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.
Frequency Response Note
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.
Polymer Composite Woofers: The
speaker features two lightweight, yet stiff mineral-filled polymer composite woofers with
good damping, giving you high efficiency, excellent bass, and low distortion.
For high performance durability, each woofer uses a butyl rubber surround and an
acoustically inert stamped driver basket.
Silk/Polymer Tweeter: The
speaker has a 0.75" fabric/polymer dome tweeter with a neodymium magnet that provides clear, detailed
Mylar Capacitors: The speaker
utilizes Mylar bypass capacitors to extend its high frequency response and
improve detail and transparency.
Acoustically Inert Cabinet: The
speaker cabinet features all-MDF construction with internal bracings that
virtually eliminate sound-muddying resonance.
Port: There is a single
critically-tuned port opening on the rear of the speaker that has low port noise
for increased and extended bass response.
Grille: The speaker features a
removable anti-diffraction cloth grille that minimizes grille diffraction for
spacious, three-dimensional imaging.
5-Way Binding Posts: The
5-way binding posts will accept bare wire, pin connectors, spade
connectors, banana plugs, and dual banana plugs.
The speaker is magnetically shielded, allowing you
to place it on your television without distorting the picture.
Timbre-Matched: The Polk CSR is
designed to be used as a center-channel in any Polk Audio home theater or
multi-channel music system for a more realistic seamless surround sound
Mounting: The center-speaker
comes with 4 rubber self-adhesive feet to help secure the speaker in place to
prevent slippage and vibration. The center-speaker does not come with any type
of wall-bracket or key-hole slot for wall-mounting the speakers.
Frequency Response Note
Frequency Response: The overall frequency response is 40Hz-24kHz, and the -3dB frequency response is
