Anyone compared good 4" to good 5" or 6" spkrs in the front?

I played around with my equalizer and got them to sound alot better. They sound pretty much as good as they sounded in the speaker shop now, pretty good for a dinky little pair of 4"ers. I had the 6.5" infinity reference 6022i's with the exact same deck in my old car and I really miss them though, so much more low frequency but the infinity 4's do sound really good. Maybe someday I'll hack the hell out of the door panels and do a semi proper install on some 6.5's somehow.
