MB 6x9 vs. JL 5x7/6x8? I don't care what anyone says about 6x9s. I bought ADS 6.5" comps (retail $299 on sale at ebay for $99 last week) on a tip from an "expert" in another forum and they're great (well-balanced, etc.) but don't fill up my car like a 6x9 and the bass doesn't compare. They sound a lot like my Polk MOMO 6.5" in the front.
And why are some of these speakers advertised as 5x7/6x8? What size are they really? They can function as one or the other?
