Frequent questions about GZCT 25M-SPL

Welche Leistungsdaten bietet der GZCT 25M-SPL?

The GZCT 25M-SPL from Ground Zero boasts impressive performance specifications. It is equipped with a dome tweeter and a 25 mm Mylar dome with a neodymium magnet. The power handling is 70 watts RMS and up to 100 watts maximum power, making it particularly powerful. With a frequency response of 3000 Hz to 20 kHz, it covers a wide range. Additionally, it offers an impedance of 4 ohms and an efficiency of 84 dB. The crossover frequency is at 5500 Hz thanks to the integrated 12 dB/oct high-pass filter.

Wie wird der GZCT 25M-SPL installiert?

The installation of the GZCT 25M-SPL tweeter from Ground Zero is easy thanks to its practical design. With a mounting diameter of 48 mm and a mounting depth of only 16 mm, it fits into many audio systems. The installation usually takes place at a suitable location in the vehicle interior, with the mounting bracket being useful. Pay attention to the correct wiring with the included high-pass filter to optimally utilize the specified crossover frequency of 5500 Hz. Proper placement ensures the best sound quality.

Warum ist Ferrofluid-Kühlung im GZCT 25M-SPL wichtig?

Ferrofluid cooling is an advanced feature of the GZCT 25M-SPL from Ground Zero. This technology enhances the heat dissipation of the 25 mm voice coil and contributes to the longevity and stability of the device. Especially at high power, ferrofluid prevents the tweeter from overheating, positively affecting sound performance. With reduced heat generation, distortion remains minimal, and sound quality is preserved even at higher volumes. It is a crucial factor for consistent audio quality and reliability.

Welche technischen Merkmale hat der Mylar-Kalottenhochtöner des GZCT 25M-SPL?

The Mylar dome tweeter in the GZCT 25M-SPL from Ground Zero offers a variety of technical features. The dome diameter is 25 mm, making it compact yet powerful. The use of a neodymium magnet enables a strong magnetic force even at a small size, which contributes to improved sound performance. The integrated high-pass filter operates with a crossover frequency of 5500 Hz, ensuring precise frequency separation. Mylar as a diaphragm material provides high durability and optimal acoustic properties.

Wie funktioniert der Hochpass-Filter im GZCT 25M-SPL?

The high-pass filter included in the GZCT 25M-SPL from Ground Zero has a significant impact on sound quality. It is designed with a 12 dB/octave transmission that ensures seamless integration of the tweeter into the audio system. The main function of this filter is to block low frequencies, effectively enhancing the high-frequency range. With a crossover frequency of 5500 Hz, the filter ensures that only the desired high frequencies reach the tweeter, significantly improving sound purity and clarity while reducing distortion.

In welchem Frequenzbereich arbeitet der GZCT 25M-SPL?

The frequency range of the GZCT 25M-SPL from Ground Zero extends from 3000 Hz to 20 kHz, making it particularly versatile for various music genres. This range allows for the reproduction of clear and precise highs, which are crucial for the fidelity and character of the music. The precise tuning by the Mylar dome tweeter ensures that even at high frequencies, there is minimal distortion. This range is ideal for anyone who places an emphasis on high-quality audio reproduction in the high-frequency range.

Wie verbessert die Verwendung eines Neodym-Magneten die Klangperformance des GZCT 25M-SPL?

The neodymium magnet in the GZCT 25M-SPL from Ground Zero is a key element for the outstanding sound performance of the tweeter. Thanks to its small size and high power, this magnet provides a strong and consistent magnetic force on the Mylar dome. This leads to more efficient movement, allowing the tweeter to respond quickly to signals and offer more precise sound characteristics. Neodymium magnets are known for their stability and strong performance, making the GZCT 25M-SPL ideal for users who love clear and powerful sounds.

Was ist die Rolle der 25 mm Schwingspule im GZCT 25M-SPL?

The 25 mm voice coil in the GZCT 25M-SPL from Ground Zero plays a central role in the impedance tuning and influencing the sound quality. It ensures the direct conversion of electrical signals into mechanical movements of the Mylar diaphragm, which ultimately produce audible sounds. A larger voice coil, like this 25 mm variant, offers improved heat resistance and greater stability at high volumes. These characteristics ensure that the tweeter delivers consistent and high-quality audio performance even under extensive use.

Welche Abmessungen hat der GZCT 25M-SPL?

The GZCT 25M-SPL from Ground Zero has specific dimensions that facilitate its installation. The installation diameter is 48 mm, and the installation depth is only 16 mm, making it flexible and compatible with various vehicle models. This compact design allows the tweeter to be placed in different locations within the car audio system without requiring much space. The small dimensions are particularly advantageous when you want to implement a high-quality sound system in your vehicle with limited space.

Wie wirkt sich die Impedanz von 4 Ohm auf den GZCT 25M-SPL aus?

The impedance of 4 Ohms of the GZCT 25M-SPL from Ground Zero has a decisive influence on power consumption and compatibility with amplifiers. A low-impedance speaker like this draws more power, which promotes a strong audio signal and ensures dynamic sound reproduction. This is particularly useful when powerful and energetic sound dynamics are desired. However, ensuring compatibility with amplifiers designed for low-impedance loads is important to fully exploit the speaker's potential without overloading the audio setup.

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!
