Wiring wizard & port computer

Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!

Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

The Ground Zero GZCT 25SQL is a high-performance 25-mm tweeter from the Competition Series that combines high power handling with balanced and detailed high-frequency reproduction. This makes it particularly well-suited for high-end car audio systems that require both sound quality and the ability to play at high volumes.

A coated silk dome is used as the diaphragm. Combined with the 25-mm voice coil and the powerful neodymium driver, it enables precise and dynamic reproduction in the high-frequency range. The voice coil is cooled by ferrofluid, which ensures that the tweeter can withstand thermal stress even under heavy load.

A 60° aluminum wave guide ensures controlled sound dispersion. The sturdy cast aluminum housing also provides a robust foundation for long-term installation in the vehicle.

With a sensitivity of 93 dB, the GZCT 25SQL operates very efficiently. Its power handling capacity is 100 watts RMS or 150 watts maximum when used with a suitable high-pass filter. The usable frequency range extends from 3,000 Hz to 22,000 Hz.

With its combination of high power handling, an efficient neodymium driver, and a silk dome, the GZCT 25SQL is an attractive choice for performance-oriented 2-way and multi-way car audio systems, as well as custom SQL and competition installations.
