Frequently Asked Questions about Uranium GZHT 25S

What are the main features of the Ground Zero Uranium GZHT 25S Tweeter?

The Uranium GZHT 25S Tweeter from Ground Zero features a silk dome tweeter with a diameter of 25 mm. It has a maximum power of 110 watts and a nominal impedance of 4 ohms. The tweeter is equipped with a ventilated neodymium motor and a coated silk dome. Additionally, it offers ferrofluid cooling and has a low installation depth of only 16 mm. The frequency response ranges from 2500 Hz to 24 kHz, resulting in a clear and precise sound image.

What power and impedance does the Uranium GZHT 25S have?

The Ground Zero Uranium GZHT 25S offers a maximum power of 110 watts with a nominal impedance of 4 ohms. Its continuous power handling is 70 watts RMS, which, combined with the silk dome, ensures reliable sound performance. It is therefore ideal for discerning music lovers. The 4-ohm impedance is typical for car hi-fi components and ensures optimal compatibility with common car audio amplifiers.

How is the Ground Zero Uranium GZHT 25S Tweeter cooled?

The GZHT 25S Tweeter features ferrofluid cooling, which allows for efficient heat exchange. This technology helps maintain the stability and performance of the tweeter at high volumes. Combined with the ventilated neodymium motor, temperature development is minimized, making the tweeter more durable and preventing distortion at high power levels.

What is the installation depth and diameter of the Ground Zero Uranium GZHT 25S?

The Uranium GZHT 25S Tweeter has an installation depth of only 16 mm and an outer diameter of 25 mm. The installation diameter is 48 mm. These compact dimensions facilitate integration into existing audio systems, especially in tight installation situations. The low installation depth allows for versatile placement, such as in the A-pillars or dashboard of vehicles.

What materials are used for the housing and dome of the Ground Zero GZHT 25S?

The Ground Zero Uranium GZHT 25S uses high-quality materials. The dome is made of coated silk, which provides smooth and clear sound colors. The housing and installation frame are made of robust composite material, ensuring stability and durability. This combination of materials not only guarantees outstanding sound but also high resistance to environmental influences.

What is the frequency response of the Ground Zero Uranium GZHT 25S?

The Ground Zero Uranium GZHT 25S offers a wide frequency range from 2500 Hz to 24 kHz. This range allows for accurate reproduction of high frequencies, ensuring a clear and detailed sound image. The resonance frequency is at 1550 Hz, providing an excellent foundation for integration into a two-way or multi-way system. These technical specifications make it ideal for audiophiles who appreciate detailed high-frequency sounds.

What is the resonance frequency of the Ground Zero Uranium GZHT 25S?

The resonance frequency of the Uranium GZHT 25S tweeter is 1550 Hz. This frequency defines the point at which the tweeter achieves its optimal performance. It is a crucial parameter in tuning the speaker system. With a resonance frequency of 1550 Hz, the GZHT 25S is particularly suitable for systems that require precise frequency separation between the midrange and high-frequency ranges.

What tips are there for installing the Ground Zero Uranium GZHT 25S tweeter?

When installing the Ground Zero Uranium GZHT 25S, you should consider the shallow installation depth of 16 mm and the installation diameter of 48 mm. These dimensions allow for flexible mounting, such as in the A-pillar or dashboard of your vehicle. You should ensure that the installation location is well-ventilated to optimize the performance of the ventilated neodymium motor. Suitable cables are necessary for the connection, and the included connection wires facilitate this process.

Is the Ground Zero Uranium GZHT 25S compatible with my car?

The Ground Zero Uranium GZHT 25S tweeter is compatible with many vehicle models thanks to its compact dimensions. The shallow installation depth of 16 mm and the installation diameter of 48 mm allow for easy integration into various car interiors. Although no specific car brands are mentioned in the product description, these dimensions fit ideally into many common vehicle types. However, it is advisable to check your vehicle's installation guidelines before installation.

How does the neodymium motor affect the performance of the Uranium GZHT 25S?

The ventilated neodymium motor of the Ground Zero Uranium GZHT 25S ensures efficient magnetic field strength, precisely controlling the movements of the silk dome. The ventilation of the motor prevents overheating, supporting long-term stability and keeping the sound clean at high volumes. This technology ensures that the tweeter maintains its excellent sound quality even under intense use, providing fine sound resolution, especially in the high-frequency range.

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.
