Frequent questions about Hydrogen GZHW 38XSPL


Was sind die technischen Spezifikationen des Hydrogen GZHW 38XSPL Subwoofers?

The Hydrogen GZHW 38XSPL from Ground Zero is a 15-inch SPL subwoofer. It offers an RMS power of 1500 watts and a peak power handling of 3500 watts. With an impedance configuration of 2x 1 ohm or 2x 2 ohm, it is versatile and adaptable. The efficiency is at 87 dB, which indicates efficient performance. Equipped with a 75 mm copper voice coil and a massive aluminum die-cast basket, it provides impressive sound fidelity. The resonance frequency is 36.3 Hz, and the subwoofer can achieve a maximum excursion of 45 mm. Cutout diameter: 360 mm.

Wie passt der Hydrogen GZHW 38XSPL Subwoofer in mein Auto?

The Hydrogen GZHW 38XSPL has a mounting diameter of 360 mm and a resonance frequency of 36.3 Hz, making it compatible with most standard subwoofer enclosures. When installing, it is important to leave enough space for the long-stroke sandwich surround to achieve optimal sound quality. Depending on the vehicle model, the massive 15-inch subwoofer may require more space. For proper adaptation to the onboard network, the impedance configuration of 2x 1 Ohm or 2x 2 Ohm offers flexibility. Technical adjustments should be made professionally to avoid complications with sound pressure distribution.

Was ist die Funktion der Kupferschwingspule im Hydrogen GZHW 38XSPL?

The 75 mm copper voice coil of the Hydrogen GZHW 38XSPL subwoofer ensures excellent heat resistance and allows for a high load capacity of up to 3500 watts. Especially in intense SPL applications, the sound performance remains stable without thermal issues. Copper offers excellent electrical conductivity, minimizing losses and maintaining an efficiency of 87 dB. The voice coil is optimally tuned with the reinforced paper cone and the long-stroke sandwich surround, ensuring clear low-frequency reproduction. The efficient heat dissipation supports the copper voice coil in high-power demands.

Welche Rolle spielt die Langhub-Sandwich-Sicke beim SPL Subwoofer?

The long-stroke sandwich surround of the Hydrogen GZHW 38XSPL is crucial for large displacements, up to a maximum of 45 mm. This design allows the subwoofer to produce clean and distortion-free bass at high volumes. The sandwich construction ensures stability and durability, even with intense use. It ensures that the vibrations are optimally transferred to the reinforced paper diaphragm without causing sound distortions. This keeps the sound precise even at maximum volume. The design of the surround minimizes mechanical resistance.

Wie wird die verstärkte Papiermembran des Subwoofers optimiert?

The reinforced paper diaphragm of the Hydrogen GZHW 38XSPL, complemented by Klippel® optimization, offers significantly improved sound radiation. This optimization reduces unwanted cone movements under high load, allowing the subwoofer to deliver precise and clean bass tones. The paper diaphragm provides the ideal mix of lightness and strength, enabling quick response and minimal energy loss. At a maximum output of 3500 watts, the diaphragm remains robust without structural compromises. This design supports the accurate reproduction of low frequencies and ensures impressive bass performance.

Was ist die IMPP Dustcap mit 3D Logo beim Ground Zero Subwoofer?

The IMPP dustcap with 3D logo on the Hydrogen GZHW 38XSPL serves both an aesthetic and a functional role. The structured surface enhances the mechanical grip of the central membrane layer by reducing resonances that could affect sound quality. IMPP as a material is characterized by its resistance to environmental influences and preserves its acoustic properties over a long time. The 3D logo gives the subwoofer a distinctive, modern look that highlights the design of the vehicle's interior. A stable dustcap is crucial for maintaining structural integrity at high volumes.

Warum ist der Aluminium-Gusskorb für den Subwoofer relevant?

The massive aluminum cast basket of the Hydrogen GZHW 38XSPL provides essential stability and durability. Aluminum is a lightweight material that, despite its low mass, has high structural strength, which is important for sound transmission. The cast basket protects internal components such as the copper voice coil and the centering system from mechanical shocks. A stable housing structure minimizes resonances that could affect the sound and, together with the reinforced paper diaphragm, contributes to the reproduction of clear and distortion-free bass. Even during prolonged use at high levels, the subwoofer remains stable.

Was bringt die zweilagige Polycot Zentrierung dem Subwoofer?

The two-layer Polycot centering of the Hydrogen GZHW 38XSPL ensures that the membrane remains precisely centered even at large deflections. By combining two layers of Polycot, a special fabric, the balance between flexibility and shape retention is achieved, which is crucial for precise movements. This reduces mechanical distortions and ensures that sound production remains consistent under high load. The choice of Polycot material supports temperature resistance and achieves optimal damping of unwanted vibrations. These properties make the centering highly effective in SPL applications.

Welche Vorteile bietet die Klippel® Optimierung für Ground Zero Subwoofer?

The Klippel® optimization of the Hydrogen GZHW 38XSPL ensures precise and efficient sound reproduction by specifically reducing unwanted mechanical and thermal distortions. The process optimizes the performance of the subwoofer through exact analyses of magnetic field and voice coil properties. This optimization is particularly important under high power demands, as it minimizes asymmetric movements, thus ensuring consistent sound quality. Especially in the SPL range, the Hydrogen subwoofer benefits from this technology, as it increases mechanical linearity and maximizes load capacity.

Welche Leistungsempfehlung gibt es für den Hydrogen GZHW 38XSPL?

The power recommendation for the Hydrogen GZHW 38XSPL subwoofer ranges from 1500 to 3500 watts, allowing for flexible adaptation to various amplifier setups. This range ensures that the subwoofer can deliver its optimal sound quality in different applications, from everyday use to SPL competitions. Within this power range, SPL values can be achieved that far exceed conventional systems. An important parameter is the impedance of either 2x 1 ohm or 2x 2 ohm, which ensures precise tuning to existing amplifier concepts and efficient power transfer.
