MapexQuantum Mark II Drums on Demand Series Blue Ripple Bass Drum 20 in.
Independent shopping perspective
The Korena take
For a 20-inch marching bass position, the Quantum Mark II Drums on Demand in Blue Ripple brings a durable premium-wrapped finish intended for school color combinations and marching uniforms. Its six-ply maple shell holds a consistent 14-inch depth, reinforced at the edges with 2.4 mm birch rings. The SONIClear edge seats the head flatter against the shell for warm, rich resonance. Air vents matched to the drum size keep the voice focused and reduce sustain; external eyebolts permit head-on height adjustment.
Strong match
Who this is for
- Marching groups selecting a 20-inch bass drum in a school-oriented Blue Ripple finish.
- Uniform-coordinated marching setups using either traditional or contemporary uniform styles.
- Player swaps during rehearsal that call for accessible height adjustment.
