7 cubes at least and a good amount of port or possibly aero for an ext. CabUnless you're wanting a pretty good sized enclosure it might not be $300 plus...LMAO
Just got everything up and running the other day, and I'm loving the quality of the box. Great job, and sounds SO MUCH better than my previous system which featured a pre-fab from the flea market. I don't get that muffled/muddy sound that would take away from subs like I did with the pre-fab. Also, you were great with updates on the enclosure, shipping and turnaround.
