JL Audio M6-770X 2-Way coaxial speakers (196 mm).

JL Audio M6 7.7-inch Marine Coaxial Speakers with Transflective™ LED Lighting for Infinite-Baffle Use (100 W, 4 Ω) - Gloss White Trim Ring, Gloss White Classic Grille. 
Purpose-engineered and built for real marine duty, M6 coaxial systems deliver maximum audio performance in any open-air boating environment, with the added visual impact of JL Audio’s Transflective™ RGB LED lighting.
The oversized 7.7-inch design of the M6-770X coaxial results in increased efficiency (more output for a given amount of power). 
Combine that advantage with long excursion and excellent power handling and you have a speaker system truly capable of playing loud and clear in a powerboat at speed. 
The woofer element is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 57 l). 
Operating this coaxial system in less space will compromise its low frequency performance.
A 1-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. 
You will appreciate the clean, articulate high-frequency response of the M6 dome tweeter, especially at higher volume levels.
A true 2-way passive crossover network is built into the terminal assembly to protect it from vibration and corrosion.
Although M6-770X Coaxial Systems can be used with as little as 40 W per channel, for best audio performance we recommend amplifiers capable of between 40-200 W of continuous power per channel. 

The patent-pending Transflective™ RGB LED technology emits a smooth lighting effect through the woofer cone, with a choice of several lighting colors. 
Add an optional RGB controller to create thousands of color variations.

Sold as a pair.
