Mapex Quantum bass drums represent a significant advancement in the evolution of the marching drum. A lightweight contemporary tube lug ensures the best possible alignment of tension rods and keeps tuning stress off of the shell.
Quantum drums' minimal hardware-to-shell contact allows the utmost resonance. Progressive air-hole venting creates a more consistent sound and feel throughout the bass drum ensemble. Chambered aluminum bass drum hoops (precision crafted in the KHS bicycle factory) eliminate the need for Quantum bass drums to have additional rim protection, and provide superior overall strength while maintaining classic styling and sufficient tuning flexibility.
