Without a photo this is the best I could come up with, note the "physical port length" is at 22.5" and if you measured down the portwall to get 22.5" the port is actually longer.
This is assuming its .75" materials, a 3 common wall port, double baffled, sub up port back... again... its just a guess and doesn't account for driver displacement or bracing.
Op... do you have a photo you could post or supply more info?
