Audiophile Home Theater from Speakers You Can Barely See

The LCi-C was specifically designed for use as a center channel loudspeaker in a built-in home theater system. It uses the same ring radiator tweeter and aerated polypropylene driver technologies as LSi and LCi Series speakers for seamless integration and surround imaging. Mix and match the LCi-C with in-wall and/or in-ceiling models from the LCi Series for a system that will stun your with its power and accuracy. Add a built-in subwoofer or two from our innovative CSW Series and completely eliminate the clutter of free-standing home theater speakers.

Polk continues its tradition of creating audiophile sound for home theater systems from speakers you can barely see. As with all the loudspeakers in the LCi Series, the LCi-C center channel is built to the same performance standards as the finest free-standing home theater speakers while remaining unobtrusive and easy to install.

LCi-C Features:

Fits easily built-in between 16-inch on-center studs.

Dual driver Cascade Tapered Array design for broad sound coverage even for off-axis listeners.

The naturally open area of the acoustically transparent grille never gets in the way, for superior on- and off-axis response.

Paintable grilles let you build them in, and then forget all about them; LCi Series practically disappear into any room.

Enhanced, reengineered ring radiator tweeters extend top-end response for incredible details, with a 15° swivel housing for direct high frequency control and excellent imaging even in off-axis listening positions.

Our aerated polypropylene cone is the ideal balance of lightweight stiffness (for more efficient action with less distortion-causing flex) and superior damping properties, for spectacular midrange clarity and punchy bass.

Polk Audio’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

Lightweight, rigid driver baskets constructed of specially engineered composite materials keep moving parts in rigid alignment and damp performance-robbing resonances for better performance in shallow space installs.

Easily accessible custom audio controls allow you to tweak your sound for optimum performance in any installation: Use the reflective room (tweeter) compensation switch to digitally compensate for harsh reflective surfaces, and the wall distance setting toggle to compensate for proximity to corners or adjacent walls.

PowerPort® bass venting is Polk Audio’s patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more efficient, deep bass impact.

Rustproof stainless steel hardware and powder coated aluminum grilles make LCi Series speakers suitable for high moisture areas like bathrooms, transitional spaces or even under eaves or in the ceiling of an enclosed porch. (LCi Series are not suitable for exposed outdoor use. For outdoor speaker fun, use our Atrium® Series.)

LCi Series speakers are timbre-matched to Polk Audio LSi speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.

LCi Series speakers are packaged one-per-box, so you can use singles as front or rear center channels, or as additional-zone speakers anywhere.

Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) pre-construction brackets; achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system.

All Polk Audio products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk Audio loudspeakers are built to perform for a lifetime.
