More about the product
The Hertz HMX 6.5C is a premium marine coaxial speaker designed to deliver powerful and clear sound in harsh outdoor environments. Built for boats and marine applications, this model combines durability with high-quality audio performance. Its design features a robust structure that resists water, salt, and UV rays, ensuring long-lasting reliability even under extreme conditions.
The speaker uses a 6.5-inch polypropylene cone that provides excellent rigidity and responsiveness. This material helps produce deep, punchy bass while maintaining clarity in the midrange. Paired with a 1.4-inch tweeter dome, the HMX 6.5 delivers crisp and detailed high frequencies, creating a balanced sound profile suitable for open-air listening.
The Hertz HMX 6.5C is engineered with a corrosion-resistant basket and grille, making it ideal for marine environments. The grille design not only protects the internal components but also adds a stylish touch to any installation. The speaker is IP65 rated, meaning it is fully protected against water jets and dust ingress. This level of protection ensures dependable performance in wet conditions, whether exposed to rain or sea spray.
Installation is straightforward thanks to its standard mounting dimensions and integrated design. The speaker is compatible with most marine audio systems and can handle up to 75 watts RMS power, delivering strong output without distortion. Its frequency response ranges from 50 Hz to 25 kHz, covering a wide spectrum for rich and dynamic sound.
While the Hertz HMX 6.5C excels in durability and audio quality, it is a coaxial speaker, so it may not provide the same level of separation and detail as a full component system. However, for marine use where space and simplicity matter, this model offers an excellent balance of performance and resilience.
