This Sony XS-L121P5's unique five sided polypropylene cone not only looks cool but is stiffer than conventional round cones for lower distortion and higher power handling. The solid construction P5 center cap adds additional strength to the cone assembly and looks cool too! The unique foamed rubber surround with stroke stabilizers and double damper suspension ensures distortion free bass response, even at "wake up the entire neighborhood" volume levels. The P5's unique basket design allows the woofer to mounts in regular round woofer holes.
