Perk up your maritime music

JL Audio's M100-CT-CG-WH marine tweeters will open up the sound of your boat's system, broadcasting all the little details that make your music sparkle.

These silk dome tweeters radiate the high frequencies in a broad pattern for excellent sound coverage, and they're treated to withstand exposure to sun and moisture. Corrosion- and UV-resistant polymer housings ensure that they'll last for many seasons on the water. JL Audio includes all the hardware you'll need for flush-mounting these durable tweeters.

The UV-resistant polymer basket encases and protects the entire structure, and as an added bonus the UV protection ensures the grilles will stay white, looking factory-fresh even after years of sun exposure.

If you're looking for a sleek, stylish way to mount your tweeters, check out JL Audio's MTPOD-M100-CL billet aluminum tweeter pods.

JL Audio M100-CT-CG-WH

Crutchfield Customer Review (What's this?)

Awesome little speakers... add a lot of sound and filled in holes in the music I didn't realize I was missing. Put them in my center console boat along with two 7.7 JL speakers and man it sounds great. 7.7's are mounted in the side facing out and mounted these in the console facing you making it much easier to hear the music when running down the lake. the ability to flush mount them was also nice...



Tweeter add-on

Crutchfield Customer Review (What's this?)

I bought these for my 2009 Yamaha 232 Limited boat. The factory Kicker speakers are located inches off of the floor facing each other. They do a fine job with the factory Sony head unit as long as the boat isn't moving. With wind noise and the engines running at 9K RPM the music would disappear. These add-on tweeters put sound up closer to ear level. Now running down the lake at 30MPH we can still hear the tunes. They were easy to install and wired directly into the factory speakers wiring.

Pros: They look and sound great. They can be installed flush or surface mount. I used a hole saw and flush mounted mine. There is plenty of wire to reach the factory speakers.

Cons: You get what you pay for. JL Audio is top notch but it will cost you. The price is more than I wanted to spend but I know that I bought high-end audio gear that does exactly what I needed it to do.
