Hertz HMX 6.5-TW

The HMX 6.5-TW represents the pinnacle of Hertz innovation. It is a 6.5" (16.5cm) diameter marine coaxial loudspeaker that stands out above all for its excellent technical properties. Its tweeter has been optimized for maximum sound pressure levels in off-axis operations and impresses with a robust and durable construction. In addition, the loudspeaker has a UV-resistant polypropylene membrane that is protected from environmental influences such as water, dust and mud by its Santoprene rubber surround, basket and grille. In addition, the stable performance of the loudspeaker is guaranteed over time by the aramid centering with silicone-insulated connecting wires. As another big plus, a massive magnet produces a high, undistorted sound pressure level.
