I'm debating on going with coaxial 6.5 or just throwing my sound qubed 6.5 pros in the rear and calling it a day. I have the JBL MS-8, originally I skipped the rear but I have read that the MS-8 can make good use of rear speakers so I was thinking of trying it out. So the question is will the sound qubed 6.5's I have do a good enough job or should I get a coaxial set in the $150-200 price range. I have a 6 channel amp so the rear speakers will be powered.
