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 GZNW 38XMAX-II was developed for extreme subwoofer applications and is aimed at ambitious car audio enthusiasts who expect uncompromising power handling and enormous excursion. Its sophisticated design—featuring an aluminum cone, a flow-optimized cast aluminum basket, and a specially engineered long-throw surround—ensures high mechanical strength and precise control even at very high power levels.

Thanks to Klippel® optimization, the subwoofer operates with exceptional linearity across its entire excursion range and delivers clean, controlled bass even under heavy load. The generously sized 75-mm aluminum voice coil, the robust 7-layer suspension, and solid push terminals make the GZNW 38XMAX-II the ideal choice for high-performance daily-driver and SPL-oriented systems. When paired with a high-power amplifier, the subwoofer unleashes its full potential, delivering impressive low-frequency extension and enormous sound pressure reserves.
