Re: Mics Inside Drums - Who Does It?
Using ported reso heads on toms is not efficient as any hole on a reso head should be roughly less than ten percent of the toal surface area...any more and you may as well not have a reso because it won't make a sound. since the hole would need to be big enough for your hand it would be too big a hole for anything smaller than an 18'' floor tom. so the obvious solution is to set up without reso heads (a la phil collins).
ps: for more on ports (particularly bass drum ports) google the tuning bible.
