This remote control allows for comfortable control of the amplifier from a distance, which is particularly convenient when the amplifier is installed in hard-to-reach places. With the remote control, settings such as volume or other adjustments can be easily made without having to physically access the amplifier. This option significantly enhances user comfort and provides users with the ability to change settings flexibly and effortlessly.

Wie effizient ist der Kühlkörper des Radioactive GZRA 2HD Verstärkers?

The Radioactive GZRA 2HD amplifier is equipped with a highly efficient heat sink that ensures effective heat dissipation. This is particularly important as amplifiers generate heat at high power levels, which must be dissipated to avoid overheating and associated damage. The heat sink helps maintain a stable operating temperature, maximizing the performance and lifespan of the amplifier. Especially in intensive applications, such as constant high volume, the efficient heat sink proves to be indispensable for ensuring smooth operation.

Welche Funktionen bietet die variable Aktivweiche im Radioactive GZRA 2HD?

The variable active crossover of the Radioactive GZRA 2HD offers a wide adjustment range and allows for detailed customization of frequency ranges. It is equipped with HPF, LPF, and BPF filters, enabling frequencies to be individually filtered and optimized. This flexibility allows the audio system to be optimally tailored to personal preferences or specific acoustic requirements of a vehicle. Especially for audiophiles who value finely tuned sound, the variable active crossover provides the ability to precisely adjust highs, lows, and mids, thus creating a customized listening experience.

Welches Frequenzspektrum kann der Radioactive GZRA 2HD Verstärker abdecken?

The Radioactive GZRA 2HD amplifier covers a frequency spectrum from 10 to 250 Hz. This spectrum allows for the precise amplification of both extremely low and higher frequencies. This bandwidth is ideal for car enthusiasts who appreciate strong bass performance, as the amplifier provides powerful clarity and impact, especially in the lower frequency ranges. The amplifier's ability to operate in this range makes it the perfect choice for demanding audio tasks that require accurate reproduction of audio frequencies.

Wie kompakt ist der Radioactive GZRA 2HD Verstärker für die Installation in Fahrzeugen?

The Radioactive GZRA 2HD is designed to be particularly compact with dimensions of 186 x 268 x 52 mm, making installation in vehicles easier.

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!
