Features
Marine Certified Woofer: This Polk MM Series woofer is built
to withstand exposure to moisture, salt water, high humidity, UV rays, and a wide
temperature range so they work well in a marine environment, such as a boat. They
also include stainless mounting hardware for corrosion and rust resistance.
Klippel Optimized: 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.
Polymer Woofer Cone with Butyl Rubber Surrounds: The Polymer
Woofer Cones and Butyl Rubber Surrounds will not break down over time and will
survive the rigors of harsh marine environments.
Copper Voice Coil and Polyamide Former: The High Temperature
51mm Copper Voice Coil and Polyamide Former withstand the most rigorous use while
maintaining extremely low distortion for bass punch and output.
Carbon Composite Basket: The woofer's carbon composite basket
is lightweight and will not flex during music audio peaks.
Input Terminals: Stainless Steel plated heavy duty spring-post
input terminals will not corrode or tarnish and accommodate speaker wire up to 10
gauge.
Preconditioning Period: Mobile Monitor subwoofers will achieve
even greater performance once they are thoroughly broken in. To break in your new
MM subwoofer, play 20 to 30 hours of music at moderate levels.
