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 Medium Delrin Xylophone/Bell Mallets has a clear bright tone, prompting a lot of overtones and shimmer when you play. They have a medium mallet head and a lightweight core, which allows for some extra shimmer and brightness that can sit on top of an ensemble's sound.
