i got a set of dls c6 6.5" comps for sale. comes with everything, tweeters crossovers, mids, box. tweeters and crossovers have never been used, only tested. mids have been used for about a month or so. $100 + shipping. pics will be posted soon.
as for sound, i would compare them to cdt's. i don't really have much experience with the tweets because i only used them to test, but they were soft, and like laid back, alot like my cdt tweets. the mids are tight and punchy. i'm thinking on going to some 8" mids instead of 6.5's. the only reason i got these were for the mids. i bought these brand new from an authorized dealer, about 2-3 months ago. as for you current speakers i never really listened to mb quart.
