Frequently Asked Questions about Iridium GZIK 165SPL

What are the technical features of the Iridium GZIK 165SPL mid-bass speaker?

The Iridium GZIK 165SPL from Ground Zero features an 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 design optimizes performance. With a diameter of 165 mm and a power handling of 80/120 watts, this SPL mid-bass speaker 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.

What is the efficiency of the Iridium GZIK 165SPL?

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

What frequency range does the Iridium GZIK 165SPL cover?

The frequency range of the Iridium GZIK 165SPL mid-bass speaker extends 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.

How does the HQPP membrane affect the performance of the 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.

What does the installation of the Iridium GZIK 165SPL in the car look like?

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 a mounting 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.

What role does the ferrite magnet play in the Iridium GZIK 165SPL?

The ferrite magnet of the Iridium GZIK 165SPL is crucial 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 consistent magnetic performance across a wide voltage range. This enables the speaker to achieve high volumes while maintaining excellent stability and consistency in sound quality, even under intense use.

What are the dimensions of the Iridium GZIK 165SPL speaker?

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.

What is the size of the voice coil in the Iridium GZIK 165SPL?

The voice coil of the Iridium GZIK 165SPL is optimized at a size of 25 mm to maximize both the efficiency and performance of the speaker. This dimension allows for significant 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.

What effect does the long-stroke rubber surround have on the Iridium GZIK 165SPL?

The long-stroke rubber surround of the Iridium GZIK 165SPL from Ground Zero is designed to allow for larger diaphragm excursions without distortion, resulting in powerful bass reproduction. This surround ensures stable movement of the diaphragm 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 especially beneficial for users who listen to music intensely and want a dynamic, distortion-free playback at high sound pressure levels.

How does the resonance-optimized steel basket structure affect the sound?

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 resonance frequencies are lowered, preventing unwanted background noise. This feature is crucial for clear audio playback, 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.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
