The marine environment presents a special challenge. Salt water, high humidity, wide temperature range and relentless pounding from the sun take a toll on speakers. Many marine speakers trade on-water durability for sound quality. Not so with the MM651UM- a dedicated Ultra Marine model for your watercraft needs. Designed and styled specifically for use in the marine environment, it isn't just car speaker labeled for use on a boat. Use it in a speaker can or installed on your boat, it works great for both! A unique tweeter-on-grille design eliminates the traditional tweeter post, resulting in a totally sealed front. With waterproof materials, it will stand up to just about any harsh marine environment while sounding great.

    I have had multiple boats and all had stereo systems. My Polk audio speakers have outlasted and out performed all of my previous speakers. They are mounted on the side of my center console and get wet at least once per week. So far, so good! Capt Wayne
