The New Armory Series replaces the old Meridian Maple. It features the amazing Maple Birch Hybrid Shell that was so popular on the Raven kits and features new Soniclear Bearing Edge, which is standard on all Armory shells and allows the drumhead to sit flatter and make better contact with the shell. The result is a stronger and deeper fundamental pitch, effortless and consistent tuning, and a significantly expanded tuning range. For the serious player, the increased head to edge contact increases shell vibration, allowing the sonic nuances of the Hybrid shell to stand out.
