OrionStang Posted June 7, 2010 Report Share Posted June 7, 2010 (edited) 2 6" ports at 12 inches would put you ~33.5 hz and net volume of 7.45 (Used .5 sub disp. and .5 bracing) Edited June 7, 2010 by OrionStang Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
77-AUDIO Posted June 7, 2010 Author Report Share Posted June 7, 2010 2 6" ports at 12 inches would put you ~33.5 hz and net volume of 7.45 (Used .5 sub disp. and .5 bracing) I really don't want my box at 8 cubes it was just the max I can go! I would like a net volume of 4.75. I need a depth for the box and port length. thanks D Quote PPI dbl dinDC Level 31.77cubes net tuned to 33htz.DC audio 2.0kCT Pro Audio 8" in front, 6.5 in rear Link to comment Share on other sites More sharing options...
