Frequent questions about Radioactive GZRW 38-D2

Welche Leistungsdaten hat der 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 at 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 when installing in various audio systems.

Was zeichnet die Membran des Radioactive GZRW 38-D2 aus?

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 powerful and controlled bass. Due to these materials and construction, the subwoofer is ideally suited for use in car audio systems that focus on both sound quality and volume.

Warum ist die Klippel-Optimierung beim Radioactive GZRW 38-D2 wichtig?

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

Welche Materialien werden beim Radioactive GZRW 38-D2 eingesetzt?

In the construction of 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, which consists of a robust material mix. The subwoofer also features a polycot centering 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, combined with a distinctive appearance thanks to the IMPP dust cap.

Wie ist die Kompatibilität des Radioactive GZRW 38-D2 mit verschiedenen Audio-Systemen?

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.

Welche Besonderheiten bietet der Stahlkorb des Radioactive GZRW 38-D2?

The Radioactive GZRW 38-D2 from Ground Zero features a specially designed, resonance-free steel basket. This ensures a durable and stable housing 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 longer periods.

Welche Rolle spielt die Schwingspule beim 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 a consistent and powerful bass reproduction, especially at high volumes. Additionally, the large coil size allows for increased heat dissipation, which enhances the thermal resilience and thus the longevity of the subwoofer.

Welche Resonanzfrequenz hat der Radioactive GZRW 38-D2 und was bedeutet das?

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 in home theater or car audio systems, this characteristic ensures that the subwoofer produces a full and room-filling bass. The resonance frequency is an important indicator of bass performance and influences the overall sound.

Wie gestaltet sich die Zentrierung beim Radioactive GZRW 38-D2?

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.

Welche Abmessungen hat der Radioactive GZRW 38-D2 und wie beeinflussen diese die Installation?

With a diameter of 38 cm, the Radioactive GZRW 38-D2 is one of the larger subwoofers and comes with a mounting 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 special 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.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
