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 GZRT 25SQ is a compact 25-mm tweeter from the RADIOACTIVE series, designed to deliver detailed and clean high-frequency reproduction for car audio systems. Its coated silk dome combines high-resolution sound reproduction with a pleasantly balanced tonal character, making it particularly well-suited for sound-oriented speaker systems.

The driver features a high-performance, vented neodymium magnet system. In combination with the ferrofluid cooling of the voice coil, the GZRT 25SQ is rated for an RMS power handling capacity of 70 watts and a maximum power handling capacity of 110 watts. The tweeter achieves a sensitivity of 89 dB at a nominal impedance of 4 ohms.

Another advantage is its compact design. With an installation depth of just 16 mm, the tweeter can be integrated even into installation locations with limited space. The plastic housing, including the mounting frame, allows for seamless integration into custom-built car audio systems.

The recommended frequency response ranges from 2,500 Hz to 24 kHz. This makes the GZRT 25SQ suitable for both traditional passive multi-way systems and active or DSP-controlled systems. For the specified power handling capacity, GROUND ZERO recommends a high-pass filter at 2,500 Hz with a slope of 12 dB/octave.
