Hertz HEX 6.5 M-O 6.5" Marine Coaxial Speakers - Pair

The Hertz HEX 6.5 M-O marine coaxial speakers combine detailed sound reproduction, compact sizing, and durable construction designed for life on the water. With 50W RMS power handling, a high-efficiency tweeter, and a shallow mounting profile, they deliver clear audio for marine installations where space is limited. Available in black (HEX6.5MCO) and white (HEX6.5MWO), these speakers offer a clean, refined appearance that complements a variety of boat interiors and deck layouts.

Hertz Pure Marine Certified, the HEX 6.5 M-O speakers are built to withstand demanding marine conditions. They feature IP65 water protection, UV resistance tested to ASTM-D4329 standards, and salt-fog resistance tested according to ASTM-B117 standards.

The 6.5-inch coaxial design delivers balanced audio with 50W RMS and 100W peak power handling. A frequency response of 50 Hz23 kHz helps reproduce a broad range of audio, while the shallow mounting profile makes these speakers suitable for installations with limited space behind the mounting surface.

The high-efficiency tweeter is developed using FEM simulation technology to improve off-axis sound dispersion. A 13 mm PEI dome tweeter and neodymium magnet help reproduce high-frequency detail, while the woofer's high-density ferrite magnet supports controlled midbass performance.

The polypropylene woofer cone incorporates UV inhibitors to help resist prolonged sun exposure. Silicone-insulated lead wires and nickel-plated corrosion-resistant terminals support dependable operation in marine environments. A sealed built-in crossover with a resettable solid-state tweeter protection circuit adds another layer of protection during use.

The sound-transparent mesh grille provides a clean finish while allowing sound to pass through. Its twist-and-lock system helps keep the grille securely in place.
