Frequent questions about Competition GZCM 8.0SPL

Was sind die Hauptmerkmale des Ground Zero Competition GZCM 8.0SPL?

The Ground Zero Competition GZCM 8.0SPL is an 8-inch (20 cm) mid-bass driver with a fiber-reinforced paper cone. Equipped with a 38 mm CCAW voice coil and a resonance-optimized steel basket, it offers high performance. The power handling is 150 W RMS and a maximum of 400 W, while the efficiency is at 95 dB. A frequency response of 140 Hz to 10 kHz ensures a wide sound spectrum. The speaker has an impedance of 4 Ohms, indicating a specific adaptation for common amplifiers. The FERRITE magnet and protective grille make it robust and reliable in application.

Wie ist der Frequenzgang des Ground Zero Competition GZCM 8.0SPL?

The frequency response of the Ground Zero Competition GZCM 8.0SPL ranges from 140 Hz to 10 kHz. This means that the speaker can cover deep mids to high frequencies, making it ideal for those seeking clarity in the midrange. With a frequency range that covers a large part of the audible spectrum, the speaker is well-suited for reproducing music pieces that contain both powerful bass and sharp highs. This demonstrates the versatility of the speaker, especially in reproducing complex sound structures.

Welche Abmessungen hat der Competition GZCM 8.0SPL für den Einbau?

The Ground Zero Competition GZCM 8.0SPL has a mounting diameter of 182 mm and a mounting depth of 87 mm, as well as a maximum mounting depth of 92 mm. These compact dimensions allow for flexible installation in various vehicle types, provided there is enough space in the installation cavity. Especially in custom car installations, it is important to keep the depth in mind to ensure that the speaker can be properly mounted while maintaining its excellent sound quality. The dimensions are crucial for a hassle-free installation.

Welche Materialien werden beim Ground Zero Competition GZCM 8.0SPL verwendet?

The Competition GZCM 8.0SPL uses a fiber-reinforced paper membrane that ensures a balanced sound image by minimizing resonances. The steel basket of the speaker is low-resonance to prevent vibrations and distortions, while the ferrite magnet provides the necessary magnetic force to efficiently control the movement of the voice coil. The short CCAW voice coil helps to reduce weight while maintaining efficiency. This combination of materials makes the speaker not only powerful but also robust and durable.

Wie ist die Belastbarkeit des Ground Zero Competition GZCM 8.0SPL?

The Ground Zero Competition GZCM 8.0SPL has an RMS power handling of 150 watts and achieves a maximum power handling of 400 watts. These values indicate that the speaker can deliver strong performance without distortion when operated within its rated values. Especially at high volume, it is important to pay attention to the power handling to ensure the longevity and sound integrity of the speaker. These performance characteristics make it ideal for use in demanding audiophile setups.

Welche Schwingspule wird im Ground Zero Competition GZCM 8.0SPL verwendet?

In the Ground Zero Competition GZCM 8.0SPL, a 38 mm short CCAW voice coil (Copper Clad Aluminium Wire) is used. This type of voice coil offers the advantage of lower weight compared to conventional copper wire coils, without losing conductivity or stability. A lighter voice coil allows for a faster response to input signals, resulting in improved sound accuracy. The precise manufacturing and material of the voice coil significantly contribute to enhancing the dynamic performance of the speaker.

Welche Rolle spielt der Ferritmagnet im Ground Zero Competition GZCM 8.0SPL?

The ferrite magnet in the Ground Zero Competition GZCM 8.0SPL is central to the function of the speaker, as it generates the magnetic field that influences the voice coil. It ensures that the voice coil is moved in the correct direction and that the diaphragm can produce sound. Ferrite magnets are known for their durability and resistance to demagnetization. This keeps the sound quality of the speaker consistent over a long period. This type of magnet also ensures the necessary efficiency and reliability during intense use.

Ist der Ground Zero Competition GZCM 8.0SPL mit einem Schutzgitter ausgestattet?

Yes, the Ground Zero Competition GZCM 8.0SPL comes standard with a protective grille. The protective grille provides an additional layer of protection that shields the sensitive diaphragm from mechanical damage and foreign objects. Especially in environments where the speaker may be exposed to direct contact with objects, the protective grille is invaluable. It helps to extend the lifespan of the speaker and maintain sound quality in any environment.

Wie hoch ist der Wirkungsgrad des Ground Zero Competition GZCM 8.0SPL?

The efficiency of the Ground Zero Competition GZCM 8.0SPL is 95 dB. This high efficiency means that the speaker is capable of achieving a high sound pressure level with low energy input, which is particularly important when maximizing speaker performance in low-watt environments. A higher efficiency leads to better utilization of the provided power, resulting in a louder and clearer sound image. This makes it especially attractive for high-quality sound installations where efficiency and volume play a significant role.

Welche Resonanzfrequenz besitzt der Ground Zero Competition GZCM 8.0SPL?

The resonance frequency of the Ground Zero Competition GZCM 8.0SPL is 91 Hz. This frequency describes the point at which the speaker vibrates at its natural frequency when no external forces are acting. A lower resonance frequency allows for stronger bass reproduction, which is ideal for a mid-bass driver, as it fills the gaps between standard midrange and bass drivers. Knowing the resonance frequency is crucial for proper tuning in closed or vented enclosures to optimize sound response.

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!
