got the box built, but we are going to have to add more braces inside the port to keep the back of the box from flexing, my question is will this lower the tuning or raise the tuning by adding some braces in the port

ne one i was just wondering what the bracing is goin to do to the tuning, raise or lower it. thnks

i believe the tuning goes higher the more airspace you take up and port size doesn't change.
