Frequent questions about Radioactive GZRW 12XSPL

Welche Leistungsdaten hat der Ground Zero Radioactive GZRW 12XSPL?

The Ground Zero Radioactive GZRW 12XSPL subwoofer impresses with its remarkable load capacity of 1000 watts RMS and 1500 watts peak power. With a resonance frequency of 31.8 Hz, it delivers strong bass reproduction. The efficiency is at 83 dB, ensuring a powerful sound. The voice coil measures a generous 75 mm and allows for a maximum excursion of 45 mm, which brings out the deep frequencies significantly. This makes the subwoofer ideal for music genres with deep bass such as hip-hop or electronic music.

Wie ist die Papiermembran des Radioactive GZRW 12XSPL ausgelegt?

The Ground Zero Radioactive GZRW 12XSPL is equipped with a fiber-reinforced paper diaphragm. This special construction provides an optimal mix of stiffness and lightweight, allowing the subwoofer to reproduce precise and powerful bass impulses. The reinforced diaphragm supports the durability and robustness of the subwoofer by resisting vibrations that can occur at high volumes. These technical features ensure high audio quality, especially when dynamic and distortion-free sound reproduction is crucial.

Welche Rolle spielt die Klippel® Optimierung beim Radioactive GZRW 12XSPL?

The Radioactive GZRW 12XSPL subwoofer from Ground Zero benefits from Klippel® optimization, which allows for precise analysis and improvement of speaker parameters through state-of-the-art measurement methods. This optimization ensures that the subwoofer operates linearly and with low distortion across the entire frequency range. Klippel® technology primarily optimizes the moving assembly consisting of the voice coil, diaphragm, and centering to ensure maximum displacement without sound loss and to enhance overall sound quality, which is particularly relevant in SPL scenarios.

Wie beeinflusst die 75 mm Kupferschwingspule den Klang des GZRW 12XSPL?

The 75 mm copper voice coil in the Ground Zero Radioactive GZRW 12XSPL is crucial for the performance of the subwoofer. A larger voice coil provides increased load capacity and more efficient heat dissipation, ensuring consistent performance during prolonged and loud sessions. Copper as a material also guarantees excellent conductivity, which helps convert the electromagnetic movements into precise mechanical movements of the diaphragm, resulting in a clearer sound image. These specifications make it ideal for high-performance music systems.

Welche Abmessungen hat der Radioactive GZRW 12XSPL und wie installiere ich ihn?

The Ground Zero Radioactive GZRW 12XSPL has a mounting diameter of 288 mm and a mounting depth of 166 mm. These are crucial dimensions for preparing the installation in a housing. It is important to ensure adequate air circulation around the subwoofer to efficiently dissipate heat. For installation, it is recommended to optimally utilize the available trunk space so that the maximum excursion of the diaphragm is not obstructed. The exact installation position depends on the individual vehicle design and the desired orientation for acoustic benefits.

Welche Impedanz hat der GZRW 12XSPL und wie wirkt sie sich aus?

The Radioactive GZRW 12XSPL features a dual impedance of 2x 2 ohms. This configuration allows for flexible adaptation to various amplifier systems to achieve the best performance. Operating in 1-ohm mode enables maximum power output from the amplifier, while the 4-ohm configuration promotes more efficient power usage and less heat generation. The flexibility in impedance makes this subwoofer versatile and allows it to be seamlessly integrated into different high-end audio setups, depending on individual sound requirements.

Welche Materialien sind im resonanzarmen Stahlkorb des GZRW 12XSPL verwendet?

The Ground Zero Radioactive GZRW 12XSPL uses a resonance-optimized steel basket that has been specifically designed to minimize unwanted vibrations and resonances that could lead to sound distortions. The steel provides a highly stable structure and additionally supports the proper alignment and durability of the subwoofer's moving parts. This construction enhances the lifespan and reliability of the subwoofer, especially under intense use in SPL applications. This aspect is particularly relevant in applications that require maximum performance.

Wie trägt die Langhub-Sandwich-Einfassung zur Leistung des GZRW 12XSPL bei?

The long-stroke sandwich surround of the Ground Zero Radioactive GZRW 12XSPL allows for particularly high membrane excursion, which is crucial for deep bass. This surround ensures that the membrane operates in a controlled manner by providing stability and flexibility in movement. It minimizes distortion and ensures precise reproduction even at high volumes. In practice, this means that you can expect consistent sound quality, even during intense musical passages, which is particularly critical for SPL applications.

Welche Rolle spielt die 2-Schicht-Polycot-Zentrierung im GZRW 12XSPL?

In the Ground Zero Radioactive GZRW 12XSPL, the 2-layer polycotton centering ensures precise and stable guidance of the voice coil. This centering technology guarantees uniform movement and minimizes mechanical friction. As a result, there is increased efficiency and lasting sound quality, as unwanted displacements of the voice coil are avoided. Especially at high volumes and extreme temperatures, the performance of the subwoofer remains constant. This is particularly important for music genres that require intense bass, as it keeps distortion to a minimum.

Welchen Einfluss hat die IMPP-Staubschutzkappe im Radioactive GZRW 12XSPL?

The IMPP dust protection cap with 3D logo on the Ground Zero Radioactive GZRW 12XSPL protects the internal structure of the subwoofer from dust and other contaminating particles. This is crucial for maintaining sound definition and the lifespan of the moving parts. The cap also supports the mechanical integrity of the subwoofer by providing additional stability. Noise generation due to dust accumulation is significantly reduced. This technical solution not only improves reliability but also advances with a stylish design that is visually appealing.

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!
