Polk's LCi-C anchors dialogue to your screen with crystal-clear accuracy. This in-wall center channel speaker takes advantage of the same sophisticated technologies that have made Polk's critically acclaimed LSi loudspeakers so successful. And since it installs directly into your wall, you get clean, high-impact sound without any room clutter whatsoever.

High-performance design
This speaker owes its impressive performance to a sturdy build and careful design. Polk's high-quality construction keeps the speaker's drivers in rigid alignment, and virtually eliminates sound-muddying resonance. An advanced tweeter delivers smooth, extended highs with impressive detail. It's swivel-mounted, so you can direct the sound toward your favorite listening position. And Polk engineered the woofers to provide clear, precise midrange and bass, as well as even sound coverage throughout the room.

An optional in-wall bracket is recommended for installing the LCi-C in-wall center channel speaker in a home with new construction.

Create a hidden home theater with the LCi-C and other LC in-wall speakers, plus a CSW in-wall or in-floor subwoofer. You can also can also combine the LCi-C with LSi free-standing speakers.

Features

Dynamic Balance Technology: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Dual Midranges: The speaker has dual 5-1/4" Dynamic Balance, aerated polypropylene midrange drivers for clean, distortion-free midrange. The midrange drivers use rubber surrounds.

Cascade Tapered Array: The midranges are aligned in a Cascade Tapered Array, in which one driver plays only bass frequencies, and the other bass and midrange, for broad, even sound coverage for off-axis listeners.

Tweeter: The speaker uses a 1" Ring Radiator tweeter for crisp, transparent highs. The ultra-light woven Ring Radiator Diaphragm delivers flat response, precise detail and overall accuracy. A High Frequency Waveguide prevents phase cancellations for smooth, uniform frequency response and wide dispersion. A Low Frequency Waveguide promotes laminar airflow between chambers to prevent air turbulence. This feature serves the same function as Power Port for Polk's bass systems. The ball-and-socket swivel mount lets you aim the tweeter in any direction to give you direct high-frequency control, resulting in excellent imaging even for off-axis listening positions.

Infinite Baffle Tuning: Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior bass response.

Timbre-matched: The speaker is timbre-matched to the Polk Audio LCi Series for seamless, enveloping imaging when used in a home theater system. You can mix and match any of the LCi-series in-wall and in-ceiling speakers with the LCi Series high performance floor-standing and bookshelf speakers.

Terminals: The speaker features gold-plated spring post terminals.

Wiring Recommendations: The gauge of the speaker wire used to connect this speaker depends upon the length of the run:

  • Lengths of up to 25': 18 or 16 gauge
  • Lengths between 25' to 50': 16 or 14 gauge
  • Lengths between 50' and 75': 14 or 12 gauge
  • Lengths of over 75': 12 gauge

Controls

Tweeter Attenuator: If the listening room is very reflective, with smooth sheetrock walls, hardwood floors, and non-cushioned furniture, the sound will overly "bright" and unnatural. In this case, you can engage the LCi -3 dB Tweeter Attenuator (select the "Cut" setting) to flatten the room response without hindering higher frequency response for warmer, more realistic sound and more accurate imaging. The Tweeter Attenuator control is located on the speaker's front panel.

Mounting Options

Installation: The speaker requires a cutout 13-1/8" wide and 7-5/8" high with a depth of 3-1/2" assuming 1/2" drywall. Once the hole is cut, the speaker can be dropped in and the Rotating Cams can be tightened, allowing you to secure the speaker to the drywall without any extra assembly. If you will not be mounting the speaker in drywall, make sure the wall or ceiling material can safely support the weight of the speaker before installation; the speaker weighs approximately 8-1/2 pounds.

Paintable: The grille and flange can be painted, allowing the speaker to match any décor. A clear plastic paint mask is included to protect the "unpaintable" speaker parts.

An outstanding center channel speaker

Written By John, Westminster, MD on Thursday, March 19, 2009

Crutchfield Customer Review (What's this?)

Superb fidelity and unobtrusive footprint. I'm really happy with this one.

The BEST center channel speaker I've ever heard

Written By Michael, Orange County, CA on Monday, June 09, 2008

Although pricey, this is a speaker that is well worth the money, it will tie
together all your dialogue on a surround sound system. Don't cut corners
on your speakers, spend the money up front and they will reward you for
years to come.
