The Powermax Ultra White Crimplock Bass drumhead from Remo provides marching band performers with a responsive, stable head with loads of focused attack and great tone. The Powermax is constructed with a 1-ply, 10-mil ultra white film and internal inlay ring. A free-floating muffling ring with a Bottom White Dot enhances attack and optimizes tone control. And the high-tension Crimplock hoop provides a wider tuning range and increased stability — features that any marching performer will love. Sweetwater marching bass drummers continue to be big fans of Remo drumheads due to their excellent quality and stellar tone.
