS-IC83-6PR provides twelve 8-inch three-way speakers for whole-house or multi-room audio. Each unit combines a poly-cone woofer, poly-mica midrange and 13 mm soft-dome tweeter behind a paintable grille. The passive design draws power from any home receiver or amplifier with raw speaker-wire outputs.

350-watt-per-channel power handling

Every speaker is rated for 20 to 350 watts of recommended power, so the amplifier must supply at least 10 watts and no more than 350 watts per channel. Frequency response spans 40 Hz to 20 kHz at 95 dB sensitivity and 8 ohms, matching typical home-theatre receivers without extra matching networks.

Installers needing flush-mount coverage

The Pressure Lock mounting system clamps each 10.83-inch frame into a 9.45-inch cut-out with a 3.78-inch depth, requiring no separate hardware. Buyers who want powered speakers, wireless streaming or a smaller cut-out diameter should look at other designs.

Questions about this item

What does the 95 dB sensitivity mean when the speakers are driven by a typical receiver?

At 8 ohms the speakers produce 95 dB output with one watt input, so a modest 20-watt channel already reaches comfortable listening levels without strain.

How does the 8-ohm nominal impedance affect amplifier matching?

The 8-ohm load is easy for virtually any home-theatre receiver or stereo amp rated from 10 to 350 watts per channel, so no special high-current amp is required.

What ceiling cut-out and depth are needed for the Pressure Lock mounting system?

Cut a 9.45-inch round hole and allow at least 3.78 inches of clearance above the ceiling; the spring-loaded clamps then secure the 10.83-inch flange without extra hardware.
