Speaker Features

High-performance speakers with LED light

Hertz designed their HMX 6.5 S-LD 6-1/2” marine speakers to bring high-quality audio and high style to your boat. These rugged speakers will handle up to 75 watts RMS, so they’ll be able to cut through the noise from your engine and the wind. With big magnets, polypropylene cones, and acoustic lens tweeters optimized for off-axis dispersion, you’ll love the sounds you hear. The cool, built-in RGB LED lights look great, too.

Built-in LED light

These Hertz speakers bring something extra to the party – multi-color LED lighting. The RGB LED lighting circuit sits just below the tweeter and it’s protected by a transparent cover that also acts as a light diffuser. In order to control the multi-color RBG, you’ll need an RGB controller (sold separately).

Ready for action

The speaker basket and grille are made from a rugged, UV-resistant polymer that stands up to water, dust, and mud, while the stainless steel mesh grille protects the tweeter from both dirt and damage. Aramid fiber spiders, silicone-insulated leads, and Santoprene rubber surrounds also help keep these durable speakers rockin’ for years to come.
