i was looking on the cdt website and they had this about about comp speaker and tweeter setup. they said that you are supposed to have the comp woofer and tweeter next to each other and not apart. they wrote that you should have another set of tweets and put them in the middle or your front pillars. my tweets are about 10-12 inches away from the woofers. is this really bad for front stage or like cdt's opinion?
