Polk Audio MM840DVC - The Subwoofer
Introducing the new MM840 high performance 8-inch subwoofer. Great for big bass without taking up much space. As a result of 3 years of Polk research and development, the new MM systems have been designed to offer unparalleled sound quality with exceptional fit to meet virtually any application. Borrowing technology from our flagship SR Series, the MM Series offers exceptional value for the price. Through the use of high-tech carbon composite baskets, powerful neodymium motor structures using oversized voice coils, and state-of-the-art woven glass composite cones, we offer high-end audio performance normally found only in the most expensive loudspeaker systems.

No one’s music is really all there without a dedicated subwoofer to add the thump that gives a performance its raw, in-your-face feeling. If you’re serious about your music, you want to take a serious look at our subwoofers for filling out the low notes. And Polk subwoofers are styled to make an install a real contender on the show circuit. All at a price that’s hard to beat.
