AI James Posted October 25, 2008 Report Share Posted October 25, 2008 (edited) your first post says its internal volume after all displacements. port is a displacement. id help you with port numbers if you can give an acurate box volume and measurements of port Edited October 25, 2008 by James Quote Link to comment Share on other sites More sharing options...
AI James Posted October 25, 2008 Report Share Posted October 25, 2008 also you only need 3-4 cubes net each for those subs on rms power. Quote Link to comment Share on other sites More sharing options...
