The Aquarian DEEP VINTAGE SUPERKICK brings Old School, "deep” sounding heads to contemporary drums with no loss of resonance. Aquarian's multi-ply vacuum molding process. eliminates “dead air” spots and adds depth and durability to bonding of these 2x10mil plies. The patented Aquarian Floating Muffle Ring helps to increase low-end punch and definition. More than cosmetic, the slightly thicker vintage coating slows the vibration of the head and results in a lower, warmer tone with a softer feel and a classic look. The DEEP VINTAGE two-ply models bring the inspired sound of traditional calfskin heads to the modern drum and drummer, but with better performance results.
