I just grabbed a steal on a brand new pair of Mirage Omni 60's ($80 shipped from Tweeters). Now I need two stands for them. I plan to use them as front mains and there will be two Mirage Omni Micros as rear surrounds. How should I position the Omni 60's in relation to the surrounds? Can they be right in front (duh) of the rear surrounds? (The center channel is on top of the TV and the Hsu subwoofer off to the side.) Should the stands be higher or lower than the rear surround stands - or the same height? I am looking at Omni Mount stands on eBay but there are different kinds and heights and I want to get it right. Thanks!
