PowerBass S-1204D 12" Dual 4-Ohm Subwoofer By adding a tough wide roll rubber surround and 2-inch vented voice coil, PowerBass were able to develop a woofer that has the ability to play loud in small places. The PowerBass Thin Woofer makes true bass a reality. Starting with our proprietary poly-carbonate/glass fiber composite frame, PowerBass built a basket that is stronger than steel and lighter than cast aluminum. The unique one piece cone is another break through in woofer technology, more durable and stiffer then paper, this injected molded cone is able to withstand the abuse that comes from delivering deep bass in a small enclosure.
