Seven-Speaker In-Ceiling Set

This seven-piece in-ceiling speaker set from Acoustic Audio by Goldwood is built for whole-home audio or a multi-channel home-theatre installation. The frameless, paintable grilles disappear into the ceiling for a clean aesthetic. Each unit uses a traditional passive design that draws power from an external receiver or amplifier. The three-way driver array targets full-range sound coverage across multiple rooms.

Check Receiver Power and Cut-Out Size

Verify that your receiver or amplifier supplies between 10 and 250 watts per channel into raw speaker-wire outputs. The ceiling cut-out must measure 8.27 inches in diameter and allow at least 2.99 inches of mounting depth behind the drywall. CL3-rated in-wall speaker wire is required for code-compliant connections. Ensure the amplifier can drive an eight-ohm load at the stated sensitivity.

Pressure Lock Mounting and Frameless Grilles

The Pressure Lock Mounting System clamps each speaker to the drywall without separate hardware, speeding up installation. Magnetically attached edge-to-edge grilles sit flush for a frameless look and can be painted to match the ceiling. Spring-loaded raw-wire terminals accept bare conductor for quick, tool-free wiring. The three-way passive crossover network is pre-installed inside each enclosure.

Questions about this item

What comes in the CSic64 box and what extra items are needed to install and run the speakers?

The set includes seven frameless in-ceiling speakers with magnetically attached paintable grilles and spring-loaded wire terminals. You must supply a home audio receiver or amplifier with raw speaker-wire outputs rated 10 to 250 watts per channel and CL3-rated in-wall speaker wire.

The listing shows a 7-speaker set — is that the only configuration available for the CSic64?

Yes, the CSic64 is offered as a seven-speaker set with 6.5-inch poly-cone woofers, Mylar midranges and 0.5-inch Mylar tweeters in a 3-way design. No other quantity or driver options are listed for this model.

What does the 92 dB at 8 ohms sensitivity rating mean when the speakers are driven by a typical home receiver?

At 8 ohms impedance, the speakers produce 92 dB output with one watt of input, so a receiver delivering anywhere from 10 to 250 watts per channel will drive them to loud, clean levels across the 45 Hz to 20 kHz frequency range.
