Hertz HMX 8 / CHMX 8 Hi-Performance Marine Coaxial Speakers
The HMX 8 hi-performance marine coaxial speakers, also available in the black option HMX 8-C, is optimized to perform in infinite baffle, with a solid bass and an outstanding output. The tweeter feature an acoustic lens optimized for best off-axis dispersion and maximized SPL.
Highlights
- Engineered and tested for the real environment of application (UV, salt-fog, vibrations, water spray, thermal shock, dust).
- 1.4” Neodymium magnet tweeter featuring a PEI material dome combined with faceplate and acoustic lens optimized for best off-axis dispersion and highest SPL.
- Sound-transparent stainless steel tweeter mesh grille providing efficient high-frequency transfer, attractive look and a rock-solid protection.
- Long-throw 32 mm (1.26”) voice coil woofer fine-tuned for infinite baffle application featuring polypropylene cone injected with UV inhibitors and co-molded Santoprene surround.

Overview
The HMX 8 hi-performance marine coaxial speakers, also available in the black option HMX 8-C, is optimized to perform in infinite baffle, with a solid bass and an outstanding output. The tweeter feature an acoustic lens optimized for best off-axis dispersion and maximized SPL. The attractive stainless steel tweeter mesh grille provides perfect high-frequency transfer and a rock-solid protection. The UV resistant polypropylene cone co-molded with Santoprene rubber surround together with the basket and grille injected with a Hi-temperature and UV resistant polymer neutralize water, dust and mud. The aramid fiber spider with silicone-insulated lead wires ensures durability and constant performance over time. The high-excursion mobile equipment is driven by a massive magnetic group, to deliver high undistorted sound pressure.
