The HMX 8-TW from Hertz is an 8-inch marine coaxial speaker that impresses with durable materials and a robust construction. Particularly noteworthy is the UV-resistant polypropylene membrane, which excellently repels water and dirt. The tweeter is optimized for off-axis operation, allowing for high, clear sound pressure. With a power handling of 100 W RMS and a peak value of 200 W, the speaker offers outstanding performance. The massive magnet of the woofer and the neodymium magnets of the tweeter complement each other ideally for maximum acoustic efficiency.
The HMX 8-TW from Hertz features a tweeter specifically optimized for off-axis operation. This means that the speaker delivers a clear and balanced sound even when it is not directly aimed at the listener. This characteristic enhances sound distribution, especially in open or asymmetrical environments like on boats. The integrated neodymium magnet and the PEI material dome further contribute to efficient high-frequency transmission, significantly improving the musical experience.
The Hertz HMX 8-TW covers a wide frequency spectrum from 45 Hz to 25 kHz. This means that the speaker can reproduce deep bass as well as high frequencies clearly and accurately, ensuring a balanced sound image. The long-stroke woofer with an Xmech of ±8.5 mm, together with the finely tuned 25 mm voice coil, provides impressive low-frequency performance. Such a frequency range is ideal for those who want to experience a full sound spectrum on their boat.
The robustness of the HMX 8-TW from Hertz is ensured by the careful selection of materials. The membrane is made of UV-resistant polypropylene, which not only has excellent acoustic properties but also protects against external influences such as UV radiation, water, and dust. A massive flux ferrite magnet in the woofer and a neodymium magnet in the tweeter further enhance performance and longevity. Additionally, an aramid fiber spider and silicone-insulated connection wires make the speaker particularly resilient and long-lasting in performance.
The Hertz HMX 8-TW has a diameter of 8 inches (200 mm) and a mounting depth of 123 mm. These dimensions allow for flexible installation in most common boat installation locations. The diaphragm has a diameter of 225 mm, while the dimensions of the woofer's magnet are 90 x 40 x 20 mm. Delivered with a thoughtful mounting system, the speaker can be seamlessly integrated, with the gold-plated corrosion-resistant terminals ensuring a secure connection. The measurements are crucial to ensure that the speaker fits into existing cutouts.
The HMX 8-TW from Hertz uses a particularly effective magnetic structure for its woofer and tweeter. The woofer is equipped with a flux ferrite magnet that has a high density, resulting in powerful and precise bass reproduction. The tweeter utilizes a neodymium magnet that is compact and lightweight but offers remarkable magnetic properties to efficiently transmit high frequencies. This combination ensures a balanced sound and optimal performance, even under the demanding conditions of marine use.
The thoughtful construction of the HMX 8-TW by Hertz promotes its exceptional durability. The speaker is embedded in a board made of polymer marine material, which provides additional structural integrity. The injected polymer structure and the UV-resistant membrane make it particularly resistant to environmental influences. Furthermore, the silicone-insulated wiring with water-repellent properties offers additional protection, while the FEM-optimized moving components allow for high displacement and ensure acoustic performance.
The HMX 8-TW from Hertz is equipped with a tweeter featuring a 1.4-inch neodymium magnet and PEI dome. This combination has been designed to deliver the best sound pressure level even off-axis. The acoustic lens significantly optimizes high-frequency distribution, while the stainless steel grille not only provides protection but also ensures a sound-transparent performance. The built-in crossover with a resettable solid-state protection circuit is designed to prevent any overloads, thus ensuring the best acoustic performance and reliability.
The HMX 8-TW from Hertz is equipped with a 32 mm voice coil for the woofer and a 20 mm voice coil for the tweeter. These coils are crucial for sound dynamics and control. The 32 mm voice coil of the woofer allows for high load capacity and displacement, while the 20 mm voice coil of the tweeter ensures precise high-frequency reproduction. The coil materials are designed for high temperatures to minimize heat generation and reliably maintain performance even during prolonged operation.
The crossover in the HMX 8-TW from Hertz plays a critical role in sound optimization. It is sealed and integrates a resettable solid-state tweeter protection circuit. This ensures that the transition between the tweeter and woofer occurs seamlessly, allowing for clear sound separation. The tweeter's protection mechanism minimizes the risk of overloads by effectively distributing the signals according to their frequency to the respective driver systems. This ensures a harmonious balance in the sound image, enhancing the overall experience factor of the speaker.
