Hertz HMX 7.7 S-LD-G 7.7" 100W RMS Marine RGB LED Coaxial Speakers - 4 Ohm (Gray)

The Hertz HMX 7.7 S-LD-G represents a significant step up in marine audio, offering a larger 7.7-inch surface area that provides a noticeable boost in bass response and overall output compared to standard 6.5-inch speakers. Engineered specifically for the harsh realities of marine and powersports environments, these speakers deliver a "Hertz Sound Experience" that remains crystal clear even at high speeds and against the backdrop of engine and wind noise.

Superior Acoustic Engineering

At the heart of the HMX 7.7 is a long-throw 7.7-inch woofer with a 1.26-inch voice coil, tuned to provide high-impact mid-bass that you can feel. This is paired with a 1.4-inch neodymium magnet tweeter featuring a PEI dome and an acoustic lens specifically designed to optimize off-axis dispersion. This ensures that the high frequencies reach your ears clearly, regardless of where the speakers are mounted in the cockpit or cabin.

Integrated RGB LED Lighting

The "LD" designation indicates integrated RGB LED lighting, which is built into the tweeter bridge beneath the high-transparency polycarbonate grille. This lighting circuit is designed for durability and provides a sophisticated glow that can be customized to match your vessel's mood or existing lighting setup. The gray "S-style" sport grilles offer a modern, aggressive look that blends seamlessly with contemporary marine interiors.

Built for the Elements

The HMX 7.7 S-LD-G is built to exceed industry standards for durability. It features an IP65 rating, ensuring complete protection against water jets and dust. The components are crafted with UV-inhibitors to prevent the gray finish and cone materials from fading or becoming brittle under constant sun exposure. Furthermore, the speakers are tested for salt-mist and fog resistance, ensuring that the internal components and connectors remain free from corrosion over years of service.

Key Features:

Enhanced Bass: 7.7-inch diameter provides a larger cone area for deeper, more powerful low-end response.

High Power Handling: Rated at 100W RMS (200W Peak) to cut through ambient noise.

Integrated RGB LEDs: Customizable lighting adds a premium visual element to your audio setup.

Weatherproof Design: IP65 certified and ASTM-D4329/B117 tested for UV and salt spray resistance.

Optimized Tweeter: 1.4-inch PEI dome tweeter with an acoustic lens for superior high-frequency detail.

Rugged Construction: High-impact gray sport grilles protect the internal components from physical damage.
