PowerBass S-84 8" Dual 4-Ohm Subwoofer PowerBass S-Series woofers featuring a 4-layer wool/paper cone now sport a treated non-resonant finished, stamped steel basket that is custom tooled with distinctive X design. A 1.5” BASV voice coil former is used on the 8-inch, and a Large Roll foam surround for precise linear movement of the cone, which equals loud bass. The S Series subwoofers are well-suited for small sealed or ported enclosures and use dual 4-ohm and single 4-ohm voice coils for multiple bass applications. Now more than ever, S-Series woofers provide lots of value without sacrificing hard-hitting performance.
