412 CVX Posted November 2, 2011 Report Share Posted November 2, 2011 unless you're doing a 15" W7 which i don't think exists, 3 cubes seems like a little much. also if you moved the vertical dowel over a couple inches, it might be more effective. Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

soundcheck11 Posted November 2, 2011 Report Share Posted November 2, 2011 1.7 ported is roughly what you need for 12-13.5" w7 Quote Link to comment Share on other sites More sharing options...
soundcheck11 Posted November 2, 2011 Report Share Posted November 2, 2011 13w7 is 2.375cuft ported for 30hz 12w7 is 1.75cuft ported for 32hz 10w7 is 1.5cuft ported for 32hz 8w7 is 1.0cuft ported for 32hz i have 4 12w7's they play good in an 8cuft box tuned to around 30hz. I had 2 before that and it sounded amazing in just under a 4cuft sealed box. So, id suggest getting your box very close to these specs and it will sound pretty damn good. Good luck Quote Link to comment Share on other sites More sharing options...
RAM_Designs Posted November 2, 2011 Report Share Posted November 2, 2011 If you're running limited power to a 13W7, that box will work just fine. Don't expect to be able to put a whole lot of power to it though.
