OK, all this talk about slanted cabs having "less volume" than straight cabs and straight cabs having "less standing waves" is all way ridiculous to me. Sorry to sound confrontational but if you're going to claim such things please back this up. For one I can't imagine how a slanted cab would mystically have less volume over a straight cab wired the same way with the same speakers. Please explain how this would be and please don't come up with, "Technically 1db is lost in....". Secondly, for the other poster, please explain how four speakers all straight would have less standing waves against a flat back than 2 flat and two angled up.
And after all this anyway... can you guys honestly say this makes any difference whatsoever to a mic in front of *one* of the speakers for a recording? Come on now
