Hi 1ST Post.have had m60's&vp150 cntr for about 1 mos now switched frm Polk rt800&cs400cntr.When first hooked up axioms was a little concened about cntr.sound Found had to raise db level on cntr about 5 dbs higher than mains.after doing this speaker sounds much better,the soundfield&detail coupled with the m60s in the front is just amazing Polks never sounded this good.FYI hooked up to denon avr 4800.hope this helps.
