The Rockford Fosgate Power T1D212 / T1D412 dual 2-ohm and dual 4-ohm 12" (30cm) subwoofers are based on innovative new technologies from Rockford Fosgate. They feature patented VAST technology, which increases the surface area of the diaphragm by up to 25%, so the T1D212 andT1D412look like a much larger woofer compared to the previous model. The new FlexFit basket not only looks good, but also provides extreme flexibility for extreme installations.
