Frequent questions about Nuclear GZNW 38SPL


Welche Leistungsdaten hat der Nuclear GZNW 38SPL Subwoofer?

The Nuclear GZNW 38SPL from Ground Zero offers impressive performance data. With an RMS power handling of 3500 watts and a peak output power of 7000 watts, this 15-inch subwoofer is designed for the highest demands. The efficiency is 88.5 dB, which, in combination with a recommended amplifier power of 2000 to 7000 watts, guarantees powerful playback. The impedance can be selected between 2x1 ohm or 2x2 ohm depending on the setup. For enthusiasts of dynamic bass reproduction, the large excursion of up to 80 mm is remarkable.

Was zeichnet die Konstruktion des Nuclear GZNW 38SPL aus?

The subwoofer is characterized by several innovative design features. A massive aluminum die-cast basket provides the necessary stability to handle the enormous forces at high volumes. The 75 mm CCA round wire voice coil ensures excellent heat dissipation, while the 4-layer Nomex centering keeps the structure firmly in place. The Klippel®-optimized design also contributes to performance by minimizing distortion and improving linearity. This interplay increases longevity and offers excellent sound quality.

Wie montiere ich den Nuclear GZNW 38SPL korrekt?

For the installation of the Nuclear GZNW 38SPL, a stable and secure location is recommended to support the weight of 36 kg. The installation opening should have a diameter of 358 mm, with a maximum installation depth of 269 mm. It is recommended to use a robust subwoofer box that takes into account both the volume and the resonance frequency. A professional installation ensures that the sound is optimally showcased and material damage is avoided.

Welche Materialien werden für die Membran des Subwoofers verwendet?

The membrane of the Nuclear GZNW 38SPL is made of a fiber-reinforced paper that provides additional strength. This special material choice ensures that the membrane can easily withstand high mechanical loads and extreme vibrations without compromising its structure or sound quality. The fiber-reinforced construction also contributes to maintaining the resonance frequencies and ensures precise, punchy bass reproduction. The design is completed with a carbon design dust cap that not only looks good but also supports performance.

Ist der Nuclear GZNW 38SPL mit meinem verstärkersystem kompatibel?

For optimal use, it is important to match the performance requirements of the subwoofer with your amplifier system. The Nuclear GZNW 38SPL requires an amplifier power of 2000 to 7000 watts to fully utilize its capacity. The impedance options of 2x1 ohm or 2x2 ohm provide flexibility for integration into various amplifier systems. An improperly matched combination could impair performance or damage the subwoofer. Therefore, it is advisable to strictly adhere to the power recommendations.

Welche Besonderheiten bietet die Schwingspule des Nuclear GZNW 38SPL?

The voice coil of the Nuclear GZNW 38SPL is made of 75 mm CCA (copper-coated aluminum), which provides an ideal combination of weight and conductivity. This design significantly contributes to effective heat dissipation and reduces the risk of overheating during intense use. The voice coil plays a crucial role in the dynamic frequency response of the subwoofer by enabling fast and precise movements of the diaphragm, which contributes to sound precision and power.

Wie beeinflusst die Nomex Zentrierung die Leistung?

The 4-layer Nomex centering of the Nuclear GZNW 38SPL provides excellent structural support for the entire subwoofer system. Its robust and flexible design allows for a wide excursion of the diaphragm, resulting in increased bass volume. Nomex is known for its resistance to extreme temperature fluctuations and mechanical stresses, significantly enhancing the reliability and lifespan of the product, especially under intense use and high volumes.

Welche Resonanzfrequenz hat der Nuclear GZNW 38SPL und warum ist das wichtig?

The Nuclear GZNW 38SPL has a resonance frequency of 36 Hz. This low frequency is an indication of the wide possibilities in bass reproduction. A lower resonance frequency means that the subwoofer is capable of producing deeper bass tones, which is beneficial for both music playback and home theater applications. Such a frequency profile ensures a powerful and vibrating sound, which is intensified in what is typically demanded in action-packed movie scenes or bass-heavy music.

Was genau bedeutet die Klippel®-Optimierung beim Nuclear GZNW 38SPL?

The Klippel® optimization in the Nuclear GZNW 38SPL means that the subwoofer has been fine-tuned using specific measurement and analysis methods to minimize distortion and improve linearity. This optimization maximizes the performance of the subwoofer by reducing interference factors that can affect sound quality. This technology manages to keep the sound particularly clear, even at high volumes, and ensures that details in the low-frequency range are reproduced accurately and without distortion.

Wie beeinflussen die technischen Parameter die Klangcharakteristik?

The technical parameters of the Nuclear GZNW 38SPL such as Xmax (80 mm), Fs (36 Hz), and Qts (0.52) play a crucial role in the sound characteristics of the subwoofer. A high Xmax value allows for extreme diaphragm excursions, resulting in a voluminous and powerful bass. The resonance frequency Fs ensures the ability to efficiently reproduce low frequencies. The Qts value reflects the overall efficiency and damping of the system, which affects the detail and tonal fidelity at high volume levels.
