1. ## \$2 paypal for legit answer!!

need someone to figure out port length, reward will be \$2 paypal.

PM me answers, no fucking guessing assholes

putting (2) 2" port (pvc pipe) on the bottom passenger side.

the box is 1.6^3 after displacements (other than the port obviously)

how long in inches will the pvc pipe need to be in the box?

7. ## Re: \$2 paypal for legit answer!!

Do one 5" port 19" long

8. ## Re: \$2 paypal for legit answer!!

i get 6.76 long, am i doin it wrong? 1.6 and 1.572 after port displacements

9. ## Re: \$2 paypal for legit answer!!

im slightly confused on how you got the ft^3 number. is that a 4" top and 7" bottom depth? here are my numbers based on 0.75 enclosure thickness:

gross volume: 1.114 ft^3
net volume (not including sub displacement but accounting for the port): 1.073 ft^3
port area (2" ports time 2): 6.283 in^2
port length: 11.387"

assuming that you had wwo of these enclosures with one 2" port per enclosure, then the port length would be 4.753"

so what is it?

^^^^^what he said^^^^^

Your math is off, that box is 1.114 cubes with NO displacements assuming
the measurements are correct (40x14x4-d1x7-d2)
