Frequently Asked Questions about HEX 6.5 S-LD-G


What size is the Hertz HEX 6.5 S-LD-G speaker?

The Hertz HEX 6.5 S-LD-G is a 6.5-inch marine coaxial speaker with an exact physical size of 165 mm. The installation dimensions are also important to note: with a cutout diameter of 172 mm, it fits many standard openings in boats. The depth of 85 mm ensures that the speaker easily fits into most installation spaces without requiring additional room. Notably, the sound transparency is enhanced by the sport grill, which not only provides protection but is also aesthetically pleasing and proportionate to the size.

What are the performance specifications of the Hertz HEX 6.5 S-LD-G?

The Hertz HEX 6.5 S-LD-G speaker offers a continuous power handling of 50 watts RMS and a peak power handling of 100 watts. This ensures excellent volume and clarity even during prolonged use. The nominal impedance is 4 ohms, meaning it is compatible with most standard amplifiers without any issues. With a frequency response of 50 Hz to 23 kHz, this speaker delivers a balanced and clear sound that is ideal for audio playback on the high seas. The efficiency is complemented by a sound level of 88 dB, contributing to a powerful audio experience.

How is the Hertz HEX 6.5 S-LD-G installed in a boat?

Installing the Hertz HEX 6.5 S-LD-G requires careful attention to the physical dimensions. You will need a cutout diameter of 172 mm and a mounting depth of 85 mm to properly integrate the speaker. Pay attention to the IP65 certification during installation, which ensures protection against water and dust, as well as the corrosion resistance of the nickel-plated terminals. This keeps the speaker securely anchored in your boat while also optimally protected against harsh marine conditions.

Is the Hertz HEX 6.5 S-LD-G equipped with LED lighting?

Yes, the Hertz HEX 6.5 S-LD-G is equipped with an innovative RGB LED lighting option. This lighting, controlled by the HM RGB 1 BK Controller, allows you to customize the colors to create the right mood on your boat. The LEDs are robust against external influences and have been optimized for maritime use. They not only enhance the aesthetics of the speaker but also provide a customizable lighting experience that is both functional and decorative, complementing your sound enjoyment at sea.

What is the technical advantage of the neodymium tweeters in the Hertz HEX 6.5 S-LD-G?

The Hertz HEX 6.5 S-LD-G is equipped with a tweeter that uses neodymium magnets to ensure improved sound performance. These magnets provide superior magnetic performance at a low weight, which is extremely beneficial for use in speakers. They contribute to high efficiency and a clear sound profile, which is particularly advantageous in non-axial installations typical of boat environments. The tweeter membrane has a diameter of 24 mm, ensuring balanced high-frequency behavior and clearly reproducing sound details.

How does the Hertz HEX 6.5 S-LD-G protect against maritime environmental influences?

The Hertz HEX 6.5 S-LD-G features several characteristics that make it ideal for use on maritime vehicles. Important is the IP65 protection class, which ensures a high level of water and dust protection. Additionally, the speaker meets ASTM-D4329 and ASTM-B117 standards, guaranteeing UV resistance and corrosion resistance in saline environments. The nickel-plated connections are protected against rust. A robust polypropylene woofer with UV inhibitors contributes to its durability, while the high-quality neodymium tweeters also minimize non-axial high-frequency distortion.

How is the RGB lighting of the Hertz HEX 6.5 S-LD-G controlled?

The RGB LED lighting of the Hertz HEX 6.5 S-LD-G is managed by the HM RGB 1 BK Controller. This controller includes a high-frequency remote control that allows you to manage various color modes and transition activities. The LEDs can be adjusted to your mood or the ambiance of your boat, providing a particularly atmospheric option for nighttime use. The lighting is integrated and thus robust against external impairments, making it ideal for use in maritime conditions.

What Thiele Small parameters does the Hertz HEX 6.5 S-LD-G have?

The Hertz HEX 6.5 S-LD-G speaker is equipped with specific Thiele-Small parameters that ensure optimal tuning and performance. The resonance frequency value (Fs) is 78 Hz, while the mechanical compliance of the suspension (Cms) is 0.31 mm/N. The electrical inductance (Le) is 0.109 mH, and the mechanical mass (Mms) is 13.5 g. The BL factor, which indicates the magnetic strength, is 4.8 T*m. These parameters significantly contribute to clear and precise sound reproduction, ideal for use in open marine environments.

What role does the crossover play in the Hertz HEX 6.5 S-LD-G?

The Hertz HEX 6.5 S-LD-G features an encapsulated crossover designed specifically to enhance protection and sound separation. It includes a resettable protection circuit for the tweeters, ensuring longevity and reliability under stress. This crossover separates the high from the low tones, resulting in clear and precise audio output. The high-quality construction and insulation of the crossover are crucial for the performance and protection of the speaker in demanding marine environments.

How is the polypropylene woofer in the Hertz HEX 6.5 S-LD-G supported?

The polypropylene woofer in the Hertz HEX 6.5 S-LD-G speaker benefits from the use of a flux ferrite magnet, which provides high density. This combination allows for remarkable sound stability and quality. Additionally, the woofer is treated with UV inhibitors to counteract the effects of sunlight, thereby increasing longevity. The speaker is designed for free-air applications and uses silicone-insulated connection wires to maximize resistance to marine environmental influences and ensure smooth, long-lasting use.
