If you're serious about sound, but don't want bulky speaker cabinets cluttering your décor, check out the LC80i in-ceiling speaker from Polk, sold individually. It takes advantage of the same sophisticated technologies that have made Polk's critically acclaimed LSi loudspeakers so successful. And since this speaker installs directly into your ceiling, you get clean, high-impact sound without taking up an inch of floor space.

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 woofer to provide clear, precise midrange and bass.

Designed for performance and durability
Careful design and sturdy build are a must for high-performance in-ceiling sound. Polk's high-quality construction keeps the speaker's drivers in rigid alignment, and virtually eliminates annoying resonance. The LC80i is rust- and moisture-resistant for safe use in bathrooms, kitchens, saunas, and even under outdoor eaves. (For new-construction installation, we recommend Polk's Performance Enclosure, sold separately, for the best possible in-ceiling sound.)

Stereo and home theater options
Use a pair of the LC80is for accurate stereo sound. They also make a great choice as surround speakers for your home theater. Put together an "invisible" system using the LCi in-ceiling and in-wall speakers with a powered sub. Since the LCis are voice-matched to Polk's LSi loudspeakers, you can mix and match in-ceiling, in-wall, and free-standing speakers to suit your listening space.

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.

Woofer: The speaker features an 8" Dynamic Balance, aerated polypropylene woofer for deep, accurate bass. For a smoother response and improved durability, the woofer uses a rubber surround.

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.

Moisture-resistant: Durable, moisture-resistant materials allow you to install the speaker in a bathroom, kitchen, sauna, even under outdoor eaves.

Timbre-matched: The speaker is timbre-matched to the Polk Audio LSi 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 LSi Series high performance floor-standing and bookshelf speakers.

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

Controls

Accessible Controls: The LC80i features technology that can tailor the sound for performance in difficult or unusual placement situations. The following controls are located on the front panel of the speaker (behind the grille):

  • Wall Distance Toggle: In-wall speakers excel when placed more than 2' from side walls. When the speaker is mounted closer than 2', the result is a "bump" in response between 50 and 200 Hz. The speaker has a Distance Toggle Switch circuit that flattens the response and tunes out the "boominess" if mounted closer than 2' from a side wall.
  • 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.
  • Area Targeting: Engaging this function expands the area of high frequency response, improving off-axis imaging.

Mounting Options

Installation: The speaker requires an 9-7/16" diameter cutout with a mounting depth of 5-1/4" (includes 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 4 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.

Performance Enclosure Compatibility: An optional Polk Audio custom built LCi Performance Enclosure gives the LCi in-wall/in-ceiling speaker the performance edge by hiding a complete, perfect-volume speaker cabinet within the wall before the wall is even completed. The LCi Performance Enclosure is specially constructed of high density MDF and fill material in a size that fits securely between wall and ceiling studs in pre-drywall construction. Adjustable brackets make pre-construction installation simple. Vibration-damping foam pads ensure rattle-free performance.
