Frequently Asked Questions about Hydrogen GZHW 38

What power does the GZHW 38 Subwoofer offer?

The GZHW 38 from Ground Zero impresses with its maximum load capacity of 3500 Watts SPL, combined with an RMS power of 1500 Watts. It utilizes a Klippel®-optimized design to achieve excellent performance in volume and clarity. Its aluminum die-cast basket and 75 mm copper voice coil contribute to its robustness, while the reinforced paper cone ensures sound precision. This Subwoofer is designed for strong bass, with an efficiency of 87 dB, allowing it to operate without distortion even at high volumes. Ideal for intense audio experiences at high power.

How is the impedance of the GZHW 38 configured?

The GZHW 38 from Ground Zero offers two options for impedance configuration, either 2x1 Ohm or 2x2 Ohm, to ensure flexibility when used in different audio systems. This dual impedance allows you to configure the Subwoofer according to your amplifier to achieve either higher power or greater stability. The 75 mm copper voice coil helps minimize losses and efficiently dissipate heat, ensuring consistent sound quality even under heavy load. This versatility makes it an ideal choice for custom car audio setups.

What dimensions are important for installing the GZHW 38?

When installing the GZHW 38, the space in the vehicle or speaker box is crucial. It has a diameter of 38 cm and requires a cutout diameter of 360 mm. The mounting depth is 231 mm, which must be taken into account during planning. The maximum excursion of 45 mm should also be considered to ensure smooth operation. With these dimensions, it is important that the Subwoofer has enough space for air circulation and cooling and does not interfere with other components. Placement and precise measurement control are essential for optimal performance.

How does the resonance frequency affect the sound of the GZHW 38?

The resonance frequency of the GZHW 38 is 36.3 Hz, a crucial parameter for deep bass reproduction. This frequency indicates at which oscillation frequency the Subwoofer operates most efficiently, especially for reproducing low bass notes. A low resonance frequency is ideal for representing deep sound frequencies, making the GZHW 38 the perfect choice for audio enthusiasts who desire powerful and immersive bass lines in their audio setup. Thanks to the optimal resonance frequency, the Subwoofer is excellent for genres like Hip-Hop or Electronic Dance Music, which benefit from strong bass.

What are the advantages of the reinforced paper diaphragm in the GZHW 38?

The reinforced paper diaphragm of the GZHW 38 Subwoofer offers a combination of lightness and stiffness, which significantly contributes to sound quality. This diaphragm structure ensures clear, precise bass reproduction and minimizes distortion at high volumes. Paper provides a natural sound due to its damping properties and is appreciated by many audio experts for its superior sound quality compared to synthetic materials. The reinforcement increases durability and robustness, which, combined with the aluminum casting technique of the basket, results in a long-lasting and high-performance Subwoofer.

What role does the voice coil play in the GZHW 38?

The voice coil of the GZHW 38 has a diameter of 75 mm and is made of high-quality copper. This large copper voice coil allows for excellent performance under high load and significantly contributes to heat dissipation, preventing thermal damage and increasing the longevity of the Subwoofer. Due to its resilient construction, it enables precise control of diaphragm movement, resulting in clear, powerful sound. Especially during long listening sessions at high volume, the voice coil is crucial to protect the Subwoofer from overheating and distortion.

What influence does the overall quality of the GZHW 38 have on bass reproduction?

With an overall quality (Qts) of 0.52, the GZHW 38 is designed for balanced bass reproduction. A Qts value in this range indicates the ability to perform well in both sealed and vented enclosures. This parameter describes how well the speaker is internally damped and significantly influences the sound characteristic. A Subwoofer with a medium Qts value typically offers a good mix of tight, precise bass and sufficient volume. Thus, the GZHW 38 is ideal for audio setups that demand both detail accuracy and impressive sound pressure.

How does the Klippel® technology optimize the performance of the Subwoofer?

The Klippel® technology used in the GZHW 38 optimizes the drive mechanism of the Subwoofer by precisely measuring and correcting parameters for nonlinearities in the magnet and suspension parts. This increases overall performance by reducing distortion at high volumes and improving the sound image and frequency response. This leads to accurate bass reproduction even under greater excursion and load. The Klippel® optimization significantly contributes to ensuring that the GZHW 38 remains powerful even under extreme conditions and guarantees an uncolored sound.

How do I optimally position the GZHW 38 in the car?

For optimal positioning of the GZHW 38 in the car, you need to consider the acoustic properties and specific dimensions of the Subwoofer along with the vehicle space. The installation diameter of 360 mm and the installation depth of 231 mm require sufficient space to securely mount the Subwoofer while allowing enough room for the diaphragm's excursion. Ideally, you choose a position that effectively directs the bass waves into the interior, often in the trunk or under seats. This setup maximizes sound pressure and ensures an intense listening experience with proper enclosure calculation.

What material properties ensure the stability of the GZHW 38?

The GZHW 38 is designed for stability and durability, thanks to a combination of high-quality materials. A massive aluminum die-cast basket provides a robust foundation that minimizes vibrations and maintains structural integrity. Together with the reinforced paper diaphragm and the carbon dust cap, diaphragm movement is controlled and unwanted resonances are reduced. The 75 mm copper voice coil contributes to durability under high load through excellent heat conduction. This choice of materials ensures that the Subwoofer delivers reliable performance even under extreme conditions without compromising sound quality.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
