bkolfo4 Posted May 28, 2012 Report Share Posted May 28, 2012 It is actually .5" off because I forgot to factor in the .5" added by the thickness of the wood where it butts up against the other piece at the 90 degree turn. The way you have it drawn with the dimensions you listed, the port is only 4.5" wide. The pieces would need to be 15"/9.5", and 21.5"/16" for a 5" wide port that is 31" long. Why are you using .5"? You do understand the port can have a lot of pressure inside it just like the box. Round ports can be thin because they self brace by design.

bassface Posted May 28, 2012 Report Share Posted May 28, 2012 Does port flex affect tuning? Quote Link to comment Share on other sites More sharing options...
