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