I guess that is the million dollar question, do I get a bigger bookshelf or go ahead and get the M80's. Would the M80's work ok so close the right wall and with the rack behind them? Assuming that the sound would be better than the Axiom 22's? Guess what it boils down to is if the M80's do sound better than the 22's in my space and I dont spend the extra money I will be kicking myself ;-).
