Marine coaxial speakers with robust design and off-axis optimization

Hertz's 165 mm coaxial speaker was specifically designed for marine applications and can withstand extreme conditions such as UV rays, salt spray, and humidity. The UV-resistant polypropylene cone with a co-molded Santoprene surround provides resistance to external influences, while the system's off-axis optimization ensures maximum sound pressure levels. This delivers stable, high-precision sound, ideal for open environments. A less robust cone would degrade over time, reducing sound quality. The integration of the acoustic lens also supports the wide dispersion of the sound.

High-performance tweeter with neodymium magnet and optimal sound pressure level

The 1.4-inch neodymium magnet tweeter is the heart of the HMX 6.5-LD-TC, delivering precise highs with a frequency response of up to 25 kHz. The neodymium magnet delivers superior energy generation for the 20 mm tweeter, while the PEI dome minimizes distortion. The combination of the front panel and acoustic lens ensures the best off-axis dispersion and high sound fidelity. Without the powerful tweeter cone, the high-frequency range would not be as detailed. Competing products often lack this quality enhancement, which can lead to limited high-frequency reproduction.

Frequency response and electroacoustic specifications of the HMX 6.5-LD-TC

A key feature of the HMX 6.5-LD-TC is its exceptionally wide frequency response from 50 Hz to 25 kHz, which clearly reproduces both low and high frequencies. The resonant frequency Fs at 65 Hz enables powerful bass, while the SPL of 89 dB ensures the speaker can perform impressively even in noisy environments. Reducing these frequencies would result in a loss of broad sound coverage. Parameters such as Qts of 0.7 and Bl of 5.2 T*m offer a balance between efficiency and bass performance—factors that set the HMX 6.5-LD-TC apart from many other speakers.

Thiele small parameter analysis and effects on sound characteristics

Thiele-Small's parameters, such as the Vas of 8.8 liters and the mechanical quality factor Qms of 11.5, are crucial for use in infinite baffles. The DC resistance Re of 3.5 ohms and the voice coil inductance Le of 0.53 mH support electrical stability and reduce the risk of interference. A lower Bl value would result in weaker bass, while the increased range of motion provided by the Xmech of ±6.65 mm enables impressive dynamic range when playing music. These specifications guarantee consistent and long-lasting performance, even under constant load.

Optimized woofer magnets and voice coil for improved sound depth

The 25 mm long-throw woofer specializes in impressive bass reproduction. Driven by a high-density flux ferrite magnet combined with the aramid fiber-reinforced spider, it delivers powerful yet precise bass. The advantage of high-temperature voice coil resistance is its ability to support high loads without compromising electrical capacity. A smaller voice coil diameter could reduce sensitivity and lead to increased distortion, which would compromise the desired rich sound.

RGB LED lighting for visual accents and a wide range of accessories

The built-in RGB LED lighting of the HMX 6.5-LD-TC, combined with the HM RGB 1 BK accessory, offers not only sound but also a lighting experience that dances to the rhythm of the music.
