Frameless 6.5" In-Ceiling 3 Speaker Set

The Acoustic Audio CSic64 set includes three frameless in-ceiling speakers designed for home theater and distributed audio. Each unit uses a 3-way driver array with a 6.5" poly cone woofer, Mylar midrange, and 0.5" Mylar tweeter. The magnetic grilles attach edge-to-edge for a clean, paintable finish that blends into the ceiling.

Ideal for whole-home audio.

These speakers suit owners who want discreet, flush-mounted sound throughout living areas or a dedicated home cinema. The passive design requires a separate receiver or amplifier with raw speaker wire outputs. Buyers seeking powered speakers, wireless connectivity, or extreme high-output performance should consider alternative designs.

45Hz–20 kHz frequency response at 92dB sensitivity

The system delivers a frequency range of 45Hz to 20 kHz with a sensitivity rating of 92dB at 8 ohms. Amplifier power between 10 and 250 watts per channel is supported. Installation uses a Pressure Lock Mounting System fitting an 8.27" cutout with 2.99" mounting depth and 8.86" overall diameter.
