Default Wide respones out of a DC lvl3 15"

What sort of box would you guys recommend? It's still more a thought than anything, but my 3 cube ported box is missing out on a lot of bandwidth.

according to torres calc and displacement of woofer and port that would be 3.26cu tuned at 33hz the psp ports are what 17in in length? 8.67sq in port area what is your sub sonic and LPF set to? should be about 60-70hz ish for the LPF.. and subsonic usally around 7hz below tuning if im correct prob about 25hz? if im wrong someone can correct me but that box should be pretty nice for that sub maybe lacking a little in port area... maybe should have done like 3 :4in aeros that would give you about 12sq in port area but need more then 17in port length which i use PVC if thats needed longer then 17 and flare yourself about 22in give you a tuning of 35hz and 3cu for your sub after displacement.

I'm going through the same thing with my box...3 cubes with a single 6" aero tuned to 33 hz like above. It gets nasty around vehicle tuning but the low end response sucks...even at tuning. I've come to the idea that I'm using that box with an 8" aero now for my SPL box and building a 4th order with 2 12's for my daily setup...

You're not alone with the loss of bandwidth OP lol
