Ground Zero GZRW 8XSPL

A few years ago, the first Klippel-optimized Radioactive subwoofer saw the light of day. And since then, thanks to their reliability and performance, they have been the best-selling subwoofers on the market. Now it’s the turn of the next generation where the details have been filed even better! The HighRoll upper suspension is double-stitched to a reinforced paper cone. A 2″ voice coil wound from copper wire, which is effectively cooled. A good-sized magnet in a sturdy steel sheet frame keeps the package firmly together. The voice coil conductors running over the Polycot under-suspension are well dimensioned. For attaching the speaker cable, there are spring-loaded connectors that can accommodate up to 8mmq cables. The spring-loaded connector is very sturdy and does not loosen even during vibration. The elements are suitable for many types of and multi-sized housings. Once again, Ground Zero sets a model for others on how to make the most powerful subwoofers in the mid-price category.
