Message	resonators or did you just wing it? I've watched some videos on youtube about helmholtz resonators and they make it seem overly technical where you need to listen for the drone at a certain RPM and then do a crazy calculation to figure out the volume of the resonator necessary to eliminate the drone or something like that.
