Häufige Fragen zum HMS 10 S2-LD-SW

What is the power rating of the HMS 10 S2-LD-SW Subwoofer?

The HMS 10 S2-LD-SW from Hertz is designed to achieve a maximum RMS power handling of 250 watts and a peak power handling of 500 watts. This high power rating allows the Subwoofer to produce powerful bass without overheating or distorting. Additionally, it has an acceptable impedance of 2 ohms, ensuring efficient power usage. Thanks to these specifications, you can expect clear and distortion-free sound reproduction even at high volumes, which is particularly beneficial for outdoor events or celebrations on your boat.

What are the dimensions of the HMS 10 S2-LD-SW and how is the installation?

The size of the HMS 10 S2-LD-SW is 250 mm in diameter, with a depth of 191 mm. For optimal mounting, a cutout size of 230 mm is required. Moreover, the dimensions of the Subwoofer are designed to fit perfectly into a sealed box measuring 440 mm x 440 mm x 365 mm (for a compact enclosure). It is important to adhere to the correct panel cutting list, especially with a wood thickness of 19 mm. If you have more space, a performance-oriented box measuring 460 mm x 460 mm x 450 mm is also suitable.

How does the removable sport grill with LEDs work on the HMS 10 S2-LD-SW?

The removable sport grill of the HMS 10 S2-LD-SW is equipped with integrated LED lighting, allowing you to customize the aesthetics of the Subwoofer. Especially when you are often on the water in the evening, the LEDs provide an impressive light show. With the optional HM RGB 1 BK accessory, which includes a remote control for creating a light show, you can synchronize the lighting to the music tempo or match the light color to the design of your boat. This feature significantly enhances the visual impact of the sound system.

What role does the voice coil play in the HMS 10 S2-LD-SW?

The HMS 10 S2-LD-SW features a voice coil with a diameter of 50 mm, allowing for efficient current conduction and optimal membrane movement. This specification is crucial for the performance of the Subwoofer, as a larger diameter can effectively dissipate more heat, enabling longer high-performance operations. Combined with the strong flux ferrite magnet, the voice coil ensures precise control of the membrane movement to deliver distortion-free, deep bass that enhances the sound experience.

How do the Thiele Small parameters affect the sound quality of the HMS 10 S2-LD-SW?

The Thiele Small parameters of the HMS 10 S2-LD-SW Subwoofer provide deeper insights into its acoustic performance. The Qts parameter of 0.60 and a high Qms of 12.3 ensure balanced damping and resonance, while the Fs value at 43 Hz indicates that the Subwoofer can efficiently reproduce low bass frequencies. These parameters determine the overall response of the speaker in its enclosure and play a significant role in facilitating adjustments for optimal sound quality, whether in quiet or dynamic heavy sound.

How important is the impedance in the HMS 10 S2-LD-SW?

The impedance of the HMS 10 S2-LD-SW is 2 Ohms, which is significant for efficiency and integration into existing systems. A low impedance results in lower electrical resistance, allowing for more power to be delivered. This feature is particularly important when high signal levels are required. Additionally, it enables easy coupling with Amplifiers that can operate at 2 Ohms. Combined with the appropriate load capacity, the full bass pressure of the Subwoofer is unleashed without overloading the amplifier or compromising sound quality.

What materials are used in the membrane of the HMS 10 S2-LD-SW?

The membrane of the HMS 10 S2-LD-SW is made of polypropylene, which is equipped with UV inhibitors. This material choice not only ensures durability and resistance to the challenges of a marine environment but also guarantees precise bass reproduction. Polypropylene allows for a sturdy yet lightweight construction, facilitating the drive of the membrane without structural compromises. Thus, you get a Subwoofer that withstands not only mechanical but also climatic stresses of marine use while providing consistent sound quality.

For which type of enclosure is the HMS 10 S2-LD-SW suitable?

The HMS 10 S2-LD-SW is specifically designed for use in sealed boxes, which helps minimize distortion and enhance fidelity. The enclosure volumes can vary between a compact version of 50 liters and a performance-optimized one of 71 liters. However, the type of box remains crucial to extract the optimal sound from the Subwoofer. With precise measurements for the boxes, the HMS 10 S2-LD-SW offers reduced resonances and enhanced bass output, which is ideal for clearly defined, powerful bass in a marine environment.

Are there any special features of the magnet in the HMS 10 S2-LD-SW?

The magnet of the HMS 10 S2-LD-SW is made from high-density flux ferrite, which allows for strong magnetic field control. The dimensions of 140 mm x 60 mm x 30 mm illustrate its performance capabilities. This design not only enables high stability during operation but also allows for precise movement of the diaphragm, which is crucial for clear and dynamic bass reproduction. The stable magnetic field reduces distortion and significantly improves sound quality, even under high power demands, as typically encountered in marine applications.

How is the load capacity of the HMS 10 S2-LD-SW affected?

The load capacity of the HMS 10 S2-LD-SW is influenced by various factors, including the voice coil, the displacement (Xmax), and the thermal capacity of the diaphragm. In particular, the adjustment of the voice coil capability at 50 mm diameter contributes to excellent heat dissipation during prolonged use. Similarly, the specified Xmax value of 12.3 mm aids in the even distribution of mechanical stress and, in conjunction with the high-quality diaphragm material, ensures consistently high performance without loss of sound details – optimal for conditions aimed at high volume and extreme bass reproduction.
