I had been running an Orion HCCA 12D in their reccommended size 2.25 with 4X12 port for two years....the box was damaged as my leaky trunk split it open. I know this sub can sound better and I was unable to find anything searching on here....any other size box I should look into making this time. I have the specs if that helps. I am feeding it 1200 watts at 1 OHM so power isn't a problem.
Edit - I would like to get as much SQ that I can out of this sub (I know it won't be that much) and hopefully have it tuned lower than my last box at 32hz.
