You've gotta take into account other factors such as power handling as well though e.g. can any 1x10 handle up to 600W RMS?
And sorry, I'm totally sceptical that a quality 10" cab is going to sound better than a quality 12" in handling a low B in a full band mix. If you have actually come across one in your travels that's going to out do a SC, BB2 or F112 for sound quality, rather than speculating, then I'm all ears!
