Get the most drum configuration options with the SPL Birch Competition Marching Tenor Quads. They feature 7-ply all-birch shells for a bright, highly projected sound while maintaining low-end attack, ideal for halftime shows, parades, pep bands and more. Shells include 8”, 10”, 12” and 13” sizes, and we include a sturdy and rugged carrier to effortlessly carry them all. SPL uses weld-less, triple-flange hoops and Evans System Blue Marching Tenor Series drumheads, creating the open sound and articulation necessary for today’s most discerning marching ensemble.  Since all SPL marching drums are modular, you can start out with a quad and then add an SPL 6” tenor tom to easily create a full quint or two for a sextet— the slots are already available on the included SPL carrier. Or easily downsize to a quad quickly and easily. No drilling or special tools needed. All SPL Marching Quads include a free T-style lightweight carrier. With most manufacturers, you will need to spend an additional $150 to $200 for the carrier.
