Goldwood Sound, Inc. Acoustic Audio CSic84 8" In-Ceiling Speaker 4-Pack

Frameless In-Ceiling 4-Pack

The Acoustic Audio CSic84 set contains four frameless in-ceiling speakers designed for whole-home audio or surround sound. 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 clean, paintable finish that sits flush with the ceiling.

Installs in Drywall Without Extra Hardware

The Pressure Lock mounting system clamps directly to drywall using a 10.16-inch cut-out and a 4.06-inch mounting depth, so no separate brackets or screws are required. Spring-loaded terminals accept raw speaker wire for quick connection to any home audio receiver or amplifier delivering between 10 and 350 watts per channel. Buyers without a separate amplifier or those needing wireless or Bluetooth streaming should consider other options.

Frequency Response 40 Hz to 20 kHz at 95 dB

This sensitivity and bandwidth figure determines whether the speakers will reach reference volume in your room with the amplifier you own. The three-way passive crossovers divide the signal between the woofer, midrange and tweeter for full-range coverage. If your system demands higher output or deeper bass extension, a different speaker design will be necessary.
