well, if you want to talk about specs- the C4 is only specified to 27hz vs. 28hz for the C2. weird eh? i would much rather have separate mid drivers of the C4, but i would be shocked if the C4 didn't have tons more bass than the C2 with the addition of 2 8" drivers.
ps. i would absolutely rather have Sophias than C2s (which are pretty much the same price point used)
