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.
Each speaker features
a 6-1/2" Dynamic Balance, aerated polypropylene woofer for deep,
accurate bass. For a smoother response and improved durability, each woofer uses
a rubber surround.
Tweeters: Each 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
Terminals: Each speaker features
gold-plated spring post terminals.
Accessible Controls: The LC60i
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 each 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. Each 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
Infinite Baffle Tuning:
Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior
moisture-resistant materials allow you to install each speaker in a bathroom,
kitchen, sauna, even under outdoor eaves.
Timbre-matched: The speakers
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.
Paintable: The grilles and
flanges can be painted, allowing the speakers to match any décor.
Clear plastic paint masks are included to protect the "unpaintable" speaker
Installation: Each speaker
requires an 8-1/16" diameter cutout with a depth of 5-1/16" behind
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 speakers in
drywall, make sure the wall or ceiling material can safely support the weight of
each speaker before installation; each speaker weighs approximately 5 pounds.
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.
