The renewed edition of the legendary GZNW15 subbar is now here!
The product development of the new XMAXX collection was challenging, because the predecessor was ahead of its time with its mega-long trajectories.

The XMAXX model includes the high roll suspension developed further from Ground Zero's SPL upper suspension, which keeps its shape even when played from spike to spike.
There are many similar elements on the market, but often these lose their control at maximum ranges of motion, this does not happen with these.

Due to the increased range of motion, many internal changes have also been made to the motor, so that the air flow remains controlled and the voice coil gets the necessary cooling.
This is a common problem in similar elements, Ground Zero has also realized it, thus the design of the engine inside is unique.
We claim that XMAXX elements are the only elements of this style with which you can enjoy air movement with excellent sound quality in the entire 10-70hz band.
That is, with this element you can also play frequencies above 40hz, which is usually an impossibility in elements with 80-120mm mechanical movement.
(At high frequencies, turbulence forms in a normal motor and the coil overheats immediately)

XMAXX is the world's first Klippel-optimized subwoofer with a mega-long range of motion.
All components are in balance with each other.
