M-Series 7.7-inch Marine Tower Component System for Enclosed Use (100 W, 4 Ω) - White Sport Grille
Purpose-engineered and built for real marine duty, the M-Series component systems deliver maximum audio performance in any open-air boating environment.
The oversized 7.7-inch design of the M770-TCS component woofer 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 M770-TCS component woofer is optimized to operate in a small sealed enclosure, such as a tower speaker system. If you need a system with a 7.7-inch component woofer that operates without a dedicated enclosure, select our M770-CCS, instead.
To keep up with the capabilities of the component woofer, we employ a 1-inch pure silk dome tweeter that is specially treated to withstand the marine environment. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics. You will appreciate the clean, articulate high-frequency response of the M-Series dome tweeter, especially at higher volume levels.
A true 2-way passive crossover network is sealed in a protective capsule and mounted to the woofer's frame so that it does not require additional mounting provisions.
Although M770-TCS Component Systems can be used with as little as 40 W per channel, for best audio performance we recommend amplifiers capable of between 75-150 W of continuous power per channel.
Sold as a pair.
Marine Materials / Testing
The design of marine products requires extensive materials testing to achieve reliability and longevity.
Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments. This testing is critical to building products that will not only sound great in your boat, but will also sound great for many, many years.
- injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
- Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
- Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
- Gold-plated, marine-grade brass connection terminals
- Marine-grade stainless steel mounting hardware is included.
Built in U.S.A. with Global Components
JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
At a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow. To pull this off in a competitive world market, our production engineering team has created one of the world’s most advanced loudspeaker assembly facilities and established a global network of quality component suppliers who build to our specifications. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A.
Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we find it is vital that the people who designed them have close access to the people manufacturing them. The following JL Audio products are built in our Miramar, Florida factory, with global components:
- Subwoofer Drivers: W7, W6v3, TW5v2, TW3, TW1, W3v3
- Enclosed Car Subwoofers: Stealthbox®, PowerWedge™, ProWedge™, H.O. Wedge™ & MicroSub™ Enclosed Subwoofers
- Marine Loudspeakers, Marine Subwoofer Drivers and Marine Enclosed Loudspeakers
- Home Subwoofers: Dominion™, E-Sub, Fathom® and Gotham®
