Frequently Asked Questions about HMS 10 B-2

What advantages does the 2-ohm configuration of the HMS 10 B-2 Marine-Subwoofer offer?

The 2-ohm configuration of the HMS 10 B-2 Marine-Subwoofer from Hertz allows for optimal use of amplifier power. This impedance enables the subwoofer to draw more current from the amplifier, resulting in a more powerful bass performance. Combined with main speakers, this ensures dynamic and robust audio playback. Especially in marine environments, where there are other acoustic challenges such as wind and water noise, this lower impedance can help highlight the bass and create an intense listening experience. For audiophiles seeking seamless integration and excellent sound performance, this subwoofer is an outstanding choice.

What is the power handling of the HMS 10 B-2 and what does this mean for its audio performance?

The HMS 10 B-2 features an RMS power handling of 250 watts and a peak power handling of 500 watts. These values demonstrate the subwoofer's ability to continuously reproduce high levels without distortion, ensuring clear and powerful bass even at maximum output. This power handling ensures that the subwoofer consistently delivers its audio performance even in demanding applications where high volume is necessary. Therefore, this subwoofer is ideally suited for loud outdoor events or on boats. It offers consistent sound fidelity and can meet extreme acoustic demands.

What durable materials does the HMS 10 B-2 use to withstand harsh marine conditions?

The HMS 10 B-2 from Hertz has been specifically designed for marine conditions. It utilizes a polypropylene diaphragm with UV inhibitors that protect against sunlight, as well as a Santoprene surround that is highly durable and resistant to saltwater. The advanced aramid fiber spider ensures consistent performance over time. By using silicone caps on gold-plated brass terminals, the connection is protected from corrosion due to salt mist and moisture. This choice of materials ensures that the subwoofer operates reliably even under harsh conditions and achieves consistent audio performance.

What are the dimensions of the HMS 10 B-2 and what should be considered during installation?

The HMS 10 B-2 Marine Subwoofer has a diameter of 250 mm and a mounting depth of 191 mm. The installation requires a cutout of 230 mm. When installing, it is important to pay attention to the depth of the enclosure and the space behind the installation location. The installation on board should prioritize secure mounting to withstand the effects of vibrations and movement. Its robust construction allows for installation even in exposed positions that are subject to vibrations. It is advisable to follow the included installation instructions carefully to achieve optimal performance.

What do the Xmax and Xmech values indicate for the bass performance of the HMS 10 B-2?

For the HMS 10 B-2, the Xmax value is 12.3 mm and the Xmech value is ±16.3 mm. These values describe the maximum displacement of the speaker and directly determine the Subwoofer's ability to reproduce low frequencies. Xmax is the linear displacement range in which the diaphragm moves smoothly without introducing distortion. Xmech refers to the maximum mechanically usable travel of the diaphragm. Higher values allow for more powerful bass reproduction, as the diaphragm can move larger volumes of air, thus producing deeper bass. These parameters ensure that the HMS 10 B-2 generates a deep, powerful sound even at high volumes.

What role does the voice coil play in the HMS 10 B-2 and what are its technical specifications?

The HMS 10 B-2 uses a 50 mm voice coil, which is crucial for the performance and durability of the Subwoofer. This size of the single voice coil allows for high thermal resilience, meaning it can convert more energy from electrical signals into mechanical vibrations without overheating. Even in demanding situations, it provides excellent control over diaphragm movement, resulting in clear and precise bass. The high-quality manufacturing of the voice coil from materials designed for high current flow ensures that the Subwoofer maintains its performance even under extreme conditions.

How does the HMS 10 B-2 differ in its construction from standard Subwoofers?

Unlike standard Subwoofers, the HMS 10 B-2 has been specifically designed for use in marine environments. It features a FEM-optimized, highly mobile magnetic drive unit, enclosed in a robust marine-grade polymer basket that is also resistant to splashes. The housing is vibration-resistant and protects the components from salt mist, dust, and thermal shock. The materials used and the construction are chosen to withstand both mechanical stress and environmental influences. These differences make it more durable and reliable under conditions that would be challenging for conventional speakers.

Why are the gold-plated brass connectors important for the HMS 10 B-2?

The gold-plated brass connectors of the HMS 10 B-2 play a crucial role in the reliability and performance of the Subwoofer. Gold-plated connectors minimize the possibility of corrosion, which can occur in marine environments due to moisture and salt mist. These connectors provide improved electrical conductivity and ensure that power loss remains minimal, which in turn optimizes audio performance. Together with the silicone caps that further protect the connection points from penetrating water, these connectors offer long-term and trouble-free operation, even in the most challenging nautical conditions.

What do the Thiele Small parameters of the HMS 10 B-2 mean for sound quality?

The Thiele Small parameters of the HMS 10 B-2, such as Fs 43 Hz, Vas 30.46 l, and Qts 0.6, provide detailed insights into the performance and sound characteristics of the Subwoofer. Fs, the resonance frequency, is relatively low at 43 Hz, allowing for a deep bass sound. Vas indicates that the effective air volume displacement is 30.46 liters, suggesting a flexible box tuning. The Qts value of 0.6 indicates a controlled transient response, ideal for precise and natural bass reproduction. These parameters are crucial for tuning the enclosure design and optimizing the overall audible sound quality.

How does the frequency response of the HMS 10 B-2 behave in sealed enclosures?

The HMS 10 B-2 is optimized for use in a sealed enclosure, which affects the frequency response. With an enclosure volume of 71 liters (2.51 cu ft.), an Fb of 51 Hz and a Qtc of 0.99 are achieved. This means that the Subwoofer delivers a smooth roll-off curve with precise bass, ideal for clear and uncolored sound reproduction. Sealed enclosures support the transient response through targeted insulation, making the bass appear denser without distortion. This configuration is particularly suitable for applications where accurate bass control is a priority and closed enclosure conditions are preferred.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.
