Decade’s 6-ply/5.4mm all Maple shell is what sets it apart from the other players in the field. The final product of ten years of process and material refinement, each cross-laminated ply incorporates Pearl’s proprietary Superior Shell Technology. The resulting thin (but powerfully strong) shell reacts quickly to the stroke, producing beautifully resonant highs and thundering lows.
Pearl’s Superior Shell Technology utilizes a proprietary technique for achieving the ultimate air chamber. It begins with select woods chosen for their unique acoustic attributes, milled to precise thickness with overlapping scarf joint seams, for a perfect air-tight fit. The wood plies are saturated with Pearl’s proprietary “AcoustiGlue” that permeates every pore and dries to the exact consistency of the wood for optimum resonance. Finally, the plies are formed in high-temperature molds with 1000 PSI of hydraulic pressure to produce perfect drum shells that exhibit superior tone, optimal resonance and extreme strength.
