The HMX 8-TC from Hertz offers an RMS power of 100 watts and can achieve peak power of up to 200 watts. This robustness makes it an ideal companion for use in maritime environments, where high sound quality is required under changing conditions. The speaker is equipped with a 32 mm voice coil, which, along with the high-quality polypropylene diaphragm, ensures precise sound reproduction. Stability and efficiency in power transmission are ensured by gold-plated, corrosion-resistant terminals that guarantee durability and lasting audio performance.
The HMX 8-TC from Hertz features a wide frequency response of 45 Hz to 25 kHz. This frequency range allows the speaker to reproduce both deep bass and high tones clearly and precisely. The use of neodymium magnets in the tweeter contributes to the clarity of the high frequencies, while the flux ferrite magnet of the woofer ensures that the lower frequency ranges are not compromised. This technical characteristic is supported by the perfectly tuned voice coil, which has been specifically designed for infinite baffle applications.
The HMX 8-TC speaker is equipped with a polypropylene membrane that is protected by UV inhibitors, contributing to its durability in a marine environment. This design ensures resistance to damaging elements such as water, dust, and UV rays. The aramid fiber spider and the silicone-insulated connection wires enhance mechanical stability and sound quality over extended periods. These high-quality materials are crucial for use in challenging environmental conditions, as encountered in the marine environment.
The HMX 8-TC Marine speaker from Hertz has a diameter of 200 mm, which is approximately 8 inches. The constructive dimensions also include a mounting depth of 123 mm. These generous dimensions allow for an extended sound pressure level and are beneficial for acoustic performance. When installing, it is important to consider the physical specifications to ensure a correct installation. The dimensions allow for integration into various installation locations, provided there is enough space for insertion.
The Thiele Small parameters of the HMX 8-TC include a Vas of 29.46 L, a total Qts of 0.58, and a mechanical Qms of 11. With a resonance frequency Fs of 50 Hz and a moving mass value Mms of 27.3 g, the speaker allows for precise low-frequency output. These parameters are essential for predicting the performance of the speaker in various enclosure types and acoustic environments. The Bl parameter of 6.6 T*m represents the effectiveness of the interaction between the magnetic field and the voice coil and contributes to the efficiency of converting electrical energy into acoustic signals.
The HMX 8-TC from Hertz is preferably installed in locations exposed to a marine environment, with attention to a secure mounting. It is important to position the speaker so that the 123 mm installation depth and the 200 mm diameter are taken into account. The installation environment must also ensure access to the gold-plated terminals to enable a reliable connection of the speaker terminals. The use of a dense mounting body, such as injected polymer, promotes protection against splashes and increases the overall lifespan of the installation.
The HMX 8-TC from Hertz is optimized for its off-axis radiation, contributing to a superior sound pressure level. The 36 mm tweeter ensures detailed high-frequency presence, while the 32 mm woofer with long-stroke capability delivers powerful bass. With an Xmech of ±8.5 mm, the speaker can handle large mechanical displacements without losing sound integrity. These acoustic features are particularly advantageous in open environments such as on boats, where it is important that the sound characteristic is not influenced by the speaker's position relative to the listener.
The HMX 8-TC is specifically designed for maritime use and is protected against water, UV radiation, temperature fluctuations, and corrosion due to its materials. The polypropylene membrane with UV inhibitors and the acoustic lens optimize protection against environmental influences, while the tone-on-tone high-frequency grid made of stainless steel provides resistance to salt mist. Gold-plated terminals prevent corrosion at the connection points. These technical features ensure that the HMX 8-TC offers a long lifespan and consistently high audio quality even in harsh, saline environments.
With a sound pressure level of 91 dB, the HMX 8-TC from Hertz offers above-average performance output compared to other speakers of similar size and price range. This high SPL value (Sound Pressure Level) results from the combination of materials such as the neodymium magnet in the tweeter and the polypropylene diaphragm in the woofer. Maximizing sound efficiency is important in marine applications, where the speaker can be drowned out by ambient noises like wind and waves. Thus, the HMX 8-TC ensures that the sound remains clear and uncolored even at high volumes.
The HMX 8-TC from Hertz has an impedance of 4 ohms. This impedance design allows the speaker to be efficiently operated with most amplifiers designed for 4-ohm speaker systems. A lower impedance means that the speaker draws more current at the same amplifier power level, which can lead to a more powerful sound. Impedance is a critical specification feature that ensures the speaker is compatible with existing systems, thereby achieving the best possible performance without distortion or loss of power.
