Optimal off-axis dispersion thanks to 36 mm neodymium tweeter with acoustic lens

The Hertz tweeter impresses with its off-axis dispersion, optimized by an acoustic lens. With a 36 mm dome and a powerful neodymium magnet, it achieves a maximum sound pressure level that delivers brilliant high-frequency detail. With a sound pressure level of 89 dB, it ensures that every detail is preserved, even in loud ambient noise. A lower sound pressure level could result in loss of more lossless details, which is something to consider when making your purchase decision.

UV-resistant polypropylene membrane and its durability properties

The membrane of the HMX 6.5 S-LD Powersport is made of UV-resistant polypropylene. This construction is essential for use in marine environments, as it protects against harmful rays and maintains material integrity for years. Comparatively weaker UV protection could lead to rapid discoloration and compromised membrane performance.

Special performance at 125 mm D and 3.65 mm Xmax

With an effective cone area (D) of 125 mm and a maximum diaphragm excursion (Xmax) of 3.65 mm, the speaker can produce extreme levels without distortion in any music playback. This ensures deep bass and pristine sound reproduction. A lower Xmax value would limit the bass range and lead to distortion at high volumes.

Resonance frequency (Fs) of 65 Hz for detailed sound reproduction

The resonant frequency of 65 Hz is ideal for use in ships or vehicles, as it allows for deep bass reproduction without the need for additional subwoofers. A higher resonant frequency would curtail the bass range, which would be undesirable for bass-intensive music styles.

Neodymium tweeter magnetic properties at 19.7 x 3 mm

The neodymium tweeter magnet, measuring 19.7 x 3 mm, combines small size with high energy efficiency. Thanks to its excellent magnetic properties, it produces powerful, clear high-frequency tones. A smaller magnet would reduce energy efficiency and potentially negatively impact sound quality.

FEM-optimized for high deflections: Advantages of the Hertz design

The entire loudspeaker is FEM-optimized, meaning the structures are designed for both high sound levels and durability. Non-optimized excursion could lead to mechanical damage that would impair sound reproduction.

Integrated RGB LED lighting for visual experiences

This unit is equipped with integrated RGB LED lighting, enhancing the visual experience. The RGB LEDs transform any audio experience with their harmonious lighting effects. An essential component is the HM RGB 1 BK RGB controller accessory , which offers a wide range of lighting effects.

Moving mass (Mms) of 14 g is significant

The moving mass of the system, specified at 14 g, has a significant impact on bass reproduction. A lower Mms value could result in poor low-frequency performance, while a higher Mms value compromises responsiveness and thus sound quality.

Electro-acoustic specifications such as Qts at 0.7 for optimal performance

A Qts of 0.7 means the device is suitable for wideband environments, achieving a balance between bass and clarity. A higher Qts value would expand the bass at the expense of overall bandwidth, while a lower Qts would have the opposite effect.

Gold-plated, corrosion-resistant terminals for secure connections

The use of gold-plated, corrosion-resistant terminals guarantees a long-lasting, stable connection to all connected devices. This is especially essential in saltwater environments to prevent signal loss and corrosion. A non-gold-plated connector could lead to unstable connections and corrosion-related failures.

Installation dimension 95.6 mm for flexible installation options

With a mounting depth of 95.6 mm, the speaker is versatile and can be installed in most modern marine or powersport systems. A larger mounting depth would often be problematic in terms of space in tight spaces and could complicate installation. Installation on-site in Frankfurt (Oder) to maximize performance.
