Good grief, this thread is like attending an astro physics class. All the aural explanations and drum placement advice as well as mounting, curvature of the bass drum and drum head type is academia gone wild. I said it previously, the sound of the drum is different from the audience perspective than the drummers. I'm inclined to suggest throwing the damn thing away and using just one tom so you can get back to playing instead of fretting over something that just doesn't respond to "remedy". Unless of course this is an exercise in thesis for some college course.
