The black anodized aluminum membranes of the mid-bass and midrange drivers, in conjunction with the 28 mm silk dome tweeter, provide a comprehensive sound experience. It includes a crossover and hexagon protection grille. The power handling is 140/230 watts, and the frequency response ranges from 40 Hz to 25 kHz. The linearization of the neodymium driver and the universal 4-ohm design further enhance the performance and adaptability of this impressive speaker system.

Wie ist die Belastbarkeit und der Wirkungsgrad des GZUT 28SQ Hochtöners?

The GZUT 28SQ tweeter in the Uranium GZUC 165.3SQ speaker set from Ground Zero has an excellent load capacity of 80 for RMS rated power and 130 watts for maximum rated power. The efficiency is 90 dB, which guarantees an efficient conversion of input power into sound. Particularly noteworthy is the frequency response from 2500 Hz to 25 kHz, making the tweeter ideal for detailed reproduction up to the highest frequencies. A high-pass filter at 3000 Hz with a slope of 12 dB/oct is recommended to keep the sound clear and free of interference.

Welche Materialien werden im Uranium GZUC 165.3SQ eingesetzt?

In the loudspeaker set Uranium GZUC 165.3SQ from Ground Zero, a variety of high-quality materials are used to ensure excellent sound fidelity. The membranes of the bass speakers and the midrange driver are made of anodized aluminum, making them low-resonance and stable. The voice coils are made of copper, which ensures good conductivity. The neodymium drive is held by a GZ aluminum die-cast basket, which ensures structural integrity and durability. These materials significantly contribute to the robustness and performance of the loudspeaker set.

Welche Frequenzweiche ist im Uranium GZUC 165.3SQ enthalten?

The Uranium GZUC 165.3SQ from Ground Zero is equipped with an integrated crossover that allows for a smooth transition between the frequency ranges of the individual speaker components. The tweeters cover a frequency range from 2500 Hz to 25 kHz, while the midrange drivers are designed for frequencies between 200 Hz and 6 kHz. The mid-bass driver covers from 40 Hz to 3500 Hz, with a crossover frequency of 4800 Hz. All of this is regulated by the crossover, which optimizes the sound balance between the speakers.

Wie groß ist der Einbaudurchmesser und die Einbautiefe der Mitteltöner im Uranium GZUC 165.3SQ?

The speaker set Uranium GZUC 165.3SQ from Ground Zero uses midrange drivers that are specifically designed for easy installation. The installation diameter of the midrange drivers is 77 mm and the installation depth is 35 mm. These dimensions allow for seamless integration into most speaker enclosures without compromising sound quality. It is important to consider the space conditions of the installation location to ensure that there is enough room for the correct alignment and functionality of the components.

Welche Rolle spielen die Gummisicken im Uranium GZUC 165.3SQ?

The rubber surrounds used in the Uranium GZUC 165.3SQ by Ground Zero are crucial for the flexibility and optimal mobility of the membrane. They allow the membrane to swing back and forth precisely by providing a balance between stability and freedom of movement. This directly affects the sound waves emitted into the room and supports the generation of a clear and undistorted sound image. Especially if you enjoy listening to loud music, rubber surrounds play a significant role in preventing sound distortions.

Wie wird der Neodym-Antrieb im Uranium GZUC 165.3SQ Lautsprecherset genutzt?

The neodymium drive in the Uranium GZUC 165.3SQ speaker set from Ground Zero gives the speakers high efficiency and magnetic force, significantly enhancing performance. The neodymium magnets allow for a stronger attraction than conventional ferrite magnets, resulting in more precise sound control. This leads to improved bass reproduction and higher sensitivity with a lower weight of the overall speaker components. This facilitates installation and reduces the overall load on the speaker suspension.

Welche Kompatibilität bietet das Uranium GZUC 165.3SQ in der universellen 4-Ohm-Ausführung?

The universal 4-ohm version of the Uranium GZUC 165.3SQ speaker set from Ground Zero offers broad compatibility with a variety of amplifiers and audio systems. This impedance provides a favorable compromise between volume and sound quality, as it is generally standardized for both home and vehicle audio systems. However, when installing, you should ensure that your existing audio hardware is set to or designed for 4 ohms to guarantee even power distribution and make the best use of the speakers.

Was sind die Maße für den Einbau des Tiefmitteltöners im Uranium GZUC 165.3SQ?

The Uranium GZUC 165.3SQ from Ground Zero features midrange drivers designed for a mounting size of 165 mm in diameter. The required mounting diameter is 144 mm, accompanied by a mounting depth of 63 mm. These dimensions are crucial for correctly and securely fitting the speaker into the enclosure or designated space. If you encounter gaps or irregularities when integrating it into your vehicle or home theater system, these measurements can serve as a guide for adjustments or mounting aids to ensure optimal sound.

Welche Vorteile bieten die Seidenkalotten im Hochtöner des Uranium GZUC 165.3SQ?

The silk domes used in the tweeter of the Uranium GZUC 165.3SQ by Ground Zero have several advantages, particularly due to their excellent property of reproducing sound softly and in detail. Silk as a dome material is known for its lower mass compared to other materials, which allows for higher sensitivity and faster response time. This results in clear reproduction of high frequencies without producing hardness or distortion. Especially in acoustically demanding environments, silk domes play a crucial role in sound finesse and dynamics.
