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.
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 Swivel Tweeters: The 1" liquid-cooled,
silk/polymer composite tweeters provide clear, detailed highs. The 15-degree swivel
tweeter housings deliver direct, detailed imaging; instantly adjustable through the
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 with two separate 2-way
crossovers; one for each speaker. Each crossover's input and output wires are
attached. The 38" input 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 2-way
crossover networks send the appropriate frequencies to each driver for cleaner
sound and better imaging.
- Width: 3.5" (3.875" including wire)
- Height: 1.02"
- Depth: 2.645"
Mounting: The speaker itself has 4 mounting holes for a standard
6-3/4" application. The supplied mounting rings have multiple mounting holes for
non-standard 6-3/4" and many 6-1/2" applications, allowing the speaker to
fit more vehicles.
Grilles: Strong ABS plastic grilles are included. These computer
optimized grilles feature a spoke-wheel design.
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.
