Polk Audio continues its tradition of making brilliant-sounding speakers in stylishly designed packages — their Mobile Monitor (MM) Series speakers look great and sound even better. Each speaker utilizes an extra-strong, extra-small neodymium magnet that saves space and weight, allowing these speakers to fit into more places in more vehicles while still delivering a full sound with lots of kick. Their lightweight carbon composite frames provide strong, flex-free support for the speakers' motor assemblies.

The Polk MM6501 6-3/4" component system features 6-3/4" woofers with honeycomb-textured woven glass fiber composite cones that respond very quickly for a clean, crisp, and powerful sound. Large voice coils — over an inch in diameter — give the speaker high power handling capability and extended reliability.

Separate 1" silk dome tweeters add a sweet high end that blends perfectly with the low notes, and swivel mounts let you aim the tweeters to produce a superior sound stage in your car. The external crossovers direct the signal flow so all your music stays in perfect harmonic balance, from the electric bass all the way up to the cymbals. A tweeter attenuation setting allows you to tweak the high-frequency level to your taste.

Important Note: These Polk speakers use a low-impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with virtually all factory and aftermarket stereos.

Note: Polk describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.
