Frequent questions about Iridium GZIW 165

Welche technischen Merkmale bietet der Iridium GZIW 165?

The Iridium GZIW 165 from Ground Zero is a high-quality 16.5 cm subwoofer with an optimized 38 mm copper voice coil. The diaphragm is made of a stable IMPP structure, which ensures outstanding sound characteristics, and is equipped with a 3D structure to minimize partial vibrations. A durable rubber surround and a polycotton centering guarantee longevity and stability during operation. The resonance-optimized steel basket construction and the pressure contact connection allow for easy installation and reliable sound transmission. The subwoofer has an impedance of 4 ohms and a maximum power handling of 100 watts RMS.

Wie beeinflusst die IMPP-Membran des Iridium GZIW 165 den Klang?

The IMPP membrane of the Iridium GZIW 165 is a crucial element for sound enhancement. It is made of polypropylene, which, due to its rigid yet lightweight structure, is particularly low in resonance, resulting in minimal distortion and clear sound reproduction. Additionally, the special 3D structure of the membrane reduces partial vibrations, leading to a more balanced and precise sound. This subwoofer thus ensures excellent sound quality that reproduces the original sound without distortion. Thanks to this design, the GZIW 165 is an ideal choice for audiophiles who value pure sound.

Welche Thiele-Small-Parameter besitzt der Ground Zero Iridium GZIW 165?

The Thiele-Small parameters of the Ground Zero Iridium GZIW 165 are important indicators of its performance. The subwoofer has a Qms of 10.70, which represents its mechanical quality. The Qes is at 0.43, while the Qts is at 0.41, describing the overall quality of the speaker. The Vas is 9.1 liters, which is the volume needed for bass reflex tuning. Mms is at 40.4 grams and describes the moving mass of the diaphragm. The BL value of 9.46 indicates the force acting on the voice coil, which affects the efficiency of the speaker. These parameters are essential for optimal integration into the audio system.

Wie hoch ist die Einbauteife des Iridium GZIW 165?

The Iridium GZIW 165 from Ground Zero has a mounting depth of 79 mm, which is important to ensure compatibility with various vehicle models. The installation dimensions are crucial for the correct fit and mechanics within the given enclosure design. With a mounting diameter of 147 mm and an outer diameter of 168 mm, this subwoofer can be integrated into most standardized box enclosures. Ensure that there is enough space to guarantee optimal sound direction and no contact with other components of your vehicle. Also, pay attention to a solid anchoring to minimize vibrations.

Warum ist der Resonanzarme Stahlkorb des GZIW 165 wichtig?

The resonance-optimized steel basket of the GZIW 165 is central to its sound performance, as it provides a stable base that minimizes unwanted vibrations and thus avoids sound distortions. A resonance-optimized frame is particularly important, as it keeps the movement of the diaphragm optimally under control, thereby supporting a clean sound image. This steel basket significantly contributes to the structural integrity of the subwoofer and enables the GZIW 165 to achieve precise and focused bass reproduction, making it the ideal choice for audiophiles who appreciate high-precision performance.

Welche Verstärkerleistung wird für den GZIW 165 empfohlen?

For the Ground Zero Iridium GZIW 165, an amplifier power of 60 to 150 watts is recommended to optimally operate the subwoofer. This power range ensures that the subwoofer achieves its maximum sound quality without risking damage from overload. With this power, it can easily utilize the specified RMS load capacity of 100 watts. When the amplifier is operated within these power parameters, clear, distortion-free bass reproduction is guaranteed. This makes it the ideal complement in a well-coordinated sound system, where power and sound quality are of utmost importance.

Wie beeinflusst die Kupfer Schwingspule den Klang des Iridium GZIW 165?

The 38 mm copper voice coil of the Iridium GZIW 165 plays a crucial role in the sound reproduction of the subwoofer. Copper is known for its excellent conductivity and heat dissipation, which means it efficiently conducts energy through the voice coil while optimizing heat release. This allows the subwoofer to sound clean at high volumes without overheating. The voice coil also contributes to the stiffness and stability of the diaphragm movements, minimizing distortion and ensuring a clear, precise sound.

Kann der Iridium GZIW 165 mit meinem Auto kompatibel sein?

The Iridium GZIW 165 has special dimensions that are crucial for compatibility with many car models. With an outer diameter of 168 mm, an installation diameter of 147 mm, and an installation depth of 79 mm, the subwoofer is designed to fit into most standardized subwoofer boxes. Check the dimensions of your vehicle to ensure that the subwoofer can be installed correctly. Especially if you do not have specific car brands in your description, make sure there is enough space and a suitable enclosure structure.

Welche Auswirkung hat die Langlebige Gummisicke auf die Dauerhaftigkeit des Iridium GZIW 165?

The durable rubber surround of the Iridium GZIW 165 significantly contributes to the durability and stability of the subwoofer. Rubber is a material that is widely used due to its flexibility and resistance to aging and weather influences. This surround ensures a uniform return of the diaphragm to its original position, thus providing maximum stability during diaphragm movement. This reduces the risk of material fatigue and extends the lifespan of the speaker, even with intensive use. This is especially important for users who regularly prefer high volumes.

Wie hoch ist der Wirkungsgrad des Iridium GZIW 165 und warum ist er wichtig?

The efficiency of the Iridium GZIW 165 is 85.5 dB SPL at 1 Watt/1 meter, which is a measure of how efficiently the subwoofer converts electrical power into sound. A higher efficiency means that the speaker requires less energy to achieve a certain volume level, which is advantageous in energy-efficient systems. This efficiency allows the device to deliver clear and powerful bass even without power-intensive amplifiers. For audio enthusiasts, high efficiency is crucial for optimizing performance without additional amplifier load.

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!
