The HMS 10 B4-LD-W from Hertz is extremely resistant to various environmental influences thanks to its high-quality materials. It withstands UV rays, salt mist, vibrations, water spray, thermal shock, and dust. These resistances make it ideal for applications in marine environments where conventional speakers quickly reach their limits. The robust design ensures that the subwoofer maintains its functionality and sound quality even under extreme conditions, which is particularly beneficial for boat owners.

Welche physikalischen Eigenschaften hat der HMS 10 B4-LD-W und welche Bedeutung haben sie?

The HMS 10 B4-LD-W has compact dimensions of 250 mm in size and a depth of 191 mm, allowing for versatile installation. Its weight of 5.1 kg ensures that the unit remains stable in its position and thus operates with low resonance. Its robust housing, with dimensions of 440 x 440 mm and a wood thickness of 19 mm, additionally ensures that the generated sound remains free from cabinet resonances, while the polymer housing provides protection against the demands of the maritime environment.

Welche Thiele-Small-Parameter besitzt der Hertz HMS 10 B4-LD-W?

The HMS 10 B4-LD-W subwoofer has the following Thiele-Small parameters: Its re-impedance is 2.1 ohms, while the resonance frequency (Fs) is at 43 Hz. The equivalent volume (Vas) is 30.46, which, in conjunction with an effective diameter (D) of 210 mm, allows for efficient deep bass reproduction. Its mechanical displacement (Xmax) is 12.3 mm. Other electromechanical values such as Qts of 0.6 and BL of 8.3 T*m ensure a balanced and powerful bass reproduction.

Wie sieht die Gehäusekonfiguration des HMS 10 B4-LD-W aus?

The HMS 10 B4-LD-W subwoofer is particularly suitable for sealed box applications. A volume of 50 liters (1.77 cu.ft.) is required for a compact enclosure with a resonance frequency (Fb) of 54 Hz. For larger enclosures, the recommended volume is 71 liters (2.51 cu.ft.) with a lower Fb of 51 Hz. This adaptability ensures optimal performance in varying space availability and sound preferences. The recommended wood thickness for the enclosure is 19 mm, and the specific panel cutting measures are provided in detail.

Welche Materialien werden beim HMS 10 B4-LD-W verwendet und warum?

The Hertz HMS 10 B4-LD-W uses a combination of durable materials specifically designed for harsh conditions. The cone is made of polypropylene treated with UV inhibitors to minimize sun damage. The progressive aramid fiber spider, combined with silicone-insulated connection wires, ensures a long lifespan and consistent performance. The magnet is made of high-density ferrite, which, in conjunction with a polymer-encapsulated basket, ensures structural integrity even under the most demanding marine conditions.

Wie ist die Schwingspule des HMS 10 B4-LD-W ausgelegt?

The voice coil of the HMS 10 B4-LD-W from Hertz is designed as a single voice coil with a diameter of 50 mm. This design allows for handling significant output power while optimally controlling the movements of the cone. Its construction is FEM-optimized, meaning it has been designed using finite element methods to maximize efficiency and durability even at high sound pressure levels. The voice coil helps to maintain the structural integrity and sound fidelity of the subwoofer.

Welche besonderen Konstruktionsmerkmale hat der HMS 10 B4-LD-W?

The HMS 10 B4-LD-W from Hertz features a number of special design characteristics, including a FEM-optimized mobile unit for high displacements and a massive magnetic group for improved performance. The injected basket is made of marine-grade polymer material that is both structurally stable and weather-resistant. Gold-plated brass connection terminals, which are corrosion-resistant and have a silicone cap, protect the connection point from environmental influences. All of these design elements contribute to the exceptional performance of the device.

Welche elektro-akustischen Spezifikationen bietet der Hertz HMS 10 B4-LD-W?

Electro-acoustically, the HMS 10 B4-LD-W offers specified characteristics such as a total displacement (Xmech) of ±19 mm, a maximum mechanical displacement (Xmax) of 12.3 mm, and a sound pressure level (Spl) of 88.5 dB. Its inductance (Le) is 0.46 mH, while the moving mass (Mms) reaches 75.6 g. Dynamic parameters such as the compliance (Cms) of 0.18 mm/N and the mechanical quality (Qms) of 12.3 make the system efficient and well-suited to different bass requirements. The Qes value of 0.63 also supports a fine balance between electrical and acoustic efficiency.

Wie installiere ich den Hertz HMS 10 B4-LD-W in meinem Boot?

When installing the HMS 10 B4-LD-W from Hertz, one should focus on the installation dimensions and the specific environment on board the boat. The subwoofer installation depth is 191 mm, and the mounting diameter is 277 mm.

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 .

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.
