PowerBass S-10TD Thin Mount 10" 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.
