Klipsch CS-18C 8" In-Ceiling Each

Klipsch CS-18C In-Ceiling Speaker

8" In-Ceiling Speaker with Polymer Woofer, Polymer Tweeter and Fast Sky Hook Installation

The Klipsch CS-18C is an 8-inch in-ceiling speaker designed to bring proper full-range sound to custom installation systems without blowing out the budget. Klipsch says it borrows design thinking from its premium architectural and box speaker ranges, using an 8-inch polymer woofer, a 1-inch polymer dome tweeter and the Sky Hook Cinch by Swarm installation system to speed up install time.

This is the kind of speaker that makes sense in distributed audio, media rooms and general in-ceiling music systems where you want reliable performance, decent sensitivity and a clean flush finish.

8" Woofer for Better Scale

More body than smaller in-ceiling speakers

The CS-18C uses an 8-inch polymer woofer, which gives it a useful advantage over smaller ceiling speakers when it comes to bass weight and room-filling ability. Klipsch rates the speaker from 63Hz to 20kHz ±3dB, which gives it enough bandwidth for everyday music and TV audio duties in the right room.

• Multi-room music systems
• Living room ceiling audio
• Media rooms
• Background music in larger spaces

1" Polymer Dome Tweeter

Clear top end for everyday listening

Klipsch fits the CS-18C with a 1-inch polymer dome tweeter, giving it a simple and sensible high-frequency section for general-purpose ceiling audio. Combined with the larger woofer, it is aimed at delivering a balanced full-range sound rather than acting as a token “fill speaker.”

92dB Sensitivity

Easy to drive in installed systems

The CS-18C is rated at 92dB sensitivity at 2.83V / 1m, which is a healthy figure for an architectural speaker in this class. That makes it easier to match with a wide range of amplifiers and distributed audio systems without needing huge power to get useful output.

• 40W RMS
• 160W peak
• 8 ohm compatible

Sky Hook Cinch by Swarm Installation System

Faster install, less ceiling hassle

One of the key selling points here is Klipsch’s Sky Hook patented Cinch by Swarm installation system. Klipsch says it reduces install time by 75%, which is a useful practical advantage for both installers and customers.

That matters because ceiling speaker performance is important, but so is how quickly and neatly they go into the ceiling in the first place.

Paintable Magnetic Grille

Clean architectural finish

The CS-18C uses a white paintable flat magnetic grille, which helps it blend into the ceiling once installed. Klipsch also lists a black baffle/frame behind the grille for the speaker body itself.
