my current rig includes a 4x10 over a 1x15 and when I turn up to a volume that seems reasonable, my guitarist complains that he can't hear himself, even though I can hear him fine from where I stand, on the opposite side of the drums in our practice space (which is a ****** basement with bare concrete walls). So I was wondering if the acoustics were more affected by the wider array of soundwaves coming from the bottom cab which could be reverberating off the wall behind him and making it louder on

I'd be willing to bet dimes to dollars said guitar'd player has his amp on the floor and it's not tilted back. The midrange and high frequencies from a guitar amp (and those components of a bass amp's signal too) travel in a very narrow arc. Close to his amp he can't hear them as they pass by him south of his border; further away, where that arc shaped cone of sound is wider, you can. He, and you, have no trouble hearing you because your top cab is high enough. The 15 doesn't enter the equation at all except for serving as a stand for your 4x10.
