How is the build quality of the HMX 6.5 S-LD-G ensured?

The HMX 6.5 S-LD-G is designed for harsh marine conditions. The housing is made of ASA plastic, which is resistant to UV radiation and saltwater. The woofer uses polypropylene with UV inhibitors to ensure long life and consistent performance. The speaker membranes are designed to be resistant even in inclement weather. The sport grille is paintable and integrates perfectly into the design of sporty boats, so no visual compromises need to be made.

What are the dimensions of the HMX 6.5 S-LD-G and is installation easy?

The HMX 6.5 S-LD-G from Hertz has a diameter of 6.5 inches and a mounting depth of 95.6 mm, making it compact and easy to install. When installing, you need to ensure there is enough space to accommodate the mounting dimensions of 128 mm and the required cutout of 125 mm. Its design makes it particularly suitable for sport boats, where space is often limited. The straightforward installation is facilitated by the clean design without excessive components.

How does the HMX 6.5 S-LD-G perform in extreme weather conditions?

Specifically designed for use in marine environments, the HMX 6.5 S-LD-G from Hertz offers exceptional weather resistance. The use of ASA plastic and polypropylene ensures that the speaker remains stable even under intense sunlight, high humidity, and salty air. The polypropylene membranes are equipped with UV inhibitors to prevent degradation from sunlight. The product is designed to function reliably over a long period, even in adverse weather conditions, while providing consistent sound quality.

Is the HMX 6.5 S-LD-G compatible with my boat?

The compact size of the HMX 6.5 S-LD-G from Hertz makes it compatible with a variety of boat types, especially sporty models. With a mounting diameter of 165 mm, this speaker can fit into many standardized mounting openings. If adjustments are needed for specific boat models, the paintable sport grille helps to integrate the speaker harmoniously into the boat's aesthetics. The speaker depth of 172.2 mm fits well in most positions on the boat, making installation easier.

What are the technical specifications of the woofer in the HMX 6.5 S-LD-G?

The woofer of the HMX 6.5 S-LD-G from Hertz is equipped with a voice coil measuring 25 mm in diameter, making it particularly robust. The magnet of the woofer is made of high-density flux ferrite and measures 78.5 x 32 x 17 mm. This configuration ensures that the speaker reproduces low frequencies accurately without distortion. This makes it ideal for use at sea, where clear bass reproduction is required in loud ambient noise. The electromechanical sustainability is underscored by the Xmech of ±6.65 mm.

What features does the tweeter in the HMX 6.5 S-LD-G have?

The tweeter of the HMX 6.5 S-LD-G is equipped with a 20 mm voice coil and uses a neodymium magnet that is lightweight while providing high magnetic strength. This quality allows for crystal-clear reproduction of high frequencies. Due to the magnet configuration, the dynamic range of the frequency response is extended up to 25 kHz, making even fine details clearly audible. The compact size of the tweeter magnet, measuring 19.7 x 3 mm, allows for a streamlined speaker structure while still covering high-frequency ranges.

What advantages does the RGB accessory offer for the HMX 6.5 S-LD-G?
