Polk Audio continues its tradition of making brilliant-sounding speakers in stylishly designed packages — their Mobile Monitor (MM) Series Ultra Marine speakers look great and sound even better while meeting the challenges of sun and water to bring you superior sound on your boat.

The Polk MM651UM 6-3/4" marine speakers feature honeycomb-textured woven glass fiber composite woofer cones that resist and suppress unwanted resonances yet respond very quickly for a crisp and powerful sound. Large voice coils — over an inch in diameter — give the speaker high-power handling capability and extended reliability.

These sealed speakers resist damage from UV rays and salt water, so they'll provide great sound on your vessel for years to come. Each speaker utilizes an extra-small neodymium magnet that saves space and weight, 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 1" soft dome tweeters add a sweet high end that blends perfectly with the low notes so your music stays in harmonic balance, from the electric bass all the way on up to the cymbals. Stainless steel terminal posts will not corrode or rust, keeping your speaker wires reliably connected.

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.
