Frequent questions about Competition GZCM 10.0SPL

Welche Leistung bietet der Ground Zero Competition GZCM 10.0SPL?

The Ground Zero Competition GZCM 10.0SPL impresses with an enormous RMS power of 200 watts and a maximum power capacity of 500 watts. These specifications make it a high-power midrange speaker capable of delivering powerful and clear sounds, even at high volumes. This means you can increase the volume without hesitation to enjoy every detail of your favorite music. Combined with its high efficiency of 96 dB, the speaker ensures that energy is used efficiently to provide an outstanding audio experience.

Welche Materialien werden für den Ground Zero Competition GZCM 10.0SPL verwendet?

The Ground Zero Competition GZCM 10.0SPL speaker uses a fiber-reinforced paper diaphragm that offers both strength and flexibility. This construction allows for precise and clear sound reproduction. The 50 mm CCAW voice coil further contributes to the excellent performance of the speaker by ensuring a fast and efficient response to audio signals. In combination with the ferrite magnet and a resonance-free steel basket, an excellent acoustic performance is achieved, characterized by clear highs and precise mids, while the dual cone paper dust cap contributes to the sound performance.

Wie beeinflusst die Resonanzfrequenz des Ground Zero Competition GZCM 10.0SPL die Klangqualität?

The resonance frequency (Fs) of the Ground Zero Competition GZCM 10.0SPL is 76 Hz. This frequency is crucial as it describes the speaker's inherent behavior in relation to its vibrations. A lower resonance frequency means that the speaker is capable of reproducing deeper bass tones without losing clarity. This ensures a balanced and complete sound reproduction, where both low and high frequencies are rendered accurately. Especially if you enjoy listening to music at high volumes, you will benefit from this acoustic versatility at any volume.

Welche Abmessungen hat der Ground Zero Competition GZCM 10.0SPL und wie erfolgt die Installation?

The Ground Zero Competition GZCM 10.0SPL has an outer diameter of 250 mm and a mounting opening of 231 mm, with a mounting depth of 98 mm. These dimensions must be taken into account during installation to ensure that the speaker can be installed correctly. The installation must take place in a housing or environment that accommodates these dimensions. The speaker comes with a protective grille, which not only provides additional protection but is also helpful for placement within vehicles to ensure the longevity of the speaker.

Welche Frequenzbereiche kann der Ground Zero Competition GZCM 10.0SPL abdecken?

The frequency response of the Ground Zero Competition GZCM 10.0SPL ranges from 100 Hz to 10 kHz. With this wide frequency spectrum, the speaker effectively covers both low and high tones. This is particularly relevant in more complex music genres that require full sound coverage. The ability to cover such frequency ranges makes the speaker extremely versatile and powerful in various audio compositions. The fiber-reinforced paper diaphragm and the dual cone paper dust cap contribute to this by providing clear and precise audio reproduction across the entire frequency range.

Wie hoch ist der Wirkungsgrad des Ground Zero Competition GZCM 10.0SPL?

The efficiency of the Ground Zero Competition GZCM 10.0SPL is 96 dB, indicating a high efficiency in converting electrical energy into acoustic energy. A higher efficiency means that the speaker produces a higher sound output at the same electrical power. This is particularly advantageous in applications where loud and clear sound is required without significant energy expenditure. This feature makes the speaker ideal for use in vehicles and other environments where efficiency and performance must go hand in hand to achieve optimal sound results.

Was macht die faserverstärkte Papiermembran des GZCM 10.0SPL besonders?

The fiber-reinforced paper membrane in the Ground Zero Competition GZCM 10.0SPL combines the best properties of strength and flexibility to ensure exceptional sound quality. This construction allows the speaker to produce precise vibrations necessary for the reproduction of clear and sharp tones. The reinforcement by fibers increases the robustness of the membrane, leading to better performance, especially at high volumes or intense bass frequencies. This design ensures that the speaker is not only durable but also delivers consistent sound quality over extended periods.

Welche Rolle spielt der Ferrit Magnet im Ground Zero GZCM 10.0SPL?

In the Ground Zero Competition GZCM 10.0SPL, the ferrite magnet provides a powerful magnetic voice coil that controls the movement of the voice coil and produces optimal sound. Ferrite magnets are known for their stability and reliability, which means that the speaker can deliver consistent performance even under intense use. The combination of magnet strength and the design of the speaker promotes even and precise reproduction of all audio signals. These characteristics are crucial for ensuring high-quality audio playback, making it well-suited for reproducing both mid and bass frequencies.

Welche Tipps gibt es für die Platzierung des Ground Zero Competition GZCM 10.0SPL?

When placing the Ground Zero Competition GZCM 10.0SPL, the specific dimensions of the speaker should be taken into account, as the outer diameter is 250 mm and the installation depth is 98 mm. To achieve the best possible performance, the speaker should be mounted in an area that accommodates these dimensions while also providing an optimal vibration-free environment. The resonance-optimized steel basket already ensures part of the structural stability; however, it is important to mount the speaker securely to minimize unwanted influences on the sound. This ensures that the speaker can fully unleash its technical performance.

Wie beeinflusst der resonanzarme Stahlkorb die Klangqualität des GZCM 10.0SPL?

The resonance-optimized steel basket of the Ground Zero Competition GZCM 10.0SPL directly affects the acoustic integrity of the speaker by reducing vibrations and resonances that could impair sound quality. Its robust design promotes a stable and uniform vibrational movement of the speaker diaphragm, resulting in a clean, uncolored sound image. This feature is particularly advantageous at medium to high volumes, as the sound is maintained without distortion or loss of quality. Additionally, the steel basket enhances the durability of the speaker by serving as a protective structure, ensuring that the speaker remains consistently high-performing even under intense use.

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!
