Frequent questions about Radioactive GZRW 250-D2 FLAT

Wie viel Leistung verträgt der Radioactive GZRW 250-D2 FLAT Subwoofer?

The Radioactive GZRW 250-D2 FLAT from Ground Zero is designed for a maximum load capacity of 400 Watts RMS. This load capacity allows the subwoofer to produce powerful bass with minimal distortion, while the recommended power consumption is in the range of 200 to 800 Watts. This power range offers flexibility in choosing the amplifier to achieve the best possible sound. Be sure to stay within the specified power recommendations to ensure the longevity and optimal function of the subwoofer without the risk of permanent damage.

Welche Abmessungen hat der Radioactive GZRW 250-D2 FLAT?

The subwoofer Radioactive GZRW 250-D2 FLAT has a diameter of 25 cm and is specifically designed with a flat design to facilitate installation in various vehicle types. The installation depth is only 85 mm and the installation diameter is 232 mm. These compact dimensions allow for easy integration into existing audio systems, especially in vehicles with limited space. The minimalist enclosure design takes into account various installation options without compromising sound quality.

Welche Materialien wurden für die Membran des Radioactive GZRW 250-D2 FLAT genutzt?

The Radioactive GZRW 250-D2 FLAT subwoofer uses a sandwich membrane made of paper. This special construction contributes to weight reduction while providing an optimal structure for vibration damping. In combination with the durable rubber surround, this results in excellent reproduction quality of low frequencies. Sandwich membranes are known for ensuring a perfect balance between stability and flexibility, which is crucial for the high performance and remarkable sound precision of the subwoofer.

Welche Resonanzfrequenz hat der Radioactive GZRW 250-D2 FLAT?

The resonance frequency of the Radioactive GZRW 250-D2 FLAT from Ground Zero is 28 Hz. This low resonance frequency is optimal for reproducing deep bass sounds and ensures that the subwoofer delivers clear and undistorted tones. Such a resonance frequency guarantees that the subwoofer provides perfect performance, especially in the area of bass reflex applications, by combining the speaker's own resonance with that of the enclosure. It results in powerful reproduction of low frequencies.

Welche Impedanz hat der Radioactive GZRW 250-D2 FLAT Subwoofer?

The Radioactive GZRW 250-D2 FLAT features a dual impedance of 2 ohms. This dual impedance configuration allows for greater flexibility in the audio system by simplifying the connection to various amplifier designs. This characteristic is excellent for complex wiring, as found in high-quality car audio systems. The dual impedance allows the subwoofer to be connected in parallel or in series, enabling flexible adjustment of the overall impedance of the system and allowing the user to customize the sound output.

Welche Thiele-Small-Parameter hat der Radioactive GZRW 250-D2 FLAT?

The Thiele-Small parameters of the Radioactive GZRW 250-D2 FLAT are crucial for calculating the optimal enclosure volume. The total quality factor (Qts) is 0.54, indicating a balanced combination between bass reflex and sealed enclosure applications. The equivalent air volume (Vas) is 35.8 L, which is used to determine the enclosure size for maximum bass output. These parameters help design the speaker enclosure so that the subwoofer performs at its best and the sound remains both powerful and precise.

Wie effizient ist der Radioactive GZRW 250-D2 FLAT?

The efficiency of the Radioactive GZRW 250-D2 FLAT is specified at 84 dB, which describes the efficiency of the subwoofer in converting electrical energy into sound. A higher efficiency means that less power consumption is required to achieve a certain volume level, which is particularly advantageous in mobile audio systems. This efficiency, combined with the ferrite drive and the 50 mm copper voice coil, ensures that the subwoofer sounds clean and undistorted even at higher volumes.

Welche besondere Schwingspule hat der Radioactive GZRW 250-D2 FLAT?

The Radioactive GZRW 250-D2 FLAT is equipped with a high-quality 50 mm copper voice coil. This voice coil offers improved heat dissipation and higher load capacity. By using copper in the voice coil, an optimal balance between conductivity and mechanical strength is ensured, which enhances the reliability and durability of the subwoofer. The 50 mm dimension also provides an extended excursion and allows for the reproduction of deep frequencies with high precision and without loss of performance.

Welche Tipps gibt es zur Installation des Radioactive GZRW 250-D2 FLAT?

When installing the Radioactive GZRW 250-D2 FLAT, it is important to consider the flat structure as well as the dimensions. With a mounting diameter of 232 mm and a mounting depth of only 85 mm, this subwoofer is excellent for vehicles with limited space. Before installation, the available space should be measured and a suitable position within the vehicle should be chosen. Note that the subwoofer is securely mounted to avoid vibrations – this optimizes sound reproduction and minimizes potential structural stress.

Welche Besondere Materialien hat der Stahlkorb des Radioactive GZRW 250-D2 FLAT?

The Radioactive GZRW 250-D2 FLAT features a steel basket in GZ design, known for its flat shape. This specially designed steel basket provides increased mechanical stability and helps support the overall structure of the subwoofer. The construction simultaneously reduces unwanted resonances and vibrations, resulting in a clean and uncolored sound. The steel material in the basket design ensures that the subwoofer retains its shape and remains durable even under heavy use. The flat design is ideal for tight installation spaces.

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!
