Speaker Features

High-performance sound

Hertz designed their HMX 6.5 6-1/2” marine speakers to bring high-quality audio to any 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. They’re made for max volume, with big magnets, polypropylene cones, and acoustic lens tweeters that are optimized for off-axis dispersion.

Built to last

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 will help keep these durable speakers performing at a high level for years to come.
