MM Series Superior Performance

The Mobile Monitor Series by Polk Audio is the result of 3 years of research and development. The series uses high quality materials and the newest loudspeaker technology to bring the listener an unforgettable experience. The best part about the MM Series is the affordable price.



What does Marine Certified mean?

The MM Series speakers get put through the ASTM (American Society for Testing and Materials) marine testing to become marine certified. The speakers go through two harsh tests: the B117-03 Standard Practice for Operating Salt Spray (Fog) Apparatus and the D4329-99 Standard Practice for Fluorescent UV Exposure of Plastics. The Salt Fog tests exposes the components 95° Fahrenheit and 5% salt solution for 500 hours and the UV test puts the speakers through 8 hours of UV-B light, black body temperature of 60 degrees Celsius and 4 hours condensate water, black body temperature of 40 degrees Celsius. These tests ensure these speakers will last in the harshest of marine environments.

Unbelievably clear, and can take a beating like Tina Turner

I upgraded my pontoon boat from two very underpowered and very unclear speakers to 8 of the Polk 6.5". I've been on the lake now five or six times and I've had more people ask what audio system I'm running in that boat. Polk has been very consistent in their products that I have purchased. I'm very happy and would definitely buy more if my boat had more room! The speakers are unbelievably clear and sharp. they do not have a tiney sound and I cannot seem to max out the power to distort them. I wish I had these in my vehicles too!!
