Hertz HMX 8-TW

The HMX 8-TW is a high-performance 8" (20cm) marine coaxial speaker provided by the renowned supplier Hertz. Known for its superior durability and consistent performance, it is driven by a massive magnet to deliver high, undistorted sound pressure. The tweeter of this model is specially optimized for off-axis operation, which maximizes the sound pressure level. The UV-resistant polypropylene membrane, combined with a high-temperature and UV-resistant polymer, guarantees additional protection against water, dust and mud. Together with HMX 8-TW you get a device that optimally combines quality and durability.
