Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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.
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
Infinite Baffle Tuning:
Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior
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.
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
- Area Targeting: Engaging
this function expands the area of high frequency response, improving
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.
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
