JL Audio M6 8.8-inch Marine Coaxial Speakers – Gloss White Sports Grille (Pair)

The Ultimate Offshore Sound Engine. Subwoofer-Level Bass. Reference Clarity.

When standard marine audio simply isn't enough, step up to the absolute heavyweight champion of open-water sound. The JL Audio M6-880X-S-GwGw speaker system represents the largest, most powerful coaxial drivers in the flagship M6 lineup. Engineered for high-speed offshore boats, wake arches, and larger vessels, these massive 8.8-inch speakers cross traditional boundaries by delivering bass response that rivals standalone marine subwoofers—all while maintaining pristine high-frequency vocal clarity.

By jumping to the colossal 8.8-inch format, you gain more than double the cone surface area of a traditional 6.5-inch speaker. This massive physical advantage moves significantly more air, giving you enormous efficiency, longer acoustic throw, and a full, deep soundstage that effortlessly punches through excessive engine hum, high-speed wind, and heavy waves. Wrapped in the striking, multi-spoke Gloss White Sports Grille, they offer an aggressive, ultra-premium visual edge to your vessel.

Key Features

• Colossal 8.8" Performance Footprint: The ultra-oversized cone format generates massive, hard-hitting mid-bass punch and smooth low-end extension, completely redefining the audio potential of an open cockpit or wake arch.

• Oversized 1.25-inch Silk Dome Tweeters: To perfectly balance the massive woofer, the M6-880X features a specially treated, reference-quality 1.25-inch pure silk dome tweeter—the largest in the industry for a marine coaxial speaker. It serves up silky, highly detailed high frequencies that stay perfectly crisp even at competitive volumes.

• True Marine® Certified Construction: Built from the inside out to laugh off the harshest offshore conditions. Featuring advanced UV-resistant polymer baskets, synthetic fiber spiders, and completely sealed internal crossovers, the M6 line offers total protection against saltwater corrosion, moisture, and extreme sun damage.

• Infinite Baffle Mastery: Purpose-built to thrive without a dedicated enclosure. These drivers utilize the large volume of open air inside your boat's bulkheads, gunwales, or wake towers to act as a giant natural speaker box for deep, distortion-free sound signature.
