Good point Jim. I'm hearing from a few shops that players are not getting the full sound from "short stack" toms they hoped for. I mean 10 and 12" specifically. Floor toms are not an issue due to the size, but those smaller toms seem to like a little extra depth. I re visited my old 10x9 and 12x10 and I really paid attention to my tuning and the resonance I wanted to hear..And there it was!!..I just have to get over the fact they are "power" toms and not "standard"...why?, because I'm stuck in the past and evidentally, a snob!Eye Ball
Well, at risk of sounding like a snob myself, I have found most "dead" drums are due to shot heads tuned poorly much more so than because of additional depth to the shell. Deeper tons are not louder- their resonant durface area is the same. The longer air column causes them to react slower (to me anyway) and I certainly don't need to be slowed dos beyond my lack of technique!
I do think that some drums (regardless of depth) have a sweet spot where they are most resonant and really sing. This is where they will be loudest.
So, a poorly tuned deep Tom will not be as loud or resonant as a well tuned standard Tom.
Any depth will do the job but why lug around extra weight? If you need more volume increase diameter, not depth.
Ask Joe Morello what he thinks of "deep" bass drums...
