In-Ceiling Audiophile Beast
The beefy big 8-inch woofer of the RC80i makes a big beastly impact,
with the maximum amount of bass you're likely to encounter from an
in-ceiling speaker. The RC80i is perfect for areas requiring big, rich
sound with good coverage, but with no room for traditional speaker
clutter. Designed for superior wide dispersion, you'll hear great sound
no matter where you are in the room.
A unique dual tweeter housing delivers both left & right channel
highs, while a vented dual voice coil driver automatically "sums" left
& right channel mids for true stereo imaging.
Easy one-cut, drop-in installation puts built-in audio within
reach, with Perfect Fit templates, a precision flange, and (available)
pre-construction brackets.
RCi speakers utilize the "virtual enclosure" of your in-wall
and in-ceiling space to enhance their bass response and smooth low
frequency blending with the midrange.
Lightweight and stiff blue polymer cones deliver excellent damping and bass response.
Durable, computer-modeled, injection-molded butyl rubber
surrounds suppress unwanted cone resonances for a lifetime of reliable
sound.
Rustproof stainless steel hardware, durable butyl rubber
surrounds and powder coated aluminum (in-ceiling) & painted steel
(in-wall) grilles make RCi Series speakers suitable for high moisture
areas like bathrooms or even under eaves of an enclosed porch. (RCi
series are not suitable for exposed outdoor use).
RCi speakers have paintable grilles and practically disappear into any room.
RCi Series speakers are timbre-matched to other Polk speakers
to insure utterly seamless blending from speaker to speaker in systems
that combine traditional and built-in speakers.
