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.
Features
Dynamic Balance: 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.
Klippel Optimized Components: Using a state-of-the-art
Klippel Distortion Analyzer, Polk engineers were able to optimize the woofer's
motor structure, voice coil alignment and suspension for the best possible
performance, even at extreme listening levels.
Woofer Cones: Woven glass composite cones feature tremendous
stiffness-to-mass ratio. Lower mass means faster transients and finer detail.
Butyl Rubber Surrounds: For a smoother response and improved
durability, the woofers use butyl rubber surrounds. The airtight rubber
surrounds stand up to moisture, sunlight and extreme temperatures while allowing
long excursion linear motion and years of reliable use.
Silk/Polymer Composite Tweeters: The 1" liquid-cooled,
silk/polymer composite tweeters provide clear, detailed highs.
Neodymium Magnets: The speaker's neodymium magnets offer
exceptional strength to performance ratio and is extremely lightweight.
Large Diameter Voice Coils: Large diameter, 30mm voice coils
increase the speaker's reliability and power handling capacity.
Carbon Composite Basket: The speaker's carbon composite
basket is lightweight and will not flex during music audio peaks.
Crossover: The speaker comes supplied with two separate
2-way crossovers; one for each speaker. Each crossover input 36" lead is
terminated with tinned wire, and the two 20" output leads (one for the woofer
and one for the tweeter) are terminated with female quick-slides. The positive
woofer lead has a 0.250" female quick-slide and the negative woofer lead has a
0.187" female quick-slide. The positive tweeter lead has a 0.187" female
quick-slide and the negative tweeter lead has a 0.110" female quick-slide. These
quick-slides connect directly to the woofer and tweeter terminals on each
speaker. The separate 2-way crossover network sends the appropriate frequencies
to each driver for cleaner sound and better imaging. Dimensions: width = 3.515",
height = 1.015", depth = 2.645"
Mounting: This
speaker can be used in both 5x7 and 6x8 applications. The speaker's integrated mounting
ring allows the speaker to be mounted in a 5x7 or 6x8 cutout.
Note: This speaker does not come supplied with grilles. You will
need to use your factory grilles.
Marine Certified Woofer: Polk MM Series speakers are built
to withstand exposure to moisture and UV rays, so they work well in boats and
cars. They also include stainless mounting hardware for corrosion and rust
resistance.
