Frequently Asked Questions about HMX 6.5-TC

What are the key technical features of the HMX 6.5-TC from Hertz?

The HMX 6.5-TC from Hertz is a marine coaxial speaker with a diameter of 6.5". The peak power is 150 watts, and the nominal power is 75 watts at an impedance of 4 ohms. The woofer cone is made of UV-resistant polypropylene, while the tweeter dome is made of PEI. The robust magnet allows for a significant sound pressure level, while the neodymium magnets in the tweeter ensure precise high-frequency reproduction. Additional technical details include a woofer voice coil with a diameter of 25 mm and a tweeter voice coil of 20 mm.

How does the HMX 6.5-TC perform in terms of frequency response?

The HMX 6.5-TC offers a frequency response of 50 Hz to 25 kHz, covering a wide sound range from deep bass to high frequencies. This range is achieved through the combination of a large yet lightweight polypropylene cone and an optimized 36 mm neodymium magnet tweeter. The electromechanics with a Bl value of 5.2 T*m and an effective diaphragm size of 125 mm contribute to clear and distortion-free reproduction. Additionally, the Santoprene surround ensures high excursion stability, ideal for infinite baffle applications.

What makes the tweeter of the HMX 6.5-TC special?

The tweeter of the HMX 6.5-TC features a 1.4-inch neodymium magnet and a PEI dome. This combination provides clear and precise high-frequency reproduction. The design is optimized for off-axis radiation, allowing perfect sound to be perceived even from a side listening position. The front plate and acoustic lens support efficient sound distribution. Additionally, a stainless steel grille protects the delicate parts without compromising sound transparency. The compact 20 mm voice coil contributes to accurate sound reproduction.

What materials and protection features does the HMX 6.5-TC offer?

The HMX 6.5-TC is designed for the harsh conditions of the marine environment. The polypropylene membrane is UV-resistant and withstands salt mist and temperature fluctuations. Santoprene rubber surrounds provide flexibility and durability. Encapsulated in a marine-grade polymer basket, the construction is stable. Additionally, the speaker features a resettable solid-state tweeter protection circuit in the crossover that catches unwanted overloads. Gold-plated, corrosion-resistant terminals ensure long-term use, even in humid environments.

What are the dimensions of the HMX 6.5-TC and how can it be installed?

The HMX 6.5-TC from Hertz has a diameter of 172.2 mm and a mounting depth of 95.6 mm. The installation requires an opening size of 128 mm. The woofer magnet size is 78.5 x 32 x 17 mm, while the tweeter magnet has a diameter of 19.7 mm. A precise fit for the intended installation locations is possible due to the well-thought-out dimensions. Especially if you want to install it in vehicles or on boats, pay attention to the mounting depth and any necessary clearance behind the speaker. This allows for seamless integration.

What advantages does the massive magnet in the HMX 6.5-TC offer?

The massive magnet in the HMX 6.5-TC plays a central role in the speaker's performance. It is made of high-density ferrite and guarantees uninterrupted and undistorted sound output. This structure allows for a high sound pressure level and ensures powerful bass reproduction, ideal for energetic music. The magnet also supports the voice coils of the woofer, which have a long stroke of ±6.65 mm. These features enable a dynamic sound image. The combination of these advantages makes the reproduction of energetic music pieces particularly impressive.

How does the aramid fiber spider affect the performance of the HMX 6.5-TC?

The aramid fiber spider in the HMX 6.5-TC from Hertz provides stability and precision at high excursions. Its design ensures improved control of the diaphragm movements, which guarantees uniform sound output. The silicone-insulated connection wires further contribute to reliability and prevent overheating or wear issues. These construction features ensure that even with intensive use, a consistent and distortion-free sound is maintained. Even in challenging environments, such as at sea, the acoustic performance remains unaffected.

How does the Santoprene surround affect the sound characteristics?

The Santoprene surround of the HMX 6.5-TC speaker enables pronounced durability and flexibility in diaphragm movement. This surround supports the UV-resistant polypropylene diaphragm and ensures that the woofers remain stable even at high volumes. This flexibility not only provides rich, deep bass but also precise reproduction at lower frequencies. This surround offers greater excursion space, supported by the speaker's high-performance magnetic systems, promising clear sound reproduction even at high levels.

What role does the Crossover play in the HMX 6.5-TC from Hertz?

The Crossover of the HMX 6.5-TC efficiently divides the frequency range between the tweeter and woofer for optimal sound output. The protection circuit for the tweeter prevents sound distortions and overloads by intervening when necessary. This integrated Crossover features strict crossover frequencies that ensure the tonal balance between the components. This guarantees that both high and low tones are reproduced clearly and precisely, allowing the speaker to deliver optimal overall performance.

What advantages does the Hertz HMX 6.5-TC offer for marine applications?

The Hertz HMX 6.5-TC is ideal for marine applications as it is designed for conditions such as UV radiation, salt mist, vibrations, splashes, and temperature shocks. The robust construction with UV-resistant materials protects against environmental influences, while the corrosion-resistant gold-plated terminals ensure long-lasting performance. The stable Santoprene surround and FEM-optimized moving components provide consistent sound quality even in fluctuating weather conditions. The speaker is particularly suitable for boats and other marine environments, where it delivers reliable performance.
