I'm really looking for someone with experience, but I need something for the rear and I can't decide between running two CDT M6+ 6.5" mid-bass or a single 8" subwoofer like an ID8. I'm not worried about being loud, I want something that's accurate...clean, through a wide range. Up front, I want to run CDT 2-way compenentsl: M6(not the M6+, which is a little different) and ES-01 tweeters with their Upstage system. The MD6+ get down to about 10hz btw. Which would be a better combination with those components?
