HERTZ AUDIO HMX 8 TC – 8″ 4 Ohm Marine Coax, Black

HMX 8 TC features a tone-on-tone stainless steel front mesh matching the grille colour. Coaxial speaker 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 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.

1. Engineered and tested for the real environment of application (UV, salt-fog, vibrations, water spray, thermal shock, dust).

2. 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.

3. Sound-transparent tone-on-tone stainless steel tweeter mesh grille providing efficient high-frequency transfer, attractive look and a rock-solid protection.

4. Long-throw 25mm (1”) voice coil woofer fine-tuned for infinite baffle application featuring polypropylene cone injected with UV inhibitors and co-molded Santoprene surround.

5. Aramid fiber spider with silicone-insulated lead wires ensuring durability and constant performance over time.

6. FEM optimized high-excursion mobile equipment driven by a massive magnetic group encapsulated into a marine-grade polymer injected basket.

7. Sealed built-in crossover with resettable solid-state tweeter protection circuit.

8. Gold-plated corrosion resistant terminals.
