Ground Zero's massive limited edition 30th anniversary subwoofer is finally here! We only got 50 of these, so be quick to get yours!

This Klippel optimized piece encapsulates the know-how and expertise accumulated during Ground Zero's 30-year journey, which makes this element a true work of art: a black painted open cast frame, a well-ventilated sturdy magnet, gold-plated pressure connectors, a pressed paper cone, a wide top suspension with gold-colored stitching and all this is crowned by a carbon fiber dust cup with a gold Ground Zero logo.

This subwoofer doesn't leave you cold either based on the technical specifications: FS 26.5 Hz, 1500W continuous power handling, 45mm Xmax!!! and 3″ voice coil.

It is recommended to install the element in a 90L* reflex enclosure.
