The Hertz HMX 7.7 S-LD marine speakers combine clear audio performance, rugged construction, and customizable RGB LED lighting for your boat's sound system. Featuring a 7.7-inch woofer with a 25 mm (1-inch) voice coil and a 1.4-inch neodymium tweeter, these speakers are designed for open-water listening, delivering strong bass and detailed high frequencies. Built for demanding marine environments, the HMX 7.7 S-LD speakers feature Hertz Pure Marine Certified construction, IP65 protection, and resistance to UV exposure and salt fog. The paintable sport grilles allow you to customize their appearance, while integrated RGB lighting adds a vibrant touch to your onboard audio setup.
