Frequently Asked Questions about Radioactive GZRW 38-D2


What are the performance specifications of the Radioactive GZRW 38-D2 Subwoofer?

The Radioactive GZRW 38-D2 from Ground Zero offers an RMS power handling of 1000 watts and a recommended power range between 800 and 1400 watts. The efficiency is 85.8 dB. Thanks to its 75 mm copper voice coil, it can handle high volumes, while its maximum excursion (Xmax) of 50 mm ensures powerful and precise bass reproduction. The dual impedance of 2x 2 ohms allows for flexible wiring options, which is advantageous for installation in various audio systems.

What distinguishes the diaphragm of the Radioactive GZRW 38-D2?

The Radioactive GZRW 38-D2 is equipped with a reinforced paper diaphragm. This design combines lightweight with high stability, contributing to a clear and precise sound image. Particularly noteworthy is the long-stroke sandwich surround, which optimizes diaphragm movement to produce strong and controlled bass. Due to these materials and construction, the subwoofer is ideal for use in car audio systems that focus on both sound quality and volume.

Why is Klippel optimization important for the Radioactive GZRW 38-D2?

Klippel optimization enhances the audio performance of the Radioactive GZRW 38-D2 by minimizing distortion and optimizing overall frequency response. This fine-tuning ensures that the entire audio output of the subwoofer is particularly linear and precise, reflecting in a clear and dynamic sound image. Audiophiles seeking authentic sound especially benefit from the advantages of this advanced technology. Klippel optimization significantly improves resolution and sound realism.

What materials are used in the Radioactive GZRW 38-D2?

When building the Radioactive GZRW 38-D2, Ground Zero relies on a combination of high-quality materials. The reinforced paper membrane provides excellent sound reproduction and is supported by the long-stroke sandwich surround made from a robust material mix. The Subwoofer also features a polycot center that ensures the precise alignment of the moving parts. The resonance-optimized steel basket, along with the 75 mm copper voice coil, ensures minimal distortion and enhanced sound fidelity, paired with a distinctive appearance thanks to the IMPP dust cap.

What is the compatibility of the Radioactive GZRW 38-D2 with various audio systems?

With a mounting diameter of 359 mm and a mounting depth of 195 mm, the Radioactive GZRW 38-D2 can be easily integrated into many car audio systems. Particularly important is the dual impedance of 2x 2 ohms, which allows for flexible wiring options to be compatible with various amplifiers. The resonance frequency of 22.9 Hz ensures deep bass reproduction that unfolds optimally in most sound environments.

What features does the steel basket of the Radioactive GZRW 38-D2 offer?

The Radioactive GZRW 38-D2 from Ground Zero features a specially designed, resonance-optimized steel basket. This provides a durable and stable enclosure structure that minimizes vibrations and unwanted resonances. As a result, sound quality is significantly improved by ensuring that all audio signals are reproduced without disturbing background vibrations. The construction also supports the longevity of the Subwoofer by maintaining structural integrity over extended periods.

What role does the voice coil play in the Radioactive GZRW 38-D2?

The 75 mm copper voice coil in the Radioactive GZRW 38-D2 is central to the power and sound quality of the Subwoofer. Copper as a material offers excellent electrical conductivity, leading to efficient signal transmission and minimal power loss. This ensures consistent and powerful bass reproduction, especially at high volumes. Additionally, the large coil size allows for increased heat dissipation, enhancing the thermal resilience and thus the longevity of the Subwoofer.

What is the resonance frequency of the Radioactive GZRW 38-D2 and what does it mean?

The Radioactive GZRW 38-D2 has a resonance frequency (Fs) of 22.9 Hz. This low Fs means that the Subwoofer is effective at very low frequencies and delivers impressively deep bass. Especially in applications that require powerful low-frequency response, such as home theater or car audio systems, this feature ensures that the Subwoofer produces full and room-filling bass. The resonance frequency is an important indicator of bass performance and influences the overall sound.

How is the centering of the Radioactive GZRW 38-D2 designed?

The Radioactive GZRW 38-D2 uses a polycot centering that allows for precise movement of the diaphragm. This centering ensures that the moving part of the Subwoofer remains stable and oscillates evenly during operation. This reduces distortion and improves the fidelity of sound reproduction. The polycot materials provide the optimal balance between flexibility and stability, which is particularly important at high power levels when the diaphragm needs to achieve large displacements.

What are the dimensions of the Radioactive GZRW 38-D2 and how do they affect installation?

With a diameter of 38 cm, the Radioactive GZRW 38-D2 is one of the larger Subwoofers and has a cutout diameter of 359 mm and a mounting depth of 195 mm. These dimensions are relevant for installation as they determine the required space in areas such as the trunk or specialized Subwoofer enclosures. Sufficient installation volume is important to fully utilize the Subwoofer's performance. Careful planning of the installation location is crucial for optimal acoustics and space utilization in your audio setup.
