The high-end drumhead, made by REMO USA! Dunnett R Class Res-O-Tone, Res-O-Two, and Felt Tone drum heads represent a subtle but completely new approach to the traditional drum head. While working with Remo to develop the new Felt Tone bass drum heads, Ronn Dunnett devised a simple, unique and original head design using Remo films. The Res-O-Tone and Res-O-Two drum heads are based on the Remo Ambassador and Emperor models blended with Dunnett's proprietary film combination (patent pending). The resulting heads produce unmatched resonance, have a broader tensioning latitude, and have fresh sonic and kinetic characteristics. These heads also have an uncoated Timpani film and a unique semi-transparent finish; Tympanica is how Ronn Dunnett describes them. - Exclusively made for Dunnett by Remo USA - Uncoated tympani film - Expanded tension latitude - Unique semi-transparent finish
