Frequently Asked Questions about HMS 12 B2-LD-C

What are the performance specifications of the HMS 12 B2-LD-C Subwoofer?

The HMS 12 B2-LD-C Subwoofer from Hertz offers impressive performance specifications, including an RMS continuous power handling of 500 watts and a peak power handling of 1000 watts. The impedance is 2 ohms, and the subwoofer features a long-stroke design, allowing for high linear displacement with low distortion. The voice coil diameter is 65.5 mm, contributing to efficient heat dissipation and power absorption. These technical features enable the subwoofer to deliver deep bass with high precision and pressure, ideal for outdoor applications. With a sensitivity of 89.5 dB and a resonance frequency of 30 Hz, the subwoofer is optimized for a powerful bass experience.

How does the HMS 12 B2-LD-C affect bass reproduction in an audio system?

The HMS 12 B2-LD-C significantly enhances bass reproduction by relieving the main speakers and creating a more dominant low-end effect. This is due to the high linear stroke and low distortion of the subwoofer. Its ability to reproduce powerful bass at a resonance frequency (Fs) of 30 Hz ensures a deep and dynamic sound profile. The polypropylene cone with UV inhibitors helps optimize sound performance against external weather influences, while the magnet system made of high-quality ferrite is designed to ensure consistent and stable sound reproduction. These features make the subwoofer particularly effective in marine applications.

What are the installation requirements for the Hertz HMS 12 B2-LD-C?

The installation of the Hertz HMS 12 B2-LD-C should be carried out as planned to achieve optimal sound results. With a depth of 191 mm and a cutout opening of 300 mm in diameter, it is essential to find a suitable location for installation. The physical dimensions of the subwoofer, such as A = 342.9 mm, B = 279.4 mm, and C = 192.8 mm, are important for correctly determining the installation site. The adaptability through the HM RGB 1 BK also allows for visual customization of the subwoofer to match the environment, while the optional RGB controller set further enhances the user experience. Thoughtful placement and utilizing the full installation depth will yield highly effective results.

What materials are used for the HMS 12 B2-LD-C?

The HMS 12 B2-LD-C from Hertz features a polypropylene membrane with UV inhibitors that provide durability and protection against sunlight. The magnet made of high-density flux ferrite is designed to maintain magnetic force and support precise movements of the membrane. Weighing 7.6 kg, the Subwoofer also provides a structurally stable foundation. The voice coil with a diameter of 65.5 mm contributes to performance reliability by efficiently distributing the heat generated. This combination of materials supports a long-lasting and weather-resistant design suitable for outdoor applications.

What are the electro-acoustic specifications of the HMS 12 B2-LD-C?

The electro-acoustic specifications of the HMS 12 B2-LD-C are crucial for its performance. These include a Qts value of 1, which describes the total quality, and a Qes value of 1.1, which indicates the electrical quality. The Vas of 95.4 liters indicates how much air volume is effectively moved by the Subwoofer. The Mms value of 114 grams describes the mechanical mass of the oscillating system and affects the response speed to low frequencies. The BL value of 8 T*m is an indicator of the strength of the magnetic field in relation to the voice coil. Finally, the Xmax of 19 mm is a measure of the maximum linear excursion.

What are the dimensions and installation depth of the HMS 12 B2-LD-C?

The dimensions of the HMS 12 B2-LD-C include a diameter of 300 mm for the membrane with an outer size of 342.9 mm. The installation depth is specified as 191 mm, with the required mounting hole needing a diameter of 279.4 mm. Specific installation measurements such as C = 192.8 mm, D = 140.6 mm, and F = 52.2 mm should also be noted. This detailed alignment of dimensions is crucial for seamless installation in marine applications. The total weight of 7.6 kg ensures that the Subwoofer remains securely and vibration-free in the intended installation.

What role does the magnet system and voice coil design play in the HMS 12 B2-LD-C?

The magnet system of the HMS 12 B2-LD-C consists of high-density flux ferrite, which is critical for the efficiency and performance of the Subwoofer. The large voice coil with a diameter of 65.5 mm ensures precise motion control and better heat management capabilities during intense use. This combination reduces distortion and allows for powerful, clear bass sound. Especially with large membrane areas, such a robust magnet system is essential to ensure the necessary linearity of the membrane movement at high volumes without signal distortion.

How does the LED lighting affect the application of the HMS 12 B2-LD-C?

The LED lighting of the HMS 12 B2-LD-C, controlled by the HM RGB 1 BK, offers an optical adaptation to the environment or mood, which is particularly relevant for outdoor applications. This feature integrates seamlessly with the performance capacity of the Subwoofer, without compromising it. The RGB controller allows for changing colors, enabling you to create visual effects that stand out impressively in your audio setup. Despite the aesthetic enhancement, the acoustic performance of the Subwoofer remains unaffected, as the LED components are engineered to have no negative impact on sound quality.

What is the sensitivity of the HMS 12 B2-LD-C and what does it mean for performance?

The sensitivity of the HMS 12 B2-LD-C is 89.5 dB, which represents a medium to high sensitivity in Subwoofer technology. This parameter indicates how efficiently the Subwoofer converts electrical signals into sound pressure. At 89.5 dB, this means that the Subwoofer is capable of generating a high level of volume from a relatively low power input. For the user, this means that the Subwoofer can produce impressive bass even in lower-powered audio systems without requiring significant amplifier power, which is especially beneficial for mobile installations or smaller boat systems.

What factors contribute to the suitability of the HMS 12 B2-LD-C for outdoor applications?

The suitability of the HMS 12 B2-LD-C for outdoor applications is based on several technical aspects. The large linear excursion of 19 mm ensures deep, powerful bass even without a housing. The UV-resistant polypropylene diaphragm is resistant to sunlight, while the high-density flux ferrite magnet system ensures lasting stability and sound precision. Additionally, the Subwoofer is specifically designed for open environments, as highlighted by its ability to deliver excellent performance even at low resonance frequencies of 30 Hz. These features make it ideal for use in open areas such as boats or outdoor party spaces.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
