Guys, will RAINBOW DL-C4.2 4" (2 way comps) be any good SQ wise and also fitment wise in the E92's? I'm looking into these but haven't seen them on this forum anywhere. I understand that Rainbow 210.25 NG are fairly popular but again what is the verdict between the two variants here?
Now: E92 335D
Gone But Not Forgotten: E90 320D Alpine White
