Autruche Posted November 28, 2010 Report Share Posted November 28, 2010 Damn, that's a big box for just 2 xl 15s. Shoot for 6.5-7.5 cubes after displacements, 7 cubes should be good. Looking at like 120 square inches of port, should be golden. As far as tuning, if you're unsure between 33Hz and 35Hz tuning, just tune to 34Hz. It'll still get down, but sound great, musically.

fritosaregood Posted November 28, 2010 Report Share Posted November 28, 2010 Honestly you will probably never notice a difference... this^^^ and if your worried about your box playing well below tuning, your port area will play a bigger factor to play well below tuning should it be bigger or smaller port area? sorry to thread jack Smaller Quote seller feedback: http://www.stevemeadedesigns.com/board/ind...showtopic=61719 http://www.stevemeadedesigns.com/board/ind...showtopic=68281 build log: http://www.stevemeadedesigns.com/board/index.php?showtopic=44800 Gf's build: http://www.stevemeadedesigns.com/board/topic/54346-kickergirls-camaro-new-box-pg-5/#entry753970 Link to comment Share on other sites More sharing options...
nosho47 Posted November 28, 2010 Author Report Share Posted November 28, 2010 I tweaked on it a little more and i got port area per foot: 15.10 net volume: 7.53 cu.ft tuning frequency: 34.95hz Quote Link to comment Share on other sites More sharing options...
-Hobby- Posted November 28, 2010 Report Share Posted November 28, 2010 I would try and keep it around 7 cubes net or a little smaller and use 35 - 36 hz tuning. 15 sq in of port per net cube should be fine. Quote Link to comment Share on other sites More sharing options...

nosho47 Posted November 28, 2010 Author Report Share Posted November 28, 2010 what about this one at 7.53 cu. ft @ 34.95hz Quote Link to comment Share on other sites More sharing options...
hdorre Posted November 28, 2010 Report Share Posted November 28, 2010 I think you'll be surprised if you build your box to 8 cubes... Unless you've done it, dont be talking smack about it... I've had 1 and 2 15's, and used several different sized boxes, and on a single 15 I had 5.5 cube, and it was great, on 1 and 2K... OP, you'll be fine at 8 cubes... What subs were you using? And you do realize the the OP is using 2 Sundown 3ks on 2 XLs, right? I'm guessing he will strap the amps at 2 ohms.
