Frequent questions about Iridium GZIK 165SPL

Welche technischen Merkmale hat der Iridium GZIK 165SPL Tiefmitteltöner?

The Iridium GZIK 165SPL from Ground Zero features a HQPP membrane with a 3D honeycomb structure that enables an outstanding sound experience. The resonance-optimized steel basket structure provides stability, while the highly efficient 3 Ohm version optimizes performance. With a diameter of 165 mm and a power handling of 80/120 watts, this SPL mid-bass driver is ideal for powerful audio applications. Equipped with a long-stroke rubber surround and a 25 mm copper voice coil, it maximizes the effect, while the included hexagon protective grille offers additional protection. Compliance with Euro-DIN installation dimensions significantly simplifies integration.

Wie hoch ist der Wirkungsgrad des Iridium GZIK 165SPL?

The efficiency of the Iridium GZIK 165SPL is 87 dB, which gives this speaker from Ground Zero a high efficiency in audio playback. This technical characteristic is crucial for performance, as it defines the ratio of emitted acoustic power to electrical input power. A higher efficiency means that less energy is converted into unwanted heat, and more of it is used for sound production. This results in a powerful and clear sound, even at lower output levels. For audio enthusiasts, this is ideal to ensure an impressive listening experience.

Welchen Frequenzgang deckt der Iridium GZIK 165SPL ab?

The frequency response of the Iridium GZIK 165SPL mid-bass speaker ranges from 60 Hz to 4 kHz. This bandwidth allows the speaker to cover deep bass tones up to clearly defined mids. The lower limit of 60 Hz ensures solid bass, while the upper limit of 4 kHz ensures that higher mid frequencies are reproduced cleanly and precisely. This makes this speaker the optimal choice for demanding audio applications where detailed sound reproduction is required.

Wie beeinflusst die HQPP Membran die Leistung des Iridium GZIK 165SPL?

The HQPP membrane of the Iridium GZIK 165SPL is specifically designed with a 3D honeycomb structure that offers enormous advantages in terms of sound efficiency and precision. This structure optimizes the stiffness of the membrane and minimizes distortion, resulting in clear and precise sound. Especially at low frequencies, the membrane relieves the speaker motor due to its stable construction, ensuring powerful bass reproduction. This feature makes the GZIK 165SPL ideally suited for users who value detailed and powerful audio playback.

Wie sieht die Installation des Iridium GZIK 165SPL im Auto aus?

The installation of the Iridium GZIK 165SPL from Ground Zero in the car is significantly facilitated by adhering to the Euro-DIN installation dimensions. With an installation diameter of 142.5 mm and an installation depth of 68 mm, the speaker can be integrated into a variety of vehicle models. The included resonance-optimized steel basket offers additional flexibility in placement and ensures that the speaker sits securely and stably. The use of solder connections allows for a reliable electrical connection, while the hexagon protective grille provides protection against mechanical influences.

Welche Rolle spielt der Ferritmagnet im Iridium GZIK 165SPL?

The ferrite magnet of the Iridium GZIK 165SPL significantly contributes to the performance of this Ground Zero speaker. As a central component of the drive system, the magnet generates the necessary magnetic field that sets the voice coil in motion. This movement ultimately results in sound waves. Ferrite, a ceramic material, is not only cost-effective but also provides a constant magnetic performance across a wide voltage range. This allows the speaker to achieve high volumes and also offers excellent stability and consistency of sound quality even under intense use.

Was sind die Abmessungen des Iridium GZIK 165SPL Lautsprechers?

The Iridium GZIK 165SPL has a diameter of 165 mm, ideal for standardized speaker openings in vehicles. With a mounting depth of 68 mm, it can be easily integrated into existing installation slots without requiring additional space in the interior. These dimensions make it compatible with most car models that use Euro-DIN installation sizes. The mounting diameter is 142.5 mm, ensuring easy installation. Therefore, the Iridium GZIK 165SPL is a flexible choice for numerous installation environments where space constraints exist.

Wie groß ist die Schwingspule im Iridium GZIK 165SPL?

The voice coil of the Iridium GZIK 165SPL is optimized with a size of 25 mm to maximize both the efficiency and performance of the speaker. This dimension allows for considerable control of the diaphragm's movement and ensures high precision in audio playback. A larger voice coil like this also offers advantages in terms of heat dissipation and reduces the risk of overheating, especially at high volumes. This is particularly relevant for users who operate the speaker for extended periods and under intense conditions.

Was bewirkt die Langhub-Gummisicke beim Iridium GZIK 165SPL?

The long-stroke rubber surround of the Iridium GZIK 165SPL from Ground Zero is designed to allow for larger diaphragm strokes without distortion, resulting in powerful bass reproduction. This surround ensures stable diaphragm movement and reduces mechanical stress at high volumes. Due to its material, it has excellent restoring properties and is well-suited to dampen vibrations. This is particularly advantageous for users who listen to music intensively and want a dynamic, distortion-free playback at high sound pressure.

Wie wirkt sich die resonanzarme Stahlkorbstruktur auf den Klang aus?

The resonance-optimized steel basket structure in the Iridium GZIK 165SPL minimizes unwanted vibrations that can affect the sound. Thanks to this construction, stability is increased and the resonance frequencies are lowered, thereby avoiding undesirable background noise. This feature is crucial for clear audio reproduction, as the steel basket reliably holds the diaphragm in place and allows for even sound distribution. This is particularly valuable for music enthusiasts who appreciate crystal-clear sound without distortion and want to achieve clear results in demanding acoustic environments.

Massive MiniMonster!

What a Minimonster, 18Liter ported box,tuned to 32hz and plays very loud and even good on lows. Even when i'm underpowering and only giving 350-400watts max. I really love this 6,5 monster, also the aluminium basket is very strong and solid and has great venting for the voice coil. Having rubber surround and carbon fiber cone just makes this even more indestructible

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.
