Sounds like Axiom is the way to go for me now. I noticed you had the EP500s. I read a review online that some folks say the EP500s synergize better with the M80's. Any insight/truth or first hand experience on this? I wonder why this would be so. I can go with the EP500s also to save some money if the sound will be close between these 2 subs. I also wanted a sub that looked like a mini fridge for a change from the boxy subs everyone's used to. Looks like a real mighty sub standing at over 3 feet tall behind the couch...bottomline, it's still the sound quality that matters to me, of course. So what do you recommend or think, EP600 or EP500? Thanks!
