High-power horn tweeter with heavy-duty 25 mm silk dome from Ground Zero

The Ground Zero tweeter incorporates a heavy-duty 25 mm silk dome tweeter. This special silk dome tweeter enhances the sound by delivering clear and detailed highs. Silk as a material enables a smooth reproduction that harder membrane materials often cannot achieve. Unusual in the high-power segment, the silk dome tweeter also offers high thermal stability – crucial for long sessions at high volume. The material coating gives the tweeter additional robustness, which is advantageous in the car hi-fi segment. A slightly harder material choice could result in a loss of the characteristic sound definition.

Neodymium magnet and ferrofluid cooling for maximum efficiency and sound fidelity

The Ground Zero Competition GZCT 25SQL utilizes a neodymium magnet. This magnetic structure ensures high efficiency with low weight. Neodymium is known for generating a very strong magnetic field, which contributes to increased efficiency. This design is complemented by ferrofluid cooling, which ensures the thermal stability of the voice coil. Ferrofluid contributes to reducing mechanical wear, extending the lifespan of the tweeter, and guaranteeing consistently high audio performance. A greater cooling requirement would require more powerful cooling through larger passive heatsinks, which this design significantly avoided.

Optimized sound distribution through 60° wave guide alignment and cast aluminum housing

The Ground Zero tweeter's cast aluminum housing is not only robust but also ensures excellent acoustic properties. The 60° waveguide design promotes precise sound dispersion. This special alignment counteracts irregularities in sound dispersion typically found in conventional designs. This creates an extremely realistic sound experience for this midrange component. Without this waveguide, even sound distribution in larger rooms would be difficult. This significantly influences the level of detail expected from tonally sophisticated products.

Impedance of 4 ohms ensures optimal system integration and sound quality

With an impedance of 4 ohms, the Ground Zero tweeter integrates seamlessly into existing sound systems. This electrical property determines how much current the tweeter can draw from an amplifier. 4 ohms is widely used in the car hi-fi industry and ensures a good balance between volume and sound clarity. A higher resistance could impair the system's efficiency, while a lower resistance could potentially overload the amplifier.

25 mm voice coil and its influence on the sound of the Ground Zero Competition GZCT 25SQL

The 25 mm voice coil of the Ground Zero tweeter plays a pivotal role in converting electrical signals into mechanical motion. This dimension enables precise dome drive and ensures coherent sound reproduction under high loads. Combined with the silk dome, the sound is reproduced with exceptional detail, generating precise highs in tonally complex pieces. A larger voice coil could lead to inertia and a loss of dynamics, whereas a smaller one could reduce power handling.

Solder connections and high processing heat of the Ground Zero tweeter

The Ground Zero tweeter's solder connections offer a reliable method for wiring and integration into existing audio systems. This method reduces contact problems and ensures clean signal flow over time. Considering car hi-fi components, which are often used in harsh conditions, this processing method ensures optimized operational stability. Terminal blocks would be a better alternative, but solder connections are more durable in practice and are not significantly affected by high temperatures.

Efficient dimensioning and installation dimensions for precise adaptability

With a mounting diameter of 50 mm and a mounting depth of just 36 mm, the Ground Zero tweeter is characterized by its compact dimensions. This dimension makes it ideal for use in models with limited space and offers installation flexibility.
