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.Â
