Quantum multi-toms feature interior plies of walnut for superior warmth that results in better projection of tone and pitch. This shell combined with the deep progressive cut produces a loud, full, and dark overall sound that doesn't get choked at high tension. The lightweight aluminum tube style lug minimizes hardware to shell contact, and creates an overall appearance that corresponds nicely to the Quantum snares and bass drums. Drums come complete with back bar. Carrier sold seperately.
