Purpose-engineered and built for real marine duty, M3 coaxial systems deliver excellent performance at a more affordable price than our maximum-performance M6 models.

The M3-650X 6.5-inch coaxial speaker is designed around the standard marine 6.5-inch speaker format and features a wide mounting flange with a four hole mounting pattern.

The long excursion woofer design and excellent power handling make your music come through loud and clear at speed, or at anchor. The woofer design 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 0.75-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics.

Although M3-650X Coaxial Systems can be used with as little as 20 W per channel, for best audio performance we recommend amplifiers capable of between 75-100 W of continuous power per channel.

Marine Tested Design: 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.

Coaxial Tower Speaker: Enclosed in these injection-molded enclosures are JL Audio’s MX-Series 7.7″ coaxial tower speakers. Specifically tuned for tower enclosure applications, these coaxial drivers deliver clean, loud audio that can be heard well beyond the boat when mounted up high. Like all JL Audio marine speakers, this system is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.

• Tweeter: The 3/4″ silk dome tweeter is specially designed to withstand UV and salt-spray exposure. The dome tweeter uses a neodymium magnet for higher efficiency levels and is Ferrofluid-cooled and damped for improved response and power handling capabilities.
• Woofer: The woofer consists of an injection-molded, mica-filled polypropylene cone with UV inhibitors, synthetic rubber surrounds, and precisely engineered dust cap profiles for smooth upper-end response. The woofers also use marine-grade synthetic fiber spiders with a progressive roll design to withstand high humidity.

Polymer Enclosure: The specifically engineered, injection-molded, marine-grade polymer enclosures and grilles are corrosion and UV-resistant to protect the tower speakers from the harsh marine environment. The enclosures feature a decorative, aluminum logo cap on the end opposite the speaker, which can be oriented to match any custom mounting application.

Mounting Hardware (Sold Separately): Each enclosure is designed to mate with one of JL Audio mounting fixtures (sold separately, and available to fit a wide range of applications). These mounting fixtures are marine-grade stainless steel and will hold up to marine life. Check the accessory list for available mounting fixtures.

Note: If you need help determining the correct pipe-mounting clamp for your installation, then download JL Audio’s Pipe-Mounting Clamp Ruler.

Speaker Wiring: The speaker cables exit through the center of the mounting fixtures, staying high and dry, and out of sight. The speaker cable consists of Red, Black, Green, and White wires. The Red and Black are positive and negative speaker wires. The Green and White wires are present in case you would like to add the JL Audio LED light rings (sold separately) to the front of the speakers.

Power Recommendation: For best results, JL Audio recommend powering this system with an amplifier in the 25 to 150 watt per channel range.

Installation Note: Professional installation is strongly recommended.

Marine Tested: JL Audio’s marine speakers are built to exceed industry standards for Salt-Fog and UV exposure. They are exposed to ultraviolet testing chambers to simulate years of sun exposure, and salt fog chambers to simulate years of exposure to salt-water environments. Corrosion and UV-resistant materials are used throughout.

Woofers: The MX770-CCX-CG-WH speakers feature injection-molded, mica-filled polypropylene cone woofers with UV inhibitors, synthetic rubber surrounds, and precisely engineered dust cap profiles for smooth upper-end response. The woofers also use marine-grade synthetic fiber spiders with a progressive roll design to withstand high humidity.

DMA (Dynamic Motor Analysis): DMA is JL Audio’s proprietary method of improving dynamic motor behavior. The DMA optimized, long-excursion design enhances output, bass extension, and power handling of the speaker.

Tweeters: The speakers feature 3/4″ silk dome tweeters with a specially formulated treatment to withstand UV and salt-spray exposure. The dome tweeter uses a neodymium magnet for higher efficiency levels and is Ferrofluid-cooled and damped for improved response and power handling capabilities.

Crossover: The tweeters use 2nd order (12 dB/oct) crossovers with solid-state tweeter protection to prevent tweeter failure.

Polymer Basket And Grille: The specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer’s motor system to prevent corrosion.

Infinite-Baffle Operation: The speakers are designed for infinite-baffle operation and can be installed in a variety of locations, without the need for a dedicated enclosure. The woofer is optimized to operate with a large volume of air behind it (at least 2 cubic feet); operating in less space will compromise low frequency performance.

CCX (Cockpit Coaxial) models have woofers specifically designed for infinite-baffle applications. This means that they are designed to operate without an enclosure. More specifically, the woofer design is optimized to operate with a large volume of air behind it (at least 2 cu. ft.). The bass response of the speaker will suffer significantly if placed in a small enclosure, so make sure your system is planned accordingly. The MX-Series is purpose-engineered and built for real marine duty and has been specifically designed to deliver maximum audio performance in any open-air boating environment. Although MX770-CCX Coaxial Systems can be used with as little as 20 W per channel, for best audio performance JL Audio recommends amplifiers capable of between 75 – 100 Watts of continuous power per channel, like the JL Audio M400/4.
