Designed for power durability & quick decay. The Sabian AAX 18 Marching Band Cymbal features an innovative dynamic focus design which delivers total response accuracy at every volume. These innovative marching band cymbals can be playing at any volume from very low to extremely high whilst maintaining the same timbre. With a large bell these marching band cymbals help to increase the overall projection of the sound. A regular finish produces a bright sound with volumes that can be controlled easily to suit your music accordingly. These cymbals are 18 in diameter & have a quieter sound & less sustain than the 19 & 20 alternatives.
