Hello, everyone, i just have a quick question, this is my first time building a ported box, so it may sound stupid..I drew up a pic to ask my question easier. for example, I'm required to make a 12" inch port. do i cut the piping at exactly 12" and install it (Diagram B) or do I have to factor in the thickness of the mdf which would mean I have to cut the piping at 12.75" (Diagram A)?



Thanks =)

 

Yes follow diagram B.

 

cool...thanks guys
