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.
Marine Certified: Polk/MOMO Series speakers are built to withstand exposure to moisture and UV rays, so they
work well in boats and cars.
Lacquered Carbon-fiber Woofers:
The lacquered carbon-fiber cones provide the ideal balance of stiffness and low
mass for the clearest, most detailed midrange performance, and lowest
distortion, of any speaker in its class.
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.
1" Silk/Polymer Composite
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 grille.
Cast Aluminum Baskets: Each
speaker has a channel-vented, acoustically inert cast aluminum basket for
superior stiffness and better heat dissipation.
1" Kapton Voice Coils and
Formers: Laser-based, Klippel-optimized, channel-vented 2-Layer 1"
Kapton voice coils and formers offer high heat dissipation and extreme power
handling.
NOMEX Spiders: The strong,
fire-retardant flat NOMEX spiders allow extended linear motion while providing
highly reliable mechanical and thermal stability.
Dual Nickel-plated Terminals:
Each speaker has dual nickel-plated terminals for component-like connections.
ABS Magnet Boots: Each speaker
features a waterproof, anti-resonant ABS magnet boot, which is removable for
installation flexibility. With the magnet boots installed, each speaker has the
following dimensions:
- Magnet Diameter: 3.033"
- Depth as top: 2.624"
- Depth as bottom: 2.765"
Crossovers: The
2-way crossovers have big components for better dynamic impact and
transparency. Each crossover has the following dimensions: L=4.698",
W=2.426", H=1.033".
Crossover Connections: Each
crossover input lead is terminated with tinned wire, and the two 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.

Note
ABS Magnet Boots: Each speaker
comes with an ABS magnet boot installed, however, the Crutchfield database measurements
were taken with the magnet boots removed. With the magnet boots installed, each
speaker has the following dimensions:
- Magnet Diameter: 3.033"
- Depth as top: 2.624"
- Depth as bottom: 2.765"
