I appreciate everyone's input trying to help, but I seem to not be asking the question right.
Regarding my EQ settings, I tend to dial them to where they feel good and leave them alone. I use several pedals as a preamp that drive my tone, but I will play with adjusting the mids again to see what happens. It is rare when I'm not right on top of my cab (literally bumping it with my back). The rare times that I do have 6-8 feet between us, the same basic situation is present - yes I can hear it better, but it is always much stronger when I'm on a wooden stage.
But the settings have been set like that for a while and were identical from Saturday to Sunday. The only difference between Saturday and Sunday was the venue; both smallish clubs, one on concrete, one on a little platform stage. While playing with them might help in general, they are not part of the issue I'm trying to solve.
I have had it set up so that one speaker is on end (on concrete) when I forgot my stand one gig. It didn't sound good.
I did note a post or two that addressed my question and it sounds like I can't get away with a small wooden platform to trick physics into thinking my cab is on a wood stage, which what I was asking, so thanks, I won't waste my time trying to play with this concept.
