Frequent questions about Radioactive GZRB 16SPL

Wie hoch ist die Belastbarkeit des Radioactive GZRB 16SPL?

The Radioactive GZRB 16SPL from Ground Zero offers an impressive maximum load capacity of 700 watts, making it ideal for powerful bass and high-performance sound. The RMS load capacity is 300 watts, allowing for continuous power consumption during prolonged use. Such a high load capacity ensures that the subwoofer performs well even with demanding music genres and high volumes without sound distortion. It is crucial to consider these wattage figures when using an amplifier to avoid sound distortions. Technologies like this ensure you a rich bass experience.

Welche Abmessungen hat das Gehäuse des Radioactive GZRB 16SPL Subwoofers?

The housing of the Ground Zero Radioactive GZRB 16SPL measures 410 x 280 x 130 mm. These compact dimensions facilitate installation in the vehicle, especially in areas with limited space such as the trunk. The net volume remains at 8.5 liters, which is crucial for optimal sound frequency response. With this size, thoughtful placement is essential. Ensure there is sufficient space for air circulation to challenge the bass reflex. When used in the car, precise measurement of the installation space is important to optimally position the subwoofer.

Welche Impedanz bietet der GZRB 16SPL und was bedeutet das für die Installation?

The Radioactive GZRB 16SPL is equipped with an impedance of 2x 2 ohms. The dual impedance allows for versatile configurations in your audio system, such as parallel or series wiring. This flexibility is particularly advantageous for tuning with the amplifier, as it can be used differently depending on the design. The low ohm value allows for higher power flow, which is beneficial for bass pressure. When installing, you should ensure that the amplifier is compatible with this impedance for an optimal sound experience.

Für welchen Subwoofer-Typ ist der Radioactive GZRB 16SPL ausgelegt?

The Radioactive GZRB 16SPL from Ground Zero is a so-called SPL enclosure subwoofer model that has been optimized for Sound Pressure Level. This means that the subwoofer is designed to produce high sound pressure levels, providing intense bass that you can use for outdoor sound systems as well as in your vehicle. With its SPL design combined with a bass tunnel, it creates a deep and clear bass experience, ideal for anyone who prefers music with particularly powerful bass.

Welche Rolle spielt das Bassreflexgehäuse beim GZRB 16SPL?

The bass reflex enclosure of the Radioactive GZRB 16SPL from Ground Zero is crucial for expanding frequency reproduction. It utilizes airflow to represent low frequencies more efficiently by using a bass tunnel to optimize the airflow. This construction significantly affects sound quality and bass volume, numerically influencing the acoustic volume. This is particularly important for pressure equalization and sound precision, further intensifying the listening experience. A well-constructed bass reflex enclosure thus ensures more impressive, dynamic bass.

Welche Vorteile bietet der Holzbau des Radioactive GZRB 16SPL-Gehäuses?

The housing of the Radioactive GZRB 16SPL from Ground Zero is made of robust wood, which offers several tonal advantages. Wood as a material has beneficial properties regarding damping and resonance, which are important for the reproduction of clean low-frequency sounds. While plastic often tends to produce a 'booming' effect, wood remains acoustically neutral, leading to a pure and authentic sound. The solid construction from wood also increases stability, which is essential at higher volumes to minimize unwanted vibrations and distortion noises. The craftsmanship significantly contributes to the longevity of the system.

Was bedeutet die Klemm-Verbindung beim GZRB 16SPL?

The clamp connection on the Radioactive GZRB 16SPL from Ground Zero allows for a secure and reliable connection to your audio system. By using this connection method, a firm and lossless contact between the subwoofer and the cables is ensured. This reduces resistance as well as the loss of electrical signal transmission, thereby improving the overall performance of your audio setup. The simple installation particularly supports those users who frequently rearrange or expand their sound equipment. The possibility of an easy connection promotes maximum signal purity for an outstanding musical experience.

Wie wird der Subwoofer GZRW 6XSPL im Radioactive GZRB 16SPL genutzt?

In the Radioactive GZRB 16SPL, the subwoofer GZRW 6XSPL serves as the central element for powerful bass reproduction. This 16.5 cm subwoofer is specifically designed for high loads, fits seamlessly into the bass reflex enclosure, and harmonizes ideally with the bass tunnel to produce a punchy sound. Its construction and load capacity ensure that it delivers strong, deep tones with minimal distortion. Whether for rock, hip-hop, or electronic music, the GZRW 6XSPL supports voluminous and dynamic bass reproduction, fulfilling the desires of bass enthusiasts.

Welche Frequenzbereiche werden durch den Radioactive GZRB 16SPL abgedeckt?

The Radioactive GZRB 16SPL from Ground Zero has been specifically designed to reproduce deep frequency ranges without resonance, ideal for an acoustic that is penetrating and voluminous. The bass reflex enclosure helps to amplify the lowest frequencies and enables precise bass reproduction optimized for SPL applications. The subwoofer is designed to distribute sound waves losslessly in the room, ensuring that even critical frequencies in the bass segment are fully realized. This bass depth significantly contributes to enriching every piece of music with its full leakage and power.

Welche Tipps gibt es zur Installation des Radioactive GZRB 16SPL?

For the installation of the Radioactive GZRB 16SPL in the vehicle, it is crucial to consider the dimensions of 410 x 280 x 130 mm and ensure that there is enough space available. Particularly, the placement in the trunk can affect the acoustic effect; therefore, make sure that the subwoofer is not blocked by other objects. Additionally, the clamp connection with the input cables should be securely connected to avoid compromising sound quality. The use of suitable seals also prevents unwanted vibrations, while the correct alignment of the bass reflex opening of the noise level can be crucial.

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!
