Anyone know about these, the v2's? I was poking around an noticed they had added this to all of the speakers, but couldn't find any info about it on Axiom's site. Does anyone know what differences/changes were made to require the v2 to be added? And, if I'm not mistaken, the prices went up...weren't the M22's $440/pr? They now show as $460/pr. I'm just curious what, if anything, is new and/or improved about them.
