Guest Posted May 15, 2012 Report Share Posted May 15, 2012 how is the port taller than the box? Quote Link to comment Share on other sites More sharing options...
jeffrm Posted May 15, 2012 Author Report Share Posted May 15, 2012 port is on top with subs the pic is from the top. so 20in deep minus 1.5 for wood is 18.5 Quote 03 tahoe z71 4 death penalty 18s 2 ampere audio 3800s @ .5 each 18v 156.7 @ 35hz 158.5 @ 50hz Link to comment Share on other sites More sharing options...

LZTYBRN Posted May 15, 2012 Report Share Posted May 15, 2012 That's a helluva lot of displacement for only 2 woofers. SMD 18 is only .26 cuft. Quote Link to comment Share on other sites More sharing options...
jeffrm Posted May 15, 2012 Author Report Share Posted May 15, 2012 yeah i cant find the displacement for my atomics so i found the equivilent from rd and theres say .31 per sub Quote 03 tahoe z71 4 death penalty 18s 2 ampere audio 3800s @ .5 each 18v 156.7 @ 35hz 158.5 @ 50hz Link to comment Share on other sites More sharing options...
jeffrm Posted May 15, 2012 Author Report Share Posted May 15, 2012 so other than the displacement being off some does it look good? Quote 03 tahoe z71 4 death penalty 18s 2 ampere audio 3800s @ .5 each 18v 156.7 @ 35hz 158.5 @ 50hz Link to comment Share on other sites More sharing options...
Joe X Posted May 15, 2012 Report Share Posted May 15, 2012 Well you should probably seek larger port area, and at least check for manufacturer recommendations on net volume, many 15s work well above 3 cubes. Quote Link to comment Share on other sites More sharing options...
jeffrm Posted May 15, 2012 Author Report Share Posted May 15, 2012 So what I need to do is make the box bigger and adjust the port accordingly. I wanna do a interchangable port for daily and spl. How can I do this? Quote 03 tahoe z71 4 death penalty 18s 2 ampere audio 3800s @ .5 each 18v 156.7 @ 35hz 158.5 @ 50hz Link to comment Share on other sites More sharing options...
