dwright27 Posted March 9, 2009 Report Share Posted March 9, 2009 in my "box/wall" the 2x4's will drop my volume, and if i keep my tuning the same without accounting for the volume the 2x4's bring it down then my tuning SHOULD drop as well if i dont change my port length correct?? stuck on this before i cut my port to length. 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.

Pioneer~Saturn Posted March 9, 2009 Report Share Posted March 9, 2009 If youre saying that if you dont account for the 2x4's, the tuning will go down...thats wrong, the tuning will go up due to the decrease in airspace Team Tupperware <First dual-alternator 'real' Saturn (pre-2002) on the planet>(3) 15" Fi SP4's fed by (2) M3a's strapped @ .66712.75 cubes net @ 25Hz with 200 sq inches of port area (lowz...?)Stock alt position (custom bracket) 225 amp Mechman Roof = steel and fiberglass (u mad?)(2) XS Power D3100's, (2) rhino batts, No battery upfront (for now, smh)4 power+ 4 ground runs of 1/0-gauge to rear"If its been done before...you're doing it wrong" : ) "stfu about scores and float $hit..."

bobonit Posted March 9, 2009 Report Share Posted March 9, 2009 To keep the same tuning, you will have to lengthen your port to compensate, which will also reduce your volume even more. 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...
Decaf Posted March 9, 2009 Report Share Posted March 9, 2009 this is why allthread is really nice, its very small and very strong 2x4s are huge and strong albeit, but take up alot more volume so i stick with 1 1/4" oak dowel rods, a nice compromise Link to comment Share on other sites More sharing options...

I just have to add them up to determine my final displacement, then I'll tune the ports last. 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...

Kurt dropped the 2x4s in and it dropped to around a 28 hz tune. 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.
