Ground Zero USA is excited to introduce our two newest Radioactive models.

August 12, 2020 -- Now shipping is the GZRB 20SPL and the GZRW 8XSPL. 

Recently announced, and now available, the GZRW 8XSPL (MAP $229.99) is the little brother to our wildly successful Hydrogen 8-inch subwoofer. This driver is a high-quality SPL subwoofer that utilizes a reinforced paper cone with a long stroke compound surround, dual 2-ohm 50mm/2” copper voice coils, and is designed to run on 500w RMS. This driver is best suited for vented applications, and we have you covered with that also.  

The GZRB 20SPL  (MAP $379.99) is a custom tailored preloaded vented enclosure with grill specifically for the GZRW 8XSPL (included).
