thanks for the info KIS, so it is possible that a if all elements were kept equal except depth, that a deeper drum would be louder and more easily heard verses a shallow kick.?
All other things equal, slightly louder = yes. More easily heard = not necessarily. A deeper drum produces more overtones (both high & low). That detracts from the fundamental tone, in so much as the fundamental tone is less prominent. Part of that affect is often termed as "focus". On the flip side of the coin, those overtones give a fatter sound. Think in terms of adding a chorus effect to bass guitar. Those overtones are generally lost in an amplified band mix, but can be brought back to the fore under mic'ing. A note of caution though, close mic'ing, especially on the inside of the drum, doesn't allow those overtones to resolve with the fundamental tone to produce the full sound, thus most of the "benefits" of a deeper bass drum are often lost in PA applications. A shallower bass drum concentrates much more on the fundamental. That makes it close mic friendly in most PA applications.
Talking purely acoustic (no mic's), but in an amplified band application, all things being equal, the more shallow bass drum is likely to be more readily heard. It's tone focus occupies less frequency range, therefore it stands a better chance of finding it's own "space" in the frequency range produced by lower instruments (usually bass guitar & keys).
Of course, the previous caveats apply. Shell construction makes a big difference, both in terms of fundamental/overtone production, but also in terms of volume & projection. If near field satisfying tones are your thing, & you have the mic'ing facilities to exploit them, then a thin shell will get you there. If you're especially lucky, then a thin solid shell will get you there on steroids
If your thing is volume & projection, then a thick shell is the way to go. Additionally, head selection & tuning then take over to fine tune the response. I aways suggest that heads & tuning should be dictated by the drum construction, & the drum construction chosen to give you the foundations to build from.
Depending on the drums design, & especially the bearing head choice, you should find the more shallow drum is much easier to dial in.
I hope that helps.
