412 CVX Posted August 6, 2012 Report Share Posted August 6, 2012 the displacement should be closer to .45 you've got to add the displacement for both subs.

AMI CUSTOMS Posted August 7, 2012 Report Share Posted August 7, 2012 Tuning is a little low, port area is low, net cubes looks good. 9 cubes net 17-18 sq inch of port per cube tune to 38 hz.

Cutdeluxes1 Posted August 7, 2012 Author Report Share Posted August 7, 2012 (edited) Forgot to check the sub up box....lol Edited August 7, 2012 by Cutdeluxes1 Quote Link to comment Share on other sites More sharing options...
AMI CUSTOMS Posted August 7, 2012 Report Share Posted August 7, 2012 I would do the port the full length of the box so you only have one port wall to do, so it would be something like 45 x 3.5 by 18 long. I did 45 width cuz I am assuming you are doing double 3/4 inch mdf all the way around making it 1.5 inch.

I did 45 width cuz I am assuming you are doing double 3/4 inch mdf all the way around making it 1.5 inch. I was planning on doing double, but couldnt get the numbers I wanted with the limits in outer dimensions. all of these scales are with .75 instead of 1.5 for wood thickness. the box will be attached to a false floor, and is also double baffled so that gives me top and bottom. then I was going to add a piece to the port face and rear, and brace from left to right.
