Frequent questions about Radioactive GZRW 300-D2 FLAT

Welche technischen Merkmale hat der Radioactive GZRW 300-D2 FLAT Subwoofer?

The Radioactive GZRW 300-D2 FLAT Subwoofer from Ground Zero offers a variety of technical features. It is a 30 cm (12") flat subwoofer with an efficient ferrite drive. The sandwich membrane made of paper, in conjunction with the durable rubber surround, ensures outstanding sound quality. The flat GZ-design steel basket, a 50 mm copper voice coil, and the aluminum dust cap not only enhance performance but also improve the visual appearance. This model is designed as a high-quality street subwoofer and has a power handling capacity of 450 watts RMS at an impedance of 2x 2 ohms.

Wie hoch ist die Belastbarkeit des Radioactive GZRW 300-D2 FLAT?

The load capacity of the Radioactive GZRW 300-D2 FLAT subwoofer from Ground Zero is 450 watts RMS. This means that the subwoofer can continuously handle this power without being damaged. In practice, you should ensure that the power recommendation is in the range of 200 to 800 watts to ensure optimal operation and to avoid overloading the subwoofer. This ensures that the sound quality remains consistently high, which is especially important for demanding audio applications. Be sure to adjust the power according to your needs.

Welche Abmessungen hat der Radioactive GZRW 300-D2 FLAT?

The Radioactive GZRW 300-D2 FLAT subwoofer has a diameter of 30 cm, which is approximately 12 inches. The installation width is 278 mm, while the installation depth is 93 mm. These compact dimensions make the subwoofer ideal for vehicles with limited space. Its flat design allows the subwoofer to be integrated into places where conventional models might not fit. When installing, ensure that there is enough space for the freedom of the voice coil and ventilation to avoid compromising sound quality.

Wie beeinflusst die Aluminium Dustcap die Leistung des Radioactive GZRW 300-D2 FLAT?

The aluminum dust cap of the Radioactive GZRW 300-D2 FLAT provides increased stability and protection for the voice coil by preventing dust and dirt from entering. This improves the durability and reliability of the subwoofer. Technically speaking, the aluminum dust cap also affects the overall mass of the membrane structure, which can positively influence the transient response characteristics. Therefore, this component contributes to clear and precise sound reproduction, which is particularly beneficial for deep bass tones. The dust cap is thus not only aesthetically pleasing but also functionally valuable.

Welche Rolle spielt die Gummisicke beim Radioactive GZRW 300-D2 FLAT?

The durable rubber surround of the Radioactive GZRW 300-D2 FLAT serves as a movable suspension for the diaphragm, allowing it to move freely without losing stability. It helps to bring the subwoofer to its maximum excursion of 30 mm, which is important for producing deep and powerful bass tones. The use of rubber provides the necessary flexibility while simultaneously reducing distortion by minimizing unwanted resonances. This technical characteristic ensures that the sound remains clear and precise even at high volumes.

Welche Parameter bestimmen die Klangqualität des Radioactive GZRW 300-D2 FLAT?

The Radioactive GZRW 300-D2 FLAT subwoofer offers various technical parameters that significantly determine sound quality. The resonance frequency (Fs) of 23.5 Hz indicates that the subwoofer can particularly emphasize deep bass. The total quality factor (Qts) is 0.44, which provides a good compromise between bass and mids. The equivalent air volume (Vas) is specified as 60.2 L, supporting the subwoofer's ability to produce deep sound in enclosed spaces. Together, these parameters provide a clear guideline on how the subwoofer should be used to achieve the best possible sound quality.

Wie beeinflusst die Kupferschwingspule die Leistung des Radioactive GZRW 300-D2 FLAT?

The 50 mm copper voice coil of the Radioactive GZRW 300-D2 FLAT is a crucial element for its performance. Copper is used due to its excellent electrical and thermal conductivity, which ensures that electrical energy is efficiently converted into mechanical movements. The size of the voice coil directly affects the load capacity and the ability of the subwoofer to continuously deliver high power. A larger voice coil, as in this model, minimizes the risk of thermal compression and increases precision at high volumes, resulting in the subwoofer producing excellent sound dynamics.

Wie ist der Wirkungsgrad des Radioactive GZRW 300-D2 FLAT Subwoofers?

The efficiency of the Radioactive GZRW 300-D2 FLAT is 85 dB. This means that the subwoofer can produce a sound pressure level of 85 dB with one watt of input power. A higher efficiency indicates a speaker's ability to achieve more volume with less energy. In practice, this means that attention is paid to efficient power usage while maintaining consistent sound quality. This is particularly important in car audio systems, where efficiency has a direct impact on overall system performance and energy consumption. Thus, this subwoofer is perfect for energy-efficient installations.

Wie passt der Radioactive GZRW 300-D2 FLAT in ein Auto?

The Radioactive GZRW 300-D2 FLAT can be easily integrated into many vehicle interiors thanks to its compact installation dimensions of 278 mm and a depth of 93 mm. Its flat design allows it to be installed in places where conventional subwoofers may not fit, such as under seats or in tight trunk sections. If you need installation tips, it is advisable to accurately measure the available space in your car to ensure that the subwoofer fits properly and can operate the desired sound without structural or acoustic impairments.

Welche Installationshinweise gibt es für den Radioactive GZRW 300-D2 FLAT?

When installing the Radioactive GZRW 300-D2 FLAT subwoofer, several steps should be considered. Due to the installation diameter of 278 mm and a depth of 93 mm, it is suitable for tight spaces. It is important to ensure that the installation area is free of obstacles that could obstruct the voice coil before mounting. The subwoofer should also be securely fixed to minimize unwanted vibrations and maintain sound fidelity. Checking all connections for safety and stability helps ensure long-lasting and trouble-free functionality.

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!
