Big sound where you want it These rugged 11" wakeboard tower speakers are massive in size, but they're very easy on the ears. With a durable poly cone and Tractrix high-frequency horn that houses a 1" titanium-dome compression driver, they'll cut through wind, waves, and engine roar to deliver big-time sound without harshness. Kicker recommends powering these speakers with 300 watts of power, so make sure your marine amps are up to the challenge. The 359-degree swiveling clamp system is easy to install and lets you rotate the speakers (without tools!) to suit your situation. Point them aft for water skiing or wakeboarding, or spin them inwards to enjoy your music when you're anchored out. Whatever you're doing, these Kickers will make your day on the water just a little bit better than it was already. Get the lighting look you want Seven-color LED grilles are included, but you can access twenty color options and 19 dynamic modes using the optional Kicker KMLC remote. The KMLC gives you multi-function control of the LED lighting by managing color and dynamic mode functions, including adjustable brightness, fade, speed/strobe, and auto save. Either way, these speakers will give you years of audio and visual enjoyment. Built to last Designed for life on the water, these 4-ohm speakers feature sealed motors, rubber cone surrounds, and locking terminal covers to keep spray away from the internal componentry. They'll also stand up to harsh sunlight, thanks to special UV treatments on the cones, surrounds, baskets, and grilles that meet or exceed ASTM standards. The durable stainless steel/ABS clamps will fit tubing from 1-1/2" to 3-1/8", so these speakers will work on a wide variety of vessels.
