throttle98 Posted September 4, 2013 Author Report Share Posted September 4, 2013 Any able to please just punch those numbers in a calculator. I think the port would be 31" long and 4" wide. The face is 1.5 thick and the other walls are 3/4 mdf. Looking at my space im hoping I may be able to squeeze 4 12's in there. We'll see. Link to comment Share on other sites More sharing options...
Joe X Posted September 4, 2013 Report Share Posted September 4, 2013 Ok so I calculated your box specs: The "extension" part is 15" long according to your measurements, each sub is 0.19 cubic feet displacement so the spec of the box is: Net volume: 2.73 cubic feet. Tuning frequency: 33.5Hz. Port area: 50 square inches. Link to comment Share on other sites More sharing options...
Dan2427 Posted September 4, 2013 Report Share Posted September 4, 2013 So your port area is a little high and IMO box is a little small. Thanks joe x. I'd PM Cody on here or Jeff and ask them what they'd recommend for a box. I've never played with the XL myself heard a couple that sounded really good.. There screen names here are corona_jeff and CJ18 I believe. Tell them your box specs and they will know what you should be doing wrong/right. 2003 GMC Yukon Denali Alpine CDA 117 Redoing Mids/Highs 4 Runs of 1/0 Knukonceptz 2+, 2- 4 Deka 9A31's in back (Stock underhood) 250 amp Alt.

throttle98 Posted September 4, 2013 Author Report Share Posted September 4, 2013 Thanks a lot joe x, that explains a lot. Its supposed to have 1.5 cuboc feet each. Sp the box is small amd tuned higher than I thought. Ive been talking to ram designs aboit doing a clamshell of I can get it to fit and fire it into the cabin.

WillPwn4Food Posted September 4, 2013 Report Share Posted September 4, 2013 Won't the 12s seal off if you build an enclosure that's about 14h and 35w? I was just a couple inches too high when I had my 2 15" n2's back there....

Joe X Posted September 4, 2013 Report Share Posted September 4, 2013 If you can reverse mount the subs your spec would be 3.1 cubes @ 31.4Hz, at least would tell you if the spec you aimed for would have paid off. Link to comment Share on other sites More sharing options...
