News – GZHW XSPL Subwoofer
GROUND ZERO improved the performance of the HYDROGEN series SPL subwoofers. The new XSPL generation comes with a completely new surround, developed for high excursion and outrageous SPL. Furthermore, the line-up includes not only the double 1-ohm models but double 2-ohms voice coil versions, too.
