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.
