The Powersonic Bass Drumheads gives the drummer controlled mid range and low end for the most powerful bass drum sound right out of the box. These heads are constructed of 2-ply, 7mm Mylar with two specifically placed internal subsonic dampening rings with External Snap-on Dampening System technology. The two mounted 3/4" internal dampening rings enhance low end without fixating trays or hard backed dampening materials to the drumhead.
The unique patent pending ESDS system employs snaps mounted directly to the drumhead to eliminate the possibility of vibration. This allows you to easily customize your muffling, feel and sustain for different playing situations by "snapping" the strategically placed weighted pillow to the drumhead. Also included is the Falam Slam for added attack and durability.
