The lighting can be tailored to the specific mood or activity, further increasing the maritime experience factor.
The 6.5-inch form of the HMX 6.5 S-LD-G is ideal for both high-frequency playback and solid bass tones. The combination of a 165 mm woofer and a compact tweeter allows for a balanced sound distribution. The dimensions, along with a frequency response between 50 Hz and 25 kHz, ensure that the speaker can produce a full spectrum of musical details, making every note sound clear and voluminous. Music lovers who appreciate versatility particularly benefit from this design.
The HMX 6.5 S-LD-G is characterized by a variety of technical details that specify its performance. The mechanical compliance value Cms is 0.4 mm/N, indicating the flexibility of the speaker. The electrical loss resistance Re is set at 3.5 Ohms. The mechanical loss factor Qms is 11.5, which affects the mechanical damping of the system. With a total mass (Mms) of 14 g, the speaker is perfectly optimized for efficiency. These parameters lay the foundation for excellent sound performance at sea.

Size and installation of the Hertz HMX 6.5 S-LD-G for perfect sound integration on boats

With a diameter of 165 mm, the Hertz marine coaxial speaker offers an ideal balance between compactness and rich sound. The mounting depth of 95.6 mm allows for easy installation on various boat types. A paintable sports grille ensures seamless integration while protecting the speaker's electronics from the elements. Imagine how this combination of design features enhances the aesthetic appearance of your sporty boat while taking sound quality to a new level. A deeper mounting depth would limit the possible applications, while a larger size could compromise available space. This balanced diameter is perfectly suited for most marine applications.

Performance characteristics of the Hertz HMX 6.5 S-LD-G: Power handling and impedance in detail

The Hertz Marine Speaker offers an RMS power handling of 75 watts and a maximum power handling of 150 watts, making it ideal for powerful outdoor audio applications. This power ensures virtually no loss in sound quality, even at high speeds on the water. With an impedance of 4 ohms, the speaker is optimized to work with both standard and custom amplifiers. These values ​​are highly valued in the marine industry as they represent a balance between performance and energy efficiency. A higher RMS value would undoubtedly provide even greater acoustic power handling, while a lower impedance could place greater strain on the amplifier.

Frequency response of the Hertz Marine Coaxial Speaker: From deep bass to ultra-sharp treble

With a frequency range of 50 Hz to 25 kHz, this speaker redefines sonic precision, capturing both thumping lows and crystal-clear highs. This range makes it perfectly suited for all musical genres one would want to enjoy in a marine environment. A wider frequency range sets a standard in sound reproduction, while a narrower bandwidth could limit the dynamic qualities of the listening experience. Coverage of these frequencies is particularly appreciated in real-world use on open waters, where the sound of the sea can be a natural enemy of clarity. This specified frequency continuity sets the speaker apart from competing products with more limited bandwidths.

Membrane and magnetic materials: UV-resistant polypropylene and high-quality magnets

The use of UV-resistant polypropylene for the cone ensures that the speaker offers long-lasting performance even under constant sunlight. The use of a high-performance flux ferrite magnet in the woofer and a neodymium magnet in the tweeter supports the speaker's powerful yet precise sound. This combination of materials ensures durability and sound fidelity, which is particularly crucial in harsh maritime environments. Lesser resistance of these materials would lead to faster deterioration under UV light and impair sound quality. This special material concept clearly sets the HMX 6.5 S-LD-G apart from its competitors, who cannot maintain similar performance values ​​over the long term.

Thiele-Small parameters of the HMX 6.5 S-LD-G: Electromechanical properties in focus

The Hertz loudspeaker boasts impressive Thiele-Small parameters, such as a resonance frequency Fs of 65 Hz and a Vas of 8.8 liters, ensuring an ideal balance between bass reproduction and cabinet size. Its Qts of 0.7 demonstrates that it performs excellently in a sealed or vented enclosure. The Bl of 5.2 T*m supports the speaker's efficiency and promotes a powerful bass response. A Qts below 0.5 would be preferable for sealed enclosures, while higher values ​​could result in less control in the bass range. These precise parameters allow you to exploit the speaker's full acoustic potential in various installation configurations.

True technical precision: Diameter and voice coil details in the HMX 6.5 S-LD-G from Hertz

The Hertz loudspeaker impresses with its 25 mm woofer voice coil and a 20 mm tweeter voice coil. This dimension supports robust music reproduction at both low and high frequencies. Combined with a 36 mm tweeter cone diameter, it offers an ideal blend of sound clarity and depth. A smaller voice coil tends to impair heat dissipation, which could lead to excessive thermal stress. These specified dimensions provide exceptional sound quality with even energy distribution and prevent sonic distortion. In the market for comparable units, these dimensions set a benchmark for consistency and durability.

Impedance of the Hertz HMX 6.5 S-LD-G optimized for best sonic performance on the open sea

With an impedance of 4 ohms, this speaker is perfectly tuned for power. This impedance facilitates efficient energy flow from the amplifier to the speaker, which is especially beneficial at high volumes. A lower impedance would result in higher power consumption and potential overheating problems, while a higher impedance could reduce volume and dynamic range. The 4 ohm impedance is a proven standard in the car and marine audio industry, striking a balance between energy efficiency and sonic power.

RGB LED accessories for the Hertz HMX 6.5 S-LD-G: Visual highlights

The optional RGB LED accessory HM RGB 1 BK provides lighting effects that can transform your speaker into a colorful visual highlight on your boat. The RGB controller with RF remote control allows you to create different mood lighting settings depending on your preferred environment. This accessory not only enhances the speaker's visual presence but can also be specifically tailored to different occasions. A missing LED option would not provide this visual effect and would detract from the overall ambiance of your boating experience.
