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 STEG QK3 is a high-quality 3" midrange driver from the QK high-end speaker series, designed specifically for demanding car audio systems. With its precise sound reproduction, high level of detail, and natural vocal rendering, this speaker is ideal for high-quality 3-way systems and fully active DSP installations.
The specially damped paper diaphragm ensures balanced and detailed reproduction of the midrange. The sturdy, vented die-cast aluminum basket reduces unwanted resonances, while the powerful neodymium magnet drive and precision-engineered components enable controlled diaphragm movement.
Thanks to its compact design with a mounting depth of just 43 mm, the STEG QK3 can be flexibly integrated into dashboards, A-pillars, or custom-made speaker mounts. The included black aluminum trim rings and protective grilles also ensure a high-quality and visually appealing installation.
