What are the electro-acoustic specifications of the Hertz HMS 10 B4-LD-C?

The electro-acoustic specifications of the Hertz HMS 10 B4-LD-C Subwoofer include important values for sound characteristics. The value for D is 210 mm and the maximum displacement (Xmax) is 13.5 mm. The electrical resonance frequency (Fs) is 41 Hz, while the Re (AC resistance) is 4.5 Ohms. The coil inductance value (Le) is 0.9 mH. Other specifications include the mechanical equivalent volume (Vas) of 37 l, the moving mass (Mms) of 69 g, and the force factor (BL) of 10.2 T*m. These specifications are crucial for the precise and deep bass reproduction of the Subwoofer.

Are there specific Thiele/Small parameters for the HMS 10 B4-LD-C?

The Hertz HMS 10 B4-LD-C Subwoofer provides a detailed specification of Thiele/Small parameters that are essential for the accurate tuning of speaker enclosures. The Qts value is 0.71, which indicates balanced damping. The Qms value is 11, and the Qes value is 0.76. With a Vas of 37 liters and an SPL of 88 dB, the Subwoofer is optimized for extremely responsive and deep bass reproduction. These parameters assist in the precise adjustment of the Subwoofer to individual acoustic requirements and enclosure configurations.

What enclosure data is important for the installation of the HMS 10 B4-LD-C?

When installing the Hertz HMS 10 B4-LD-C, it is crucial to consider the enclosure data. For the sealed box design, the volume is 50 liters (1.77 cu.ft.), with a tuning frequency (Fb) of 54 Hz and a Qtc of 1.05. The dimensions W (width), H (height), and D (depth) are 440 mm, 440 mm, and 365 mm. The mounting holes with a diameter of 230 mm are important. When integrating this Subwoofer into your system, these specifications should be observed to ensure optimal sound quality.

How challenging is the installation of the Hertz HMS 10 B4-LD-C in the vehicle?

The installation of the Hertz HMS 10 B4-LD-C Subwoofer in the vehicle requires some technical considerations regarding the installation dimensions. The component has a diameter of 250 mm and a mounting depth of 116 mm. It is important that the installation location is carefully planned to ensure sufficient space for the magnet size of 140 x 60 x 30 mm. Proper placement is crucial to prevent unwanted resonances or vibrations from affecting sound clarity. A precisely fitted, sealed box can help fully utilize the Subwoofer's performance.

What is the maximum Xmech of the Hertz HMS 10 B4-LD-C Subwoofer?

The Hertz HMS 10 B4-LD-C Subwoofer has a maximum mechanical stroke (Xmech) of ±19 mm. This parameter is critical for the movement of the diaphragm, especially during intense bass playback. The Xmech value indicates the maximum degree of displacement the diaphragm can achieve before distortion may occur or mechanical limits are exceeded. A value of ±19 mm represents high flexibility of diaphragm movement, which contributes to producing powerful and clear bass frequencies, especially at high power levels.

What material properties does the diaphragm of the Hertz HMS 10 B4-LD-C have?

The diaphragm of the Hertz HMS 10 B4-LD-C Subwoofer is made of polypropylene, to which UV inhibitors have been added. Polypropylene is known for its rigidity and durability, making it ideal for use in subwoofers that are subjected to heavy demands. The UV inhibitors prevent the material from degrading over time due to sunlight or other environmental influences. This material thus ensures consistent performance and reduces the risk of discoloration or structural damage over the product's lifespan.

How does the ferrite magnet affect the performance of the HMS 10 B4-LD-C?

The ferrite magnet of the Hertz HMS 10 B4-LD-C is crucial for its performance. With dimensions of 140 x 60 x 30 mm, the magnet creates a strong magnetic field around the voice coil, which is necessary to move the diaphragm precisely. This magnet size allows for efficient energy conversion, which is required to reproduce high volumes without distortion. Ferrite magnets are also known for their thermal stability, meaning they do not quickly lose their magnetic properties under intense use.

What is the overall load capacity of the HMS 10 B4-LD-C?

The Hertz HMS 10 B4-LD-C is impressive in terms of its load capacity. It offers a continuous load capacity of 300 watts RMS and can handle peak loads of up to 600 watts. This makes it ideal for applications where both sustained performance and the ability to maintain high sound quality during short peak loads are required. These specifications ensure that the subwoofer can produce clean playback even at high volumes and demanding bass frequencies.

What are the Q values of the Hertz HMS 10 B4-LD-C and what do they mean?

The Hertz HMS 10 B4-LD-C has specific Q values that characterize its acoustic performance. Qts, the total quality factor, is 0.71, indicating a balanced resonance. Qms, the mechanical quality factor, is 11, while Qes, the electrical quality factor, is 0.76. Qts affects the overall sound of the subwoofer, Qms relates to mechanical damping, and Qes pertains to electrical damping. These values are important for designing and tuning an appropriate speaker enclosure to achieve optimal sound.
