Seven-Speaker Home Theater Set

The Acoustic Audio CSic84 is a seven-piece in-ceiling system built for multi-channel home theater. It delivers a centre, front, middle, rear and surround layout from a single package. Traditional passive design means it draws power directly from any compatible receiver or amplifier. Wide dispersion drivers integrate with new or existing installations.

Frameless Flush Mount and Pressure Lock

Paintable edge-to-edge grilles attach magnetically for a frameless look that sits flush to the ceiling. The Pressure Lock Mounting System clamps to drywall without separate hardware. Each unit fits a 10.16 inch cut-out and requires 4.06 inches of mounting depth. Overall diameter measures 10.94 inches with spring-loaded raw wire terminals.

8-Inch Three-Way Driver Array

Eight-inch poly cones with progressive spiders and butyl rubber surrounds handle low frequencies. Mylar midranges and half-inch Mylar tweeters cover the upper registers. Three-way passive crossovers manage the split for greater fidelity. Frequency response spans 40Hz to 20kHz at 95dB sensitivity and eight ohms. Buyers needing powered speakers or wireless connectivity should look elsewhere.

Questions about this item

How do I install the frameless in-ceiling speakers and what step do people often miss?

Cut a 10.16" round hole, ensure at least 4.06" mounting depth, then use the Pressure Lock Mounting System to clamp the speaker to the drywall — no hardware needed. The step often missed is verifying the 4.06" clearance above the ceiling before cutting.

What maintenance or replacement will the 7-speaker set need over time?

The passive design has no internal electronics to service. Long-term care is limited to occasionally dusting the paintable magnetic grilles and checking that the spring-loaded raw wire connections remain tight on your amplifier.

What limit appears first when the 8" 3-way speakers run at high volume for long periods?

The 95dB sensitivity at 8 ohms and 40Hz-20kHz response mean thermal compression in the voice coils of the 8" poly woofers, 0.5" mylar tweeters, and mylar midranges will likely become audible before the passive crossovers reach their limits.
