HMX 6.5-TW is a 6.5 inch (16.5 cm) coaxial speaker from Hertz with 75 W RMS, 150 W Peak, 4 Ohm, and 89 dB SPL. The frequency response ranges from 50 to 25,000 Hz, the diameter is 165 mm, and the depth is 95.6 mm. A neodymium tweeter with a 36 mm PEI dome, front plate, and acoustic lens is designed for off-axis radiation, complemented by a sound-transparent stainless steel grille. The woofer uses a 25 mm voice coil, a polypropylene diaphragm with UV inhibitors, and a molded Santoprene surround, driven by a solid magnetic group with high-density flux ferrite. An aramid fiber spider with silicone-insulated connection wires, an injection-molded marine-grade polymer basket, a sealed built-in crossover with a resettable solid-state tweeter protection circuit, and gold-plated, corrosion-resistant terminals are integrated. Tested for UV, salt mist, vibrations, splash water, temperature shock, and dust. Xmech is ±6.65 mm, and the magnet sizes are 78.5 x 32 x 17 mm (woofer) and 19.7 x 3 mm (tweeter).

What is the power handling of the HMX 6.5-TW from Hertz?

The Hertz HMX 6.5-TW is designed for various applications and offers a power handling of up to 75 watts RMS. At peak, it can handle up to 150 watts, allowing it to reproduce intense volumes without distortion. These power handling values are optimal for use in marine environments, where irregular audio passages can occur. The stable performance of the speaker is supported by its robust construction and high-quality materials, such as the polypropylene diaphragm and aramid centering, which can withstand consistently high levels.

How does the HMX 6.5-TW protect against environmental influences?

The Hertz HMX 6.5-TW marine coaxial speaker is optimally protected against environmental influences. The speaker features a waterproof polypropylene diaphragm equipped with a UV inhibitor to prevent sun damage. A Santoprene surround provides additional protection against water and dust. The stainless steel grille not only secures the base components against physical damage but also protects against corrosive elements. These features make the HMX 6.5-TW resistant to salt mist and other environmental stresses, ideal for use in marine and open environments with consistently stable performance.

How do the TSP of the HMX 6.5-TW affect the sound?

The Thiele-Small parameters (TSP) of the Hertz HMX 6.5-TW, such as Qts 0.7, Fs 65 Hz, and Vas 8.8, significantly shape the sound characteristics. A Qts value of 0.7 indicates a balanced bass response that is neither too boomy nor too flat, ideal for portable sound converters. The resonance frequency value Fs of 65 Hz means that the speaker can accurately handle low tones, while the Vas of 8.8 indicates the air displacement capabilities in the enclosure. Combined, these parameters create a stable and rich acoustic experience with controlled bass reproduction and clear highs, optimized for use in infinite baffle applications.
