I think the take-away quote from this article -- and one that applies equally to speakers -- is this:

"If no one can tell the difference, what's the point?"

You all know the thread I'm talking about... I like the way Axiom slowly iterates their speakers toward that unreachable goal of perfection. With data and testing. Sure, they could add more bracing, but does it make an audible (positive) difference? They could also make their crossovers prettier to look at and/or use more expensive components, but would that make an audible (positive) difference?
