I'm a huge DC fan; I absolutely love designing for them; unique company IMO. Nobody seems to do it like like they do. They are some of my personal favorite subs, and I very seriously mean that. DC's unique suspension setup makes them absolute monsters; you can fit so many DC's and so much wattage in a small box space. That's super awesome for very loud small ported boxes with full range, pretty good sound, and it's also savage for series 6th orders. A DC sub might be the absolute best subs in series 6th orders, as far as performance to box size goes. IDK if you can beat DC in performance to box size.
