Frequently Asked Questions about Uranium GZUC 165.3SQ-ACT

What technical features does the Uranium GZUC 165.3SQ-ACT Speaker Set have?

The Uranium GZUC 165.3SQ-ACT from Ground Zero is manufactured as a 6.5" 3-way component speaker system, consisting of a 165 mm woofer, a 55 mm midrange driver, and a 28 mm silk dome tweeter. It has a power handling capacity of 140 / 230 watts and offers a sensitivity of 89 dB. The frequency response ranges from 40 Hz to 25 kHz. Notably, it features a black anodized aluminum diaphragm and a GZ aluminum die-cast basket, ensuring robustness. With the GZ design hexagon grille and the universal 4-ohm design, it is versatile.

What is the frequency response of the Ground Zero Uranium GZUC 165.3SQ-ACT?

The frequency response of the Uranium GZUC 165.3SQ-ACT speaker ranges from 40 Hz to 25 kHz. Notably, the tweeter, the GZUT 28SQ, covers a frequency range of 2500 Hz to 25 kHz, while the midrange driver GZUM 55SQ operates in the range of 500 Hz to 11 kHz. The woofer/midrange speaker GZUK 165SQ operates between 40 Hz and 3500 Hz, resulting in a harmonious reproduction of low, mid, and high tones, elevating the sound experience to a new level.

What are the power handling capacities of the speakers in the GZUC 165.3SQ-ACT system?

The Uranium GZUC 165.3SQ-ACT speaker system comes with different power handling capacities: The tweeter GZUT 28SQ can handle loads of 80 watts RMS up to a maximum of 130 watts, while the midrange driver GZUM 55SQ is rated for 90 watts RMS up to 150 watts. The woofer/midrange speaker GZUK 165SQ has an RMS of 120 watts and a maximum power handling capacity of 180 watts. These values are crucial for extracting optimal sound from the speakers while maintaining maximum efficiency.

What are the unique design features of the Uranium GZUC 165.3SQ-ACT?

The construction of the Uranium GZUC 165.3SQ-ACT impresses with black anodized aluminum membranes and a GZ aluminum die-cast basket, which are used in both the mid-bass and midrange drivers. These materials maximize durability. Furthermore, the 50 mm copper voice coil in the mid-bass driver ensures efficient sound transmission. The resource-saving combination of rubber surrounds and neodymium drive generates a clear and precise sound. The design is completed with a GZ design hexagon grille to protect the sensitive components.

What role does the neodymium drive play in the Ground Zero Uranium GZUC 165.3SQ-ACT?

The neodymium drive in the Uranium GZUC 165.3SQ-ACT plays a central role regarding sound quality and efficiency. Due to its high magnetic flux density, it allows for a lighter and smaller construction without sacrificing performance. The tweeter GZUT 28SQ and the midrange driver GZUM 55SQ, as well as the sub/midrange speaker GZUK 165SQ, utilize this drive to ensure sharp, precise sound reproduction across a wide frequency range. Neodymium thus ensures that sounds are reproduced clearly and in detail, regardless of volume.

How is the impedance managed in the Uranium GZUC 165.3SQ-ACT?

In the Uranium GZUC 165.3SQ-ACT speaker set, impedance management is achieved through thoughtful technical configurations, as the speakers are designed with a universal 4-ohm specification, allowing for general integration into many audio environments. The midrange driver GZUM 55SQ has an impedance of 4 ohms, while the tweeter GZUT 28SQ also operates at 4 ohms. This consistency allows for coherent signal processing and ensures that power requirements remain constant at all times, minimizing electrical load during operation.

What are the installation depths of the Uranium GZUC 165.3SQ-ACT?

When installing the Uranium GZUC 165.3SQ-ACT speaker system, the installation depth of the individual components should be considered: The tweeter GZUT 28SQ requires an installation depth of only 18 mm, allowing for flexible arrangement in the vehicle. The midrange driver GZUM 55SQ has an installation depth of 35 mm, while the sub/midrange speaker GZUK 165SQ has the deepest installation depth at 63 mm. These specifications are particularly relevant for checking compatibility in a vehicle and allow for precise integration without compromising sound quality.

What resonance frequencies are crucial in the Uranium GZUC 165.3SQ-ACT?

The resonance frequencies of the components of the Uranium GZUC 165.3SQ-ACT Speaker Set play a significant role in the sound characteristics. The Tweeter GZUT 28SQ has a resonance frequency of 1300 Hz, allowing it to deliver clear and detailed highs. The Midrange GZUM 55SQ resonates at 353 Hz, emphasizing its ability to present details in the mid-frequency range. The Woofer/Midrange GZUK 165SQ shows a resonance frequency of 54.6 Hz, ensuring that deep tones are transmitted with precision and impact.

How can the Uranium GZUC 165.3SQ-ACT be installed in a vehicle?

The installation of the Ground Zero Uranium GZUC 165.3SQ-ACT Speaker Set in a vehicle is carried out considering the specific dimensions. The Tweeter GZUT 28SQ fits optimally in many areas with a mounting diameter of 48 mm. The Midrange has a mounting diameter of 69 mm, and the Woofer GZUK 165SQ measures 144 mm, making it the largest component. It is essential to ensure that the speakers fit into the existing cutouts to avoid vibrations and not negatively affect sound quality.

What does the designation GZ Design Hexagon grille in the Uranium GZUC 165.3SQ-ACT refer to?

The designation GZ Design Hexagon grille in the Uranium GZUC 165.3SQ-ACT refers to a specially designed grille that protects the sensitive speaker membranes. These grilles are designed in an aesthetic hexagonal shape, are robust, and are discreetly integrated into the design. They prevent physical damage from foreign objects, thus reducing the risk of speaker failure. At the same time, they ensure that sound quality is not affected by their neutral structure, which provides high sound fidelity and long-term reliability of the speakers.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
