One of the points I was attempting to make is that the vast majority of how the horn sounds is up to you, the player. I fully accept that it is possible and even probable that resonators make a difference in your sound, but I think that that difference is not going to be consistent and that it's not going to be consistent across all makes.models/finishes of sax or which mouthpieces you use, etc.
I think you can do sonic studies of a single resonator, completely divorced from the saxophone, and say that it brightens a tone sent to it, etc. However, when you marry that resonator to a pad and put it in a sax, I think all bets are off.
Just an opinion, of course. I definitely could be wrong and I'm not an acoustician. I just don't know of any research that proves it one way or another.
