TeejayBee Posted August 2, 2011 Author Report Share Posted August 2, 2011 sorry 15" imo im thinking sub up port up will be best, only for the fact that if i do the sub back it will hit the hatch on flex and idk port just seems to be able to fit better up , Quote Link to comment Share on other sites More sharing options...

RAM_Designs Posted August 2, 2011 Report Share Posted August 2, 2011 (edited) Okay olds boomer got a some dimensions for me, Box idea one Height Width Depth 17.25 37.5 16.5 Port Height 15" Width 3.75 Length 22" tuned to 32hz 37.5" x 17.25" x 16.5" = 4.92ft^3 before sub and port displacement 15"x4.5"x22" = .86ft^3 for port displacement Left's say .15ft^3 for sub displacement So without any bracing you're looking at 3.9ft^3 after displacements. A 3.9ft^3 box with a 15"x3.75" port that's 22" long gives you a 37hz tuning. A 32hz tuning using the same net volume would require 31.75" of port length. It looks like he was finding the port length based on the gross volume of 4.92ft^3, which is not the right way to do it.
