Do Deeper Bass Drums Really Produce A More Powerful Tone? Let's Do An Experiment And See...

Before 1980 most every drum set bass drum was 14" deep. Nowadays an 18" depth is pretty standard. What's the difference sonically? For a couple of decades now I have been noticing a trend in performance between shallow and deeper bass drums when miked, and I have finally decided to put my observations to a test. Join me and let's have some fun!!
It's the most fun you'll have all week! ;)
