Promark's SPYR Series is designed to be a single line of mallets that covers the needs of an entire ensemble, especially indoor and outdoor marching ensembles.
Promark's SPYR Series Large Delrin Xylophone/Bell Mallets has a strong, bright tone, prompting a lot of overtones and shimmer when you play. They have a large mallet head but a lightweight core, which allows for the brightness without getting harsh.
