Kappa quality with cool lighting
Kappa quality with cool lighting
These high-performance Infinity Kappa 6-1/2" marine speakers will bring outstanding sound and great-looking light to any vessel. Designed for life on the water, these rugged speakers can handle up to 100 watts RMS, and they're definitely designed to be heard when you're out on the water.
Big, bright sound
Boats can be loud, but Infinity marine speakers are made to cut through the wind and roar. Infinity's unique Plus One™ cones provide maximum speaker-cone area, so you'll enjoy high sensitivity, impressive low-frequency output, and outstanding sound. Weather-resistant, grille-mounted Mylar tweeters deliver smooth, distinctive highs.
Pick a color
When you buy Infinity Kappa speakers, great sound is a given. But these speakers also give you attractive RGB LED lighting that'll add style to your boat. Seven cool colors are available out of the box, but with an external lighting controller (sold separately), you can create unique colors that suit your boat and your style.
Ready for the outdoors
Compared to car speakers, marine speakers live a pretty harsh life with sun, spray, salt, and extreme temperatures, plus the occasional fish that gets loose on the deck. These Infinity speakers are ready for all of it, with one-piece polymer baskets, marine-ready componentry, and sealed, UV-resistant grilles that will stand up to spray and punishing sunlight for years to come.
These marine speakers are available in Titanium or White.

Features
Tweeters: The tweeters are bridge mounted to the grilles, rather than to a pole piece, thus there is no chance of water leaking through the woofer cone. The tweeter is angled slightly (fixed at approximately 30°) so the sound image can be adjusted by turning the speaker before it's mounted.
LED Illumination: Integrated into each grille, around the perimeter and on the back of the tweeter casing is a red/green/blue LED assembly, to create a glow on the woofer cone. A 12 volt power supply is needed to turn the LEDs on; depending on what combination of LED wires is connected, they light red, green, blue, yellow, purple, aquamarine, or white. A 4-wire pigtail (14" long) is provided for supplying power to the built-in LEDs.
