About the Polk Ultramarine UMS66WR
Big sound and bright LED light
Big sound and bright LED light
Polk's Ultramarine speakers are designed to produce maximum sound in marine applications. The innovative design features “air suspension” technology and high-temperature voice coils, so they'll crank up to 150 watts and rock your boat for seasons to come. You can also enjoy Polk's cool-looking XKGLOW RGB light halos. You can add an XKGlow controller (sold separately) and adjust your lighting using the free app.
Designed to look and sound great
These 6.6" UMS66BR speakers have rugged, removable sport grilles that stand up to sunlight and moisture. They're available in three colors, too, so you can choose the style that's right for your boat.
Underneath, you'll find UV-treated silver polypropylene cones, durable surrounds, and cast aluminum baskets. The 1" titanium dome tweeters handle the highs, so your music will sound crisp and clear, even when you're hammering along open water at full throttle.

Marine-Tested: The speakers are subjected to ASTM B117 (Salt Fog) and ASTM D4329 (UV exposure) testing to ensure they meet marine industry standards.
LEDs: There are multi-color LEDs in the back of the tweeter casing, to create a glow on the woofer cone. To control the lighting, Polk recommends using the XKGlow Bluetooth controller (sold separately) with their XKChrome universal smartphone App (available for Apple and Android devices). If you prefer, the plug on the LED power wires can be cut off and the speakers wired to a 12 volt power supply, through a switch and fuse, or to a different brand controller. (The wires are not labeled, so this will require some testing to connect correctly.) Depending on what combination of wires is connected, the LEDs can light red, green, blue, yellow, pink, aqua, or white.
Tweeters: The titanium dome tweeters are mounted to the grilles, rather than to a pole piece, thus there is no chance of water leaking through the woofer cone.
Grille: In addition to the fixed spoke style grille on each speaker, snap on plastic trim rings and grille covers are included to install if you like.
Note: The packaging indicates the trim rings are not designed to be removable once installed.
