Frequent questions about Competition GZCK 250XSPL

Welche Vorteile bietet die 50 mm CCAW Schwingspule des Competition GZCK 250XSPL?

The 50 mm CCAW voice coil of the Competition GZCK 250XSPL from Ground Zero ensures excellent heat dissipation and high load capacity. This design allows for a higher power handling of up to 200 Watts RMS, providing stable sound reproduction even at high volumes. The use of CCAW (Copper Clad Aluminum Wire) reduces the weight of the voice coil, improving efficiency and performance. This helps to achieve an efficiency of 94 dB, requiring less power to achieve loud and clear sound reproduction.

Wie wirkt sich die faserverstärkte Papiermembran auf die Klangqualität aus?

The fiber-reinforced paper membrane of the Competition GZCK 250XSPL is crucial for sound quality. It combines the low weight and stiffness of paper with additional fibers for reinforcement, resulting in stable and precise sound reproduction. This construction minimizes distortion and allows for detailed and clear sound across the entire frequency range of 50 Hz to 6 kHz. Additionally, the membrane contributes to the high sensitivity of 94 dB, which means that the speaker operates efficiently even at low power while still delivering powerful sound.

Welche Rolle spielt die Langhub-Schaumstoffsicke bei der Performance?

The long-stroke foam surround plays a crucial role in the performance of the Competition GZCK 250XSPL. It allows for greater membrane excursions, which is particularly important at low frequencies. This enables the speaker to reproduce deep bass accurately and without distortion. Additionally, the foam surround provides high damping, allowing for resonance-free oscillation of the membrane. This improves overall sound quality and reduces distortion while ensuring a stable and clean sound at high volumes. This design supports a power handling of 200 watts RMS.

Wie beeinflusst der resonanzarme Stahlkorb die Klangwiedergabe?

The resonance-optimized steel basket in the design of the Competition GZCK 250XSPL significantly contributes to the stability and clarity of sound reproduction. By minimizing resonances, the basket prevents these vibrations from negatively affecting sound quality. This is particularly important for maintaining the precision and purity of the sound and reducing distortions. The robust construction of the steel basket also ensures a firm anchoring of the entire speaker unit, which eliminates further unwanted vibrations and thus guarantees a clear, uncolored sound.

Ist der Competition GZCK 250XSPL mit den meisten Fahrzeugen kompatibel?

The Competition GZCK 250XSPL has a nominal diameter of 250 mm (10 inches), making it compatible with many standard speaker cutouts. It is important to check the exact dimensions before installation to ensure that the speaker fits into the existing speaker opening. For specific vehicle compatibility, the installation depth and available space in the vehicle must be considered. The impedance of 4 ohms is suitable for most common audio systems, but should also be checked before installation. If adjustments are necessary, they usually involve some effort.

Was umfasst der Frequenzbereich des Competition GZCK 250XSPL?

The frequency range of the Competition GZCK 250XSPL extends from 50 Hz to 6 kHz, covering a wide range of tones. At 50 Hz, the speaker begins to reproduce deep bass clearly and powerfully, which is essential for a mid-bass driver. The upper limit of 6 kHz allows for precise control of higher frequencies as well. This broad frequency coverage ensures that the speaker can be used for bass, midrange, and partially for treble applications, depending on the system configuration in the car. Thus, the speaker offers a lot of flexibility in application variety for various music genres.

Wie wirkt sich die Gesamtimpedanz von 4 Ohm aus?

The impedance of 4 ohms of the Competition GZCK 250XSPL is a typical value for car audio speakers and directly affects compatibility with most amplifier systems. A lower impedance allows for higher current draw, which often leads to higher volume. This offers advantages in terms of efficiency and overall compatibility with most car audio systems. However, it is important to ensure that the amplifier used is compatible with this impedance to guarantee full power without the risk of overheating or damage. The 4-ohm impedance is ideal for strong, dynamic bass and midrange reproduction.

Welche Belastbarkeit hat der Competition GZCK 250XSPL?

The Competition GZCK 250XSPL has a power handling capacity of 200 watts RMS, making it an ideal candidate for high-performance audio applications. RMS or Root Mean Square is a measure of how much continuous power the speaker can handle over an extended period without damage. This high power handling ensures that the speaker plays cleanly and without distortion even at high volumes. This allows for powerful sound experiences without the risk of overload. This is a crucial advantage, especially for music lovers who appreciate dynamic sound output.

Welchen Wirkungsgrad hat der Competition GZCK 250XSPL und was bedeutet das?

With an efficiency of 94 dB, the Competition GZCK 250XSPL is among the more efficient speakers in its class. The efficiency indicates how much sound pressure the speaker generates at a certain power level. A higher efficiency means that less power is needed to achieve a certain volume, allowing for efficient operation of the connected amplifiers. For the user, this means: The speaker can also be operated with less powerful amplifiers and still delivers an impressive sound. This is particularly advantageous in applications where energy efficiency is important.

Gibt es optionales Zubehör für den Competition GZCK 250XSPL?

Yes, a specially designed protective grille (GZCK 250XSPL Grill) is available separately for the Competition GZCK 250XSPL. This protective grille provides additional physical protection for the speaker membrane against damage from external influences such as impacts or mechanical forces. It is particularly useful in environments where the speaker is placed unprotected, for example in the trunk. The protective grille does not affect sound quality and is easy to install. This accessory helps improve the longevity of the speaker and ensures that its performance remains optimal over a long period.

Super guter Subwoofer

Super Subwoofer mit extrem tiefem Bass. Die Kabel sind dick und hochwertig verarbeitet. Es gibt nichts zu beanstanden. Absolut empfehlenswert.

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 .

X-10 v3 d2

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!
