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 Ground Zero GZUM 55SQ is a compact 55-mm midrange speaker from the Uranium series, designed for high-end car audio systems with a particular focus on sound quality. Thanks to its coated silk dome, the midrange driver combines detailed reproduction with a pleasantly balanced sound character.

A high-performance neodymium magnet is used as the driver. Combined with the generously sized 55-mm copper voice coil, this design enables a power handling capacity of 90 watts RMS or 150 watts maximum. With a usable frequency range of 500 Hz to 11 kHz, the GZUM 55SQ is particularly well-suited for high-quality multi-way and active loudspeaker systems.

The shallow installation depth of just 33 mm makes it easy to integrate the unit into various mounting positions within the vehicle. The package also includes a hexagonal protective grille in the signature Ground Zero design
