Evans Reso 7 Resonant Coated Drum Heads are designed for drummers who desire a good amount of articulation from their toms, but want to cut down on excess ringing. Reso 7 heads are constructed from a single ply of coated 7-mil film. This coating and thickness gives you a warm initial response and a very short decay without the need for any external dampening equipment. The Evans Reso 7 heads deliver a bright focused punch that will sound great on stage or in the studio.
