Frameless In-Ceiling Speaker Pair

The Acoustic Audio CSic84 is a two-piece set of frameless in-ceiling speakers designed for home audio and home theater systems. Each unit uses a three-way driver array with an 8-inch poly cone woofer, a Mylar midrange and a half-inch Mylar tweeter. The magnetic edge-to-edge grilles create a flush, frameless look that blends into the ceiling.

Whole-Home Audio Installations

These speakers suit installers and owners who want wide sound dispersion from a low-profile ceiling mount without visible hardware. The Pressure Lock system clamps directly to drywall, so no separate brackets or screws are required. Buyers who need weather-resistant models for outdoor eaves or who require an active design with built-in amplification should consider other options.

40Hz-20kHz Frequency Response

The system covers 40Hz to 20kHz at 95dB sensitivity and an 8-ohm load, so a receiver or amplifier delivering between 10 and 350 watts per channel will drive them cleanly. Spring-loaded raw-wire terminals accept CL3-rated speaker cable for in-wall runs. The cutout diameter is 10.16 inches and the mounting depth is 4.06 inches.

Questions about this item

How much heat or noise do the CSic84 speakers add when running all day?

The passive CSic84 speakers generate no heat or fan noise themselves; only the connected amplifier produces warmth and audible noise during extended use.

What must I already own to drive the CSic84 pair?

You need a home audio receiver or amplifier with raw speaker wire outputs capable of 10 to 350 watts per channel at 8 ohms, plus CL3-rated speaker wire for the in-ceiling run.

Will the CSic84 integrate cleanly with my older receiver that only has spring-clip terminals?

Yes — the speakers use spring-loaded raw wire connections that accept bare wire from any amplifier with speaker-level outputs, including legacy spring-clip models.
