motoh-end system consisting of a 165 mm woofer and a 28 mm dome tweeter.

The woofer has a phase plug in the center. Acoustically, the phase plug ensures that the sound emitted by the cone is not reflected at the pole core. In this case, phase shifting can lead to cancellations that are noticeable as a dip in the midrange.

A passive crossover is included with the speaker system (not with AC active version). The complete Gladen Zero Pro speaker system is designed and built in Germany.

For better alignment or mounting of the tweeter the optional Gladen PODs  an be used.
