Cutdeluxes1 Posted August 6, 2012 Author Report Share Posted August 6, 2012 Max dimensions are 21X48X21 in a tahoe, sub up, port back. if anybody wants to design one. Plan on starting the build as soon as possible. Quote Link to comment Share on other sites More sharing options...
412 CVX Posted August 6, 2012 Report Share Posted August 6, 2012 Design it yourself, you were close the first time. Just shrink the port area, make the port shorter, and shrink the width or depth till you get the right volume. post your results up here and we'll figure it out from there.

Cutdeluxes1 Posted August 6, 2012 Author Report Share Posted August 6, 2012 Well from the website, the box should gross 9.00ft3, with 144ft3 of port area at 18 inches long. The FS for them is 38 hz. Ive taking everything into consideration except woofer displacement. Cant find what it would be for 2 15's. since it will change the tuning and port area, should I aim for prime specs, are tune low and let the displacement put me in the ideal tuning? So far I came up with this: HxWxD 21x48x21 Port:6x18x18 which puts me at GV of 10.23ft3, PA per foot-17.03in2, tuned to 39.38HZ, but only 108in2 of port area. suggestions?

SnowDrifter Posted August 6, 2012 Report Share Posted August 6, 2012 I'm on mobile, so I can't be much help. But I will say this: you want net volume, not gross volume.

412 CVX Posted August 6, 2012 Report Share Posted August 6, 2012 okay this is the jist of how the tuning and volume of boxes mix together: 1. larger volume (no change to port) tuning is lowered. 2. smaller volume (no change to port) tuning is raised. 3. More port area (no change to volume or port length) tuning is raised 4. Less port area (no change to volume or port length) tuning is lowered. 5. longer port length (no change to volume or port area) tuning is lowered 6. shorter port length (no change to volume or port area) tuning is raised now of course, logically, when you change one thing the other things change as well. So with this knowledge, you know what to compensate for in order to get the right numbers Quote Just say no to Ground Pounder Customs.

Hunters21w Posted August 6, 2012 Report Share Posted August 6, 2012 I'd imagine the AQ's would be between .2-.25 of disp per sub if you haven't figured it out yet.

Cutdeluxes1 Posted August 6, 2012 Author Report Share Posted August 6, 2012 I think I got it. with .25 displacement and some port changes I have ideal numbers except for port area (which is 152in2). net is at 8.81, 17.25 cubes per foot, tuned at 38. Dimensions are 21x48x28, port is 8x19x18. Quote Link to comment Share on other sites More sharing options...
412 CVX Posted August 6, 2012 Report Share Posted August 6, 2012 (edited) press printscreen on your computer of torres, copy that to powerpoint, save it as a .jpg or .png, make a private album on facebook, upload it there, copy the image url and paste it here it might be a tad large for how much power you're giving it.
