Frequent questions about Hydrogen GZHW 16SPL

Welche Leistungsdaten hat der Hydrogen GZHW 16SPL Subwoofer?

The Ground Zero Hydrogen GZHW 16SPL subwoofer offers an RMS power handling of 500 watts and a maximum power handling of 1000 watts. The speaker's efficiency is at 81 dB, making it a powerful audio component for any setup. With a frequency response resonance point of 51 Hz, the subwoofer is particularly suitable for deep bass frequencies. The directional 50 mm copper voice coil is optimized for high power displacement while maintaining consistent audio output. The impedance is extremely flexible at 2 x 2 ohms to support a variety of audio system setups.

Welche technischen Besonderheiten bietet der Ground Zero Hydrogen GZHW 16SPL?

The Hydrogen GZHW 16SPL from Ground Zero has some remarkable technical features. The combination of a robust aluminum die-cast basket and a reinforced paper diaphragm ensures impeccable stability and sound quality. The Klippel optimization allows for precise bass reproduction. Not to be forgotten is the 2-layer polycot centering, which ensures effective diaphragm excursion. The IMPP dust cap with 3D logo gives the subwoofer an impressive appearance and also protects against dust and dirt.

Wie kann ich den GZHW 16SPL in mein Fahrzeug einbauen, und was muss ich dabei beachten?

When installing the Hydrogen GZHW 16SPL, it is important to ensure that the appropriate installation cutout of 153 mm diameter is available, as well as an installation depth of 110 mm. It is essential that there is enough space for air circulation to effectively utilize the performance of the 30 mm maximum excursion (Xmax). The dual 2-ohm impedance allows for flexible connection options, both in series and parallel, to support various amplifier configurations.

Was zeichnet die Membran des Hydrogen GZHW 16SPL aus?

The membrane of the Ground Zero Hydrogen GZHW 16SPL is a reinforced paper model that has been optimized for stiffness and durability. This special reinforcement allows for improved sound reproduction without the risk of distortion at high volumes. The material is also lightweight and resilient, making the subwoofer ideal for high SPL applications with consistent audio quality. Combined with the robust construction of the aluminum die-cast basket, the membrane is a crucial component of the subwoofer.

Welche Rolle spielt die Schwingspule im Hydrogen GZHW 16SPL Subwoofer?

The Ground Zero Hydrogen GZHW 16SPL uses a 50 mm copper voice coil, which is essential for efficient performance at high excursions. This component ensures precise control of the diaphragm movements and optimizes the electrical efficiency of the subwoofer. Copper is the preferred choice due to its excellent conductivity, minimizing distortion and ensuring thermal stability under high loads. The voice coil is therefore central to achieving a balanced sound image without loss of performance.

Wie wirkt sich der Aluminium-Gusskorb auf die Leistungsfähigkeit des GZHW 16SPL aus?

The aluminum die-cast basket of the Hydrogen GZHW 16SPL plays a crucial role in the overall performance of the subwoofer. Aluminum is known for its excellent mechanical properties and light weight. The die-cast basket provides a stable base, prevents resonances, and enhances structural integrity, even under high sound pressure. At the same time, it supports efficient heat distribution to prevent overheating of the internal components, significantly improving the reliability and longevity of the subwoofer.

Warum ist die Polycot Zentrierung beim Ground Zero GZHW 16SPL wichtig?

The 2-layer Polycot centering in the Ground Zero Hydrogen GZHW 16SPL is crucial for controlling the diaphragm movement. This special construction made of a polyester-cotton blend ensures excellent flexibility and restoring force, which supports the performance of the subwoofer at extreme volumes. Especially in SPL applications, precise centering of the diaphragm is essential to prevent unwanted movements. This technology optimizes the response and load capacity of the diaphragm, contributing to a clear and uncolored sound experience.

Für welchen Frequenzbereich ist der Hydrogen GZHW 16SPL optimiert?

The Ground Zero Hydrogen GZHW 16SPL is optimized for low frequencies, significantly characterized by its resonance frequency of 51 Hz. This feature makes it ideal for bass lovers who desire a deep and powerful sound. The long-stroke design, combined with Klippel optimization, ensures precise response even at very low frequencies. This is further supported by the bass level of 81 dB efficiency, which maximizes efficiency in bass-heavy music genres.

Was sind die Thiele Small Parameter des GZHW 16SPL?

The Thiele Small parameters of the Ground Zero Hydrogen GZHW 16SPL are specifically designed for optimized SPL results. The damping factor (Qts) is 0.46, indicating moderate damping to find a balance between bass precision and performance. The equivalent air volume (Vas) is precisely tuned to the enclosure design at 2.8 liters to generate maximum sound pressure. These parameters are essential to ensure optimal sound reproduction and enclosure matching.

Welche Besonderheiten bietet das Design des Ground Zero Hydrogen GZHW 16SPL?

The design of the Ground Zero Hydrogen GZHW 16SPL impresses with an IMPP dustcap featuring a stylized 3D logo that is not only aesthetically pleasing but also contributes to structural strength. This cap protects the internal components from dust and dirt. The clever combination of an aluminum die-cast structure for reduced resonances and the specially designed dustcap makes this subwoofer an excellent choice for audio enthusiasts who value not only performance but also visual aspects.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
