Crandis16 Posted June 23, 2012 Report Share Posted June 23, 2012 I have also heard that port on the side is louder than in the middle if you're going for SPL, but I have no science or experience to back this up. I have a couple friends who have been in the bass game much longer than me and I usually consult them for any questions. pics would be nice Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...
CJ18 Posted June 23, 2012 Report Share Posted June 23, 2012 Stick with the middle port. You could run into loading issues with the sub closest to the port if you co that route. Quote Link to comment Share on other sites More sharing options...
jmorlan Posted June 24, 2012 Author Report Share Posted June 24, 2012 are we out of ideas? would like to choose between firing back, port in middle, or firing up, port along bottom. would like to try to construct tomorrow since i have access to a table saw. I know this is kind of beating a dead horse, with just about everyone having diff opinions. not trying to compete, just in a DD, want it to hit lows, but still sound good.

just1moreamp Posted June 24, 2012 Report Share Posted June 24, 2012 In suv subs up port back. if 24' is to deep then do 18'tall 50'wide 22''deep. Quote Link to comment Share on other sites More sharing options...
jmorlan Posted June 24, 2012 Author Report Share Posted June 24, 2012 (edited) did that design you gave me, have a port down the bottom, and the middle? also, that double walled design. no go. EDIT: would it be better to port along bottom facing of box, or down the center? Edited June 24, 2012 by jmorlan Quote Link to comment Share on other sites More sharing options...
just1moreamp Posted June 24, 2012 Report Share Posted June 24, 2012 box would be 18'tall 50'wide 20'deep port at the bottom. 2''tall 48.5'wide 24'deep. Quote Link to comment Share on other sites More sharing options...
jmorlan Posted June 24, 2012 Author Report Share Posted June 24, 2012 I think im gonna give that one a shot. whats the tuning on it? and NET cubes? throw me a cut sheet too. please. lol and or pic design like you did with the last one. i have it down, i know this shit isnt rocket science, but its been a while haha Quote Link to comment Share on other sites More sharing options...
Joe X Posted June 24, 2012 Report Share Posted June 24, 2012 The suggestion above is 5.67 cubes @ 37Hz and has a design fault in the port, the port cross sectional area ratio should be kept at or below 9:1. Net volume is rather short, 6 cubes net at least would be better and will be needing crossbracing. Quote Link to comment Share on other sites More sharing options...
