andym85 Posted January 26, 2008 Report Share Posted January 26, 2008 im not sure...is it an "L" shaped port? if i use my calculator then.... the wood for the length of L1 is 18.5" (L1 however is 20.5") the wood for the length of L2 is 3" (however L2 is 5.75") total port length is 29" (20.5+5.75+2+.75=29) this is due to end correction (half the ports width...so 2" plus the thickness of the front baffle...which is .75") thats about 9.83cubes at 32hz im not sure if that makes any sense withouth a picture, but i could draw it up for you if you would like i likes me some audio stuff...

Decaf Posted January 26, 2008 Report Share Posted January 26, 2008 ahhhhhh, well ur port is 4in wide right? then the actual port length is 2 inches longer than the port, then a 90degree angle, then another 2 inches plus the end correction which accounts for i think 6 inches, myabe a bit more 19.25 + 6.75 = 26in Link to comment Share on other sites More sharing options...
thegr8cody Posted January 26, 2008 Author Report Share Posted January 26, 2008 so do i add 2 inches for end correction?or is it already in there i think i know what your talking about but does that mean i make the port 26" or it'll already be 26" long making it 19.25" 1998 gmc sierra h/u:eclipse cd3200 sub:dd9518g d1.5 amp:jl e300/4 sub amp:dd m2a front stage:id ctx65cs dc power 270 alt lots of kicker 1/0 Link to comment Share on other sites More sharing options...
Decaf Posted January 26, 2008 Report Share Posted January 26, 2008 it will be tuned to the length of 26 if you make it 19.25 length port 4 inch wide Link to comment Share on other sites More sharing options...
