Frequent questions about Radioactive GZRW 15XSPL

Welche Leistung bietet der Radioactive GZRW 15XSPL?

The Radioactive GZRW 15XSPL from Ground Zero delivers an impressive rated power of 1200 Watts RMS and a peak power of 1800 Watts SPL. This performance allows the subwoofer to reproduce deep bass with exceptional clarity and precision. The 75 mm copper voice coil contributes to efficient power delivery and allows for high thermal capacity. Through Klippel® optimization, the subwoofer is technically refined, enabling high precision in sound reproduction, especially for music lovers seeking a deep, powerful bass experience.

Wie ist die Impedanz des Radioactive GZRW 15XSPL aufgebaut?

The Radioactive GZRW 15XSPL features a dual impedance structure of 2x 2 ohms. This dual voice coil configuration offers flexibility in installation, as it allows for various wiring options to meet the specific requirements of an audio system. For example, both coils can be connected in parallel to further reduce impedance, or in series to increase resistance, depending on the amplifier's requirements. This adaptability is particularly valuable in optimizing the overall performance of the audio system.

Welche besonderen Materialien werden im Bau des Radioactive GZRW 15XSPL verwendet?

The Radioactive GZRW 15XSPL from Ground Zero uses a reinforced paper membrane known for its lightweight yet stable construction. This membrane is crucial for clean, distortion-free bass reproduction. Additional materials include a resonance-optimized steel basket that ensures structural integrity, as well as a 2-layer polycot centering for increased durability. The use of these high-quality materials helps the subwoofer remain stable under high-performance conditions while delivering excellent sound quality.

Welche technischen Details machen den Radioactive GZRW 15XSPL besonders?

The Radioactive GZRW 15XSPL features Klippel® optimization, which enhances sound accuracy. With a long-stroke sandwich surround design, the subwoofer achieves an Xmax of 45 mm, providing particularly deep bass reproduction. It has an efficiency of 87.8 dB, meaning it delivers more sound power with less power consumption. Additionally, the 75 mm copper voice coil, along with the 2-layer polycot centering, allows for precise reproduction under maximum load.

Wie lauten die Dimensionen des Radioactive GZRW 15XSPL und wie beeinflussen sie die Installation?

With a diameter of 38 cm (15") and a mounting depth of 186 mm, the Radioactive GZRW 15XSPL is designed for most common enclosure applications. The dimensions allow for a variety of installation options, whether in sealed or bass reflex enclosures, to meet the specific requirements for sound quality. It is important to match the volume of the enclosure to the equivalent air volume (Vas) of 63.3 L to achieve the best possible performance in terms of sound depth and sound pressure.

Was sind die Klangeigenschaften des Radioactive GZRW 15XSPL?

The Radioactive GZRW 15XSPL offers an extraordinarily deep, voluminous bass foundation through its Klippel® optimization and long-stroke sandwich surround, making it ideal for music genres with a high bass content. The membrane made of reinforced paper ensures a clean bass sound without disturbing distortions. With a resonance frequency of 34.1 Hz, it is optimally suited for low-frequency reproduction and delivers an excellent damping factor (Qts) of 0.59, which means it responds dynamically and precisely to a wide range of frequencies.

Was bedeutet die Klippel®-Optimierung beim Radioactive GZRW 15XSPL?

The Klippel® optimization of the Radioactive GZRW 15XSPL refers to a technological process that ensures the component delivers optimal acoustic performance under real conditions. This process takes into account and minimizes nonlinear distortions that can occur at high volumes. By precisely monitoring the magnet and drive components, an improvement in the overall control and dynamics of the subwoofer is achieved, ultimately ensuring accurate and clean bass reproduction, even at maximum load.

Welche Vorteile bietet die Langhub-Sandwich-Sicke beim Radioactive GZRW 15XSPL?

The long-stroke sandwich surround of the Radioactive GZRW 15XSPL facilitates an exceptional excursion and thus an extended frequency range in bass reproduction. This construction ensures increased stability and flexibility, allowing the subwoofer to produce high sound pressure without losing sound fidelity. The sandwich structure allows for better handling of high-performance frequencies while minimizing distortion, resulting in a clean, deep, and full bass experience, ideal for discerning audiophiles.

Welche Merkmale machen das IMPP Dustcap des Radioactive GZRW 15XSPL einzigartig?

The IMPP dust cap of the Radioactive GZRW 15XSPL is adorned with a striking 3D logo and serves to protect the internal components while simultaneously improving mass vibration properties. The material used, Injection Molded Polypropylene (IMPP), is both lightweight and robust, meaning it minimizes vibrational energy loss, allowing the driver to operate more efficiently. This technical sophistication contributes to a clear, powerful sound image, which is particularly advantageous when reproducing low-frequency tones.

Welche Installationstipps gibt es für den Radioactive GZRW 15XSPL Subwoofer?

The installation of the Radioactive GZRW 15XSPL should take into account its installation depth of 186 mm. A suitable installation in a housing with sufficient volume, ideally adjusted to the equivalent air volume (Vas) of 63.3 L, significantly improves bass quality. Also, ensure that the housing is mounted securely to minimize resonances. In terms of wiring, the impedance of 2x 2 Ohms allows for both parallel and series connection options for flexible adaptation to your amplifier.

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!
