π-b is a compact but strong subwoofer with 2 PCs of high-performance 12" neodymium LF drivers. As the result of our decades of high power output loudspeaker development, the subwoofer enables extra high continuous rated power output by a brand new design. Improved cooling enhances the subwoofer's reliability as well as durability. The cabinet is built with high-quality multi-layer plywood.
