These are some marching tenors/quads/quints whatever you wanna call em. Typical for any high school marching band to have 2 of these or more. My HS drumline is at 2 tenors. They are tuned lower than a snare drum but higer than a bass drum which puts them in the tenor range of sounds. These are some of my favorite drums ever and I totally wish I had some expensive high-quiality ones lol.
