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.

Angled Woofer: The LC80FX is equipped with an 8" Aerated Polypropylene woofer, loaded into the frame at a fixed 15° angle. This allows you to direct the woofer toward the listening area when used for front stage (Left, Center, or Right) speakers. When used as rear surrounds or as 6.1 or 7.1 channel surround back speakers, you can direct the driver toward the listening area for a more direct sound field, or toward a wall for a more diffuse sound field.

Dual Tweeters: Each speaker has dual 3/4" Ring Radiator tweeters 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 tweeters are angled 90° away from each other.

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

Imaging Switch: The LC80FX offers switchable "Solid" and "Diffuse" imaging patterns to create the surround effect you desire. A "Diffuse" image is defined as one which creates a "cloud" of sound, as ambient sounds fill the environment around the listening area. A "Solid" image is one which creates a more directional, localized, pin-point sound.

Wall Distance Switch: It is recommended that the speaker be placed more than 2' from a side wall. If position limitations demand than they be installed less than 2' from a side wall, the proximity of the surface can result in a response "bump" between 50Hz and 200Hz, causing the speaker to sound "boomy." The Wall Distance switch flattens response and tunes out the "boominess" without sacrificing deep bass response.

Mounting Options

Installation: The speaker requires a cutout diameter of 9-3/8" with a depth of 4-5/8" assuming 1/2" drywall. Once the hole is cut, the speaker can be held in place 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.
