It offers a balanced performance with high sound fidelity and efficient energy consumption. This technology minimizes distortion, resulting in clearer and more precise playback. Especially at medium to high volume levels, the audio quality remains consistent, making this amplifier ideal for Hi-Fi environments. The stable performance under different loads sustainably enhances the listening experience in various acoustic scenarios.

Welche Ausgangsleistung bietet der Iridium GZIA 100.2 bei unterschiedlichen Impedanzen?

The Iridium GZIA 100.2 features flexible output power, tailored to different impedances. At an impedance of 4Ω, it delivers 2x 75 watts RMS, while at 2Ω it reaches 2x 120 watts RMS. In bridged operation at 4Ω, it can provide a power output of 240 watts RMS. The amplifier can achieve a maximum power output of up to 300 watts according to CEA-2006A with 10% THD+N. These power specifications allow the amplifier to be used efficiently in a variety of speaker configurations to optimize both volume and clarity.

Welche Rolle spielt die variable Aktivweiche im Klang des Iridium GZIA 100.2?

The variable active crossover of the Iridium GZIA 100.2 allows you to precisely control the frequency range that the amplifier should amplify. This helps to tailor the sound to the specific requirements of the vehicle or the speakers. For example, you can boost or attenuate certain frequencies through the crossover filters, which is helpful when adapting to speakers with specific power requirements. These adjustment options contribute to an acoustically balanced sound image by controlling specific resonance characteristics more precisely than standard settings.

Welche Vorteile bietet der Hochpegel-Eingang mit Auto-On Funktion beim Iridium GZIA 100.2?

The high-level input with Auto-On function of the Iridium GZIA 100.2 significantly simplifies installation, especially in existing audio systems that do not have a separate amplifier output. This input allows for direct connection to the speaker outputs of the factory stereo system by detecting the voltage and automatically activating the amplifier. This means you do not need a separate remote cable connection. This simplicity makes the Iridium GZIA 100.2 an extremely practical option for enhancing existing audio systems without much effort.

Welche Rolle spielt der schwarz eloxierte Kühlkörper für die Performance des Iridium GZIA 100.2?

The black anodized heat sink of the Iridium GZIA 100.2 is not only an aesthetic element but also essential for the thermal efficiency of the amplifier. The choice of material and design ensure that the heat generated during operation is efficiently dissipated. This prevents heat buildup and reduces the need for additional fans that could create noise. As a result, the heat sink enables quiet, reliable operation. Especially during long listening sessions or at high volumes, it ensures the stability and longevity of the amplifier.

Welche Installationshinweise sind für den Iridium GZIA 100.2 zu beachten?

When installing the Iridium GZIA 100.2, you should first consider the dimensions of 168 x 49 x 175 mm to ensure that there is enough space available. The generously sized connections facilitate the cable management process. For optimal sound quality, the amplifier should be installed in a location with good ventilation to support cooling performance. The mounting surface should be flat and low in vibrations. It is advisable to carry out the wiring carefully to ensure the best possible performance without interruptions or interference.

Welche Frequenzgang-Optionen bietet der Iridium GZIA 100.2?

The Iridium GZIA 100.2 offers a frequency response of 8 Hz to 28 kHz, providing an enormous range for sound adjustments. This option allows for the reproduction of deep bass as well as very high tones, covering a wide spectrum of musical genres. Especially if you enjoy listening to both bass-intensive music and acoustic pieces, you will benefit from this broad frequency coverage. The configuration of the frequency response is further supported by the variable active crossover, which allows for targeted adjustments.

Welche Bass Boost Einstellungen bietet der Iridium GZIA 100.2?

The Iridium GZIA 100.2 offers a Bass Boost function that allows you to enhance the lower frequencies for a more powerful and impressive sound experience. This setting is particularly useful for music genres that benefit from more intense bass lines, such as hip-hop or electronic music. The Bass Boost function helps to customize the sound character without the need for external equalizers or signal processors. With this integration, you can control the dynamics and depth of your music directly at the amplifier.

Mit welchen Automarken und Modellen ist der Iridium GZIA 100.2 kompatibel?

The Iridium GZIA 100.2 can be installed in a variety of vehicles, as it is universally compatible with most car brands, provided there is space and wiring available. No specific brands or models are required for a successful installation. Thanks to the high-level inputs, it can be connected to many factory sound systems that offer speaker outputs.

Super guter Subwoofer

Super Subwoofer mit extrem tiefem Bass. Die Kabel sind dick und hochwertig verarbeitet. Es gibt nichts zu beanstanden. Absolut empfehlenswert.

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 .

X-10 v3 d2

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!
