Generally speaking I think most people will like a much hotter low end response, probably at least 10db hot and sometimes more. I'm not referring to a house curve for your bass response, but rather more of a whole house curve.
We generally speak of house curves for our bass response only around here... gently rising 8-10db from 80-100hz to 30-40hz and leveling off on down to 20hz and below. Even if we were to keep that area flat, I would believe a hotter overall bass response would be better.
Wayne wrote a pretty good article on all this
here.
I can't say everyone would necessarily like it this way, but it seems to be more popular and natural for most people.
