wL<3bass Posted March 29, 2010 Report Share Posted March 29, 2010 i have a 16cubic foot box. just under that after sub displacement You have to calculate port displacement, but I would go with 16-18sqinches of port area per cubic foot.

hhowell1990 Posted March 31, 2010 Report Share Posted March 31, 2010 search for torres under the member section and download his box calc. it'll tell you what size port you need for your air space and tell you what tuning you'll have for whatever port length you have Quote Link to comment Share on other sites More sharing options...
