Frequent questions about HMS 10 B-2

Welche Vorteile bietet die 2-Ohm-Konfiguration des HMS 10 B-2 Marine-Subwoofers?

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. In combination with main speakers, this ensures dynamic and powerful 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.

Wie ist die Belastbarkeit des HMS 10 B-2 und was bedeutet dies für seine Audioleistung?

The HMS 10 B-2 is characterized by an RMS power handling of 250 watts and a peak power handling of 500 watts. These values demonstrate the subwoofer's ability to reproduce high levels continuously 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.

Welche langlebigen Materialien verwendet der HMS 10 B-2, um den harschen maritimen Bedingungen standzuhalten?

The HMS 10 B-2 from Hertz was specifically designed for maritime conditions. It utilizes a polypropylene membrane 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 connection terminals, the contact is protected from corrosion caused by salt mist and moisture. This choice of materials ensures that the subwoofer operates reliably even under harsh conditions and delivers consistent audio performance.

Welche Abmessungen hat der HMS 10 B-2 und worauf sollte man bei der Installation achten?

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 trim and the space behind the installation location. The installation on board should emphasize secure fastening to withstand the effects of vibrations and movement. The robust construction allows for mounting even in exposed positions that are subject to vibrations. It is advisable to follow the included installation instructions carefully to achieve optimal performance.

Was bedeutet die Angabe der Xmax und Xmech Werte beim HMS 10 B-2 für die Bassleistung?

In 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 is capable of moving larger volumes of air, thus producing deeper bass. These parameters ensure that the HMS 10 B-2 generates a deep, powerful sound image even at the highest volumes.

Welche Rolle spielt die Schwingspule beim HMS 10 B-2 und was sind ihre technischen Spezifikationen?

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 the 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 consistently even under extreme conditions.

Wie unterscheidet sich der HMS 10 B-2 in seiner Konstruktion von Standard-Subwoofern?

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 stresses and environmental influences. These differences make it more durable and reliable under conditions that would be challenging for conventional speakers.

Warum sind die vergoldeten Messinganschlüsse beim HMS 10 B-2 wichtig?

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.

Was bedeuten die Thiele Small Parameter des HMS 10 B-2 für die Klangqualität?

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.

Wie verhält sich der Frequenzgang des HMS 10 B-2 in versiegelten Gehäusen?

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.), a 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 damping, 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.

Massive MiniMonster!

What a Minimonster, 18Liter ported box,tuned to 32hz and plays very loud and even good on lows. Even when i'm underpowering and only giving 350-400watts max. I really love this 6,5 monster, also the aluminium basket is very strong and solid and has great venting for the voice coil. Having rubber surround and carbon fiber cone just makes this even more indestructible

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.
