The Ground Zero GZPA Reference 4PURE-SQ 4-channel amplifier delivers impressive power at various impedances. At an impedance of 4 ohms, it offers 4 x 150 WRMS. If you lower the impedance to 2 ohms, the power increases to 4 x 270 WRMS. At just 1 ohm, the amplifier even delivers 4 x 425 WRMS, making it an excellent choice for applications that require high power. This capability ensures that your sound system provides powerful and clear audio output without compromising on sound quality.

Welche Technologien sind im GZPA Reference 4PURE-SQ integriert, um die Soundqualität zu verbessern?

The GZPA Reference 4PURE-SQ amplifier from Ground Zero integrates a variety of advanced technologies to enhance sound quality. It utilizes Class AB technology, known for its clear and robust sound. The symmetrical design of the device ensures that the audio signal is transmitted as unaltered as possible. Additionally, an extended BIAS control range allows for flexible adjustment of the sound input. The direct signal path minimizes signal loss, and the integration of exclusive high-quality components guarantees outstanding acoustic performance. This combination of technologies underscores the high-end level of the amplifier.

Wie beeinflussen rhodiumbeschichtete RCA Buchsen die Klangqualität des GZPA Reference 4PURE-SQ?

The rhodium-plated RCA jacks of the GZPA Reference 4PURE-SQ amplifier from Ground Zero offer significant advantages for sound quality. Rhodium is a precious metal that possesses extremely high conductivity while being very resistant to corrosion. These properties lead to excellent signal transmission that preserves critical sound details. The use of such high-quality jacks minimizes signal loss at connection points and prevents interference, contributing to a more precise and clearer sound image. For audiophiles, such technical details are crucial for the highest sound quality.

Welche Eigenschaften bietet der Kühlkörper im GZPA Reference 4PURE-SQ?

The exclusive heat sink of the GZPA Reference 4PURE-SQ is specially designed to efficiently manage heat dissipation, thereby optimally protecting the electronics. Adorned with an engraved Ground Zero logo, the heat sink offers not only a functional but also an aesthetic dimension. This sophisticated cooling mechanism ensures that the amplifier maintains a stable temperature under all operating conditions, which guarantees the longevity and reliability of the internal components. Especially during intensive use, effective cooling is essential to keep performance consistently at the highest level.

Welche Signalverarbeitungskapazitäten hat der GZPA Reference 4PURE-SQ durch seine Vorverstärkersektion?

The Ground Zero GZPA Reference 4PURE-SQ features a newly designed preamplifier section that provides essential signal processing capabilities. This section is designed to handle the input signal precisely and ensure enhanced sound quality across the entire frequency range of 5 Hz to 38 kHz. The special design improves the signal-to-noise ratio, increasing clarity even with subtle sounds and minimizing distortion. This technical finesse allows the amplifier to accurately reproduce even the finest audio details, making it the top choice for audio enthusiasts.

Welche Dimensionen hat der GZPA Reference 4PURE-SQ und wie ist die Installation durchführbar?

The GZPA Reference 4PURE-SQ amplifier from Ground Zero has dimensions of 236 mm in width, 590 mm in length, and 67.5 mm in height. These dimensions must be taken into account during installation in the vehicle to ensure that there is enough space available. The flat design allows for flexible mounting, often in the trunk or under the seats. When installing, it is important to ensure ventilation to avoid impairing the efficiency of the heat sink. These dimensions provide the opportunity to integrate the amplifier into many vehicle types without compromising functionality.

Wie beeinflusst die variable BIAS-Einstellung des GZPA Reference 4PURE-SQ die Klangcharakteristik?

The variable BIAS setting in the GZPA Reference 4PURE-SQ is a powerful feature that can significantly influence the sound characteristic. By adjusting the BIAS, the neutrality of the sound can be modified, which means you gain more control over the tonal balance and warmth of the music. This customization option is particularly valuable for audiophiles who prefer a specific sound profile. Depending on the chosen BIAS setting, the amplifier can exhibit more softness or pronounced dynamics, allowing for a personalized listening experience.

Welchen Vorteil bietet der Plexiglasboden des GZPA Reference 4PURE-SQ mit LED Beleuchtung?

The Plexiglas base of the GZPA Reference 4PURE-SQ amplifier from Ground Zero, combined with the LED lighting, not only offers a visually appealing design but also functional advantages. The lighting subtly highlights the internal components and allows for a quick check of hardware and connections. Especially in installations where the amplifier is visibly integrated, this thoughtful design aspect provides aesthetic added value. For enthusiasts who value both appearance and function, this amplifier is therefore an impressive element in the sound system.

Welche Frequenzwiedergabe deckt der GZPA Reference 4PURE-SQ ab?

The GZPA Reference 4PURE-SQ amplifier from Ground Zero offers a remarkably wide frequency response from 5 Hz to 38 kHz. This vast bandwidth ensures that the amplifier reproduces deep bass as powerfully as it does highs, while also being capable of accurately representing fine, subtle sound nuances in the midrange. This characteristic makes the amplifier ideal for audiophile applications where detail accuracy and sound transparency are paramount. Such comprehensive frequency reproduction allows you to enjoy almost any music track in all its glory.

Warum ist der symmetrische Aufbau des GZPA Reference 4PURE-SQ wichtig für die Klangqualität?

The symmetrical design of the GZPA Reference 4PURE-SQ amplifier plays a crucial role in optimizing sound quality. Symmetry in design minimizes electromagnetic interference and ensures that all components work together harmoniously. This means that the signal is affected as little as possible, which guarantees an authentic and clear sound transmission. This technical design is particularly important in high-end audio applications, as even the smallest interferences can significantly affect the audible sound. Thus, the symmetrical design is a key element for uncompromising audio quality.

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!
