The Aquarian Superkick III is a coated single-ply medium-weight bass drumhead with a power dot in the center for added reinforcement. The Superkick III bass drumhead produces a low-end well-defined punchy sound due to Aquarian s patented Floating Muffling System which is a narrow felt muffle ring attached to the backside of the drumhead. Safe-T-Loc hoop This hoop system prevents slippage inside the hoop so that the head does not de-tune during a performance and will not pull out. Tuning is consistent and the head stays in tune. Sound Curve Collar Design This design allows the drumhead to seat perfectly on the bearing edge. No wrinkles even with loose tuning. It conforms instantly to any shell design and makes tuning fast easy and more accurate. Triple Locking System This unique system provides drummers with previously unheard of advantages in resonance and playability. First holes are punched in the bottom of a U shaped channel which has been formed in the drumhead. These holes allow the epoxy to flow into the Safe-T-Loc channel. Second the T-Ribs that form the Safe-T-Loc channel prevent the epoxy and the drumhead from slipping and pulling away from the hoop. Lastly the Locking Shoulder acts as a stop to ensure the correct collar height for the drumhead.
