How high are you needing these mids to play? The Anarchy can play up to 2.5k easily, and has a ton of useable throw. I'm not sure how high the DD's can play but they have great midbass as well...anything at partsexpress is not going to compete with these two drivers in terms of sheer midbass capabilities.Been looking at parts express drivers also. Just haven't heard any in person.
its been a while but I think it was 2.5 cu ft...i originally buit iy for 3 DD 8's....then changed my mind...so i'm thinking 2.25 plus port...its slot ported on the sidewhat was the specs on that dd box? I have been kicking the idea around to use 4 or 6 6.5 subs. Either the tang bands or the dd's. I just like the shock factor when people figure out you dont have a 12 in your hatch.
