Six-Speaker In-Ceiling System

The Acoustic Audio CS-IC83 pack supplies three stereo pairs of 8-inch flush-mount speakers for whole-home audio or home-theatre surround installations. Each unit uses a traditional passive design that draws power directly from any compatible receiver or amplifier with raw speaker wire outputs.

Sustained Output and Dispersion

Wide-dispersion drivers maintain consistent coverage during extended listening sessions, while the 3-way passive crossover separates low, mid and high frequencies for stable fidelity at moderate to high volumes. The 95dB sensitivity at 8 ohms ensures efficient power transfer from amplifiers rated between 10 and 350 watts per channel.

Upgrade Path and Fit

This set replaces older 2-way in-ceiling models or bookshelf speakers when a builder wants flush aesthetics and broader dispersion without additional floor hardware. The Pressure Lock mounting system clamps to drywall without separate brackets, fitting a 9.45-inch cutout and 3.78-inch mounting depth. Buyers who need weather-rated enclosures or powered wireless modules should look elsewhere.

Questions about this item

How much heat or noise does the CS-IC83 generate when it runs all day?

The CS-IC83 is a passive in-ceiling speaker with no internal amplifier or fan, so it produces no audible noise and negligible heat during continuous use.

What must I already own to drive the CS-IC83?

You need a home audio receiver or amplifier that provides raw speaker-wire outputs and can deliver between 10 and 350 watts per channel into an 8-ohm load.

Will the CS-IC83 work with my older receiver that only has spring-clip terminals?

Yes, the CS-IC83 uses spring-loaded raw-wire connections that accept bare wire from any standard receiver or amplifier, regardless of age.
