Frequently Asked Questions about Hydrogen GZHW 20XSPL

What is the power of the Hydrogen GZHW 20XSPL Subwoofer?

The Hydrogen GZHW 20XSPL Subwoofer from Ground Zero offers an impressive RMS power of 700 watts and a maximum SPL power of 1500 watts. The recommended power range for this subwoofer is between 300 and 1500 watts, allowing for flexible adaptation to different amplifier outputs. The subwoofer is designed to be suitable for both moderate and demanding audio applications without compromising sound quality. The high-quality 63 mm copper voice coil ensures stable performance over a wide range.

How does the Klippel® optimization affect the Ground Zero Hydrogen GZHW 20XSPL?

The Klippel® optimization in the Hydrogen GZHW 20XSPL Subwoofer provides precise control and analysis of the mechanical and electromagnetic properties of the speaker. This leads to improved sound quality and performance by minimizing distortion and maximizing the linearity of the motion. Additional optimizations include the adjustment of the long-stroke sandwich surround and the reinforced paper cone to ensure stable and clear bass frequencies, even at high volumes.

Does the Ground Zero Hydrogen GZHW 20XSPL Subwoofer fit in my car?

To install the Ground Zero Hydrogen GZHW 20XSPL in your vehicle, the installation dimensions should be considered. The required installation diameter is 187 mm and the installation depth is 145 mm. The design of the solid aluminum die-cast basket allows for a stable and secure installation. Due to the available impedances of 2x 1 ohm or 2x 2 ohm, various wiring options can be utilized to optimally adapt the subwoofer according to the conditions and amplifier requirements. The impressive Xmax of 40 mm ensures effective bass reflections.

What impedance options does the Hydrogen GZHW 20XSPL Subwoofer offer?

The Hydrogen GZHW 20XSPL from Ground Zero is available in two different impedance configurations: 2x 1 Ohm or 2x 2 Ohm. This allows for flexible adaptation to various amplifier and power configurations. Choosing the right impedance is crucial to extract maximum performance from your sound system while optimizing the thermal load of the amplifier. The dual voice coil configuration also allows for a variety of wiring options to achieve the desired sound character.

What distinguishes the diaphragm of the Ground Zero Hydrogen GZHW 20XSPL?

The diaphragm of the Hydrogen GZHW 20XSPL Subwoofer is made of reinforced paper, making it particularly robust and resonance-free. This design supports the generation of deep, rich bass and enhances overall acoustics. The long-stroke sandwich surround complements the diaphragm with its flexibility and stability, allowing for more linear movements and lower distortion even at high output levels. The system is equipped with an IMPP dust cap featuring a 3D logo, providing additional protection and aesthetic value.

How is the sound quality of the Hydrogen GZHW 20XSPL maximized?

The sound quality of the Ground Zero Hydrogen GZHW 20XSPL is maximized through a combination of technical features. The 63 mm copper voice coil offers high thermal resilience and reduces distortion. The efficiency of 80 dB enables effective energy conversion into sound. The resonance frequency of 38.3 Hz produces a deep and precise bass foundation. The total quality factor (Qts) of 0.381 shows a good balance between bandwidth and efficiency, while the equivalent volume (Vas) of 4.77 L provides perfect resonator characteristics.

What is the maximum displacement of the Ground Zero Hydrogen GZHW 20XSPL?

The Ground Zero Hydrogen GZHW 20XSPL Subwoofer has a maximum displacement, also known as Xmax, of an impressive 40 mm. This high displacement allows for more drastic movements of the diaphragm, resulting in more intense bass reproduction. The construction with the long-stroke sandwich surround supports this displacement by ensuring flexibility and stability. This is particularly important for listeners who prefer deep and powerful bass sounds, ensuring that even at high volumes, the signal processing remains perfect.

What advantages does the aluminum die-cast basket offer in the GZHW 20XSPL?

The massive aluminum die-cast basket of the Ground Zero Hydrogen GZHW 20XSPL offers numerous advantages. It provides a highly stable structure that minimizes vibrations, thereby improving sound quality. Aluminum offers excellent thermal conductivity properties, effectively dissipating thermal stress during operation. This robust construction also contributes to increased durability of the Subwoofer, ensuring consistent performance over longer periods. It is an ideal design for precise bass management and high sound pressure.

What is the significance of the Polycot centering in the Hydrogen GZHW 20XSPL?

The two-layer Polycot centering of the Hydrogen GZHW 20XSPL is crucial for the precise alignment and stability of the voice coil during operation. This structure prevents lateral movements that could lead to distortion and ensures uniform and interference-free displacement of the diaphragm. This guarantees outstanding precision in bass reproduction, as the voice coil is guided accurately even with dynamic changes in audio signals. This feature is particularly advantageous for demanding audio applications.

How does the efficiency of 80 dB affect the Subwoofer?

The efficiency of 80 dB of the Ground Zero Hydrogen GZHW 20XSPL Subwoofer indicates how efficiently the speaker converts electrical energy into acoustic energy. An efficiency of 80 dB is remarkable, as it achieves clear and powerful reproduction even at low power. For users, this means that less power is required from the Amplifier to operate the Subwoofer at adequate volumes, keeping energy consumption moderate. This balance of efficiency and sound intensity makes it particularly suitable for various sound systems.

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.
