I will model it up today, but in my experience it should work
out slightly smaller net and tuned slightly higher once all
displacements are accounted for. But it will still be a great box.

Total volume gross : 5.783
Port volume: 2356.59 / 1728 = 1.36
Port wood volume: 27.25 x 13.5 x .75 = 275.9 - 275.9/1728 = .16
Speaker displacement : .15 + .15 = .30

Total displacements = 1.82

Net volume = 5.783 - 1.82 = 3.96 cubic feet

Port length: 33.25
Port area: 5.25 x 13.5 = 70.875

Approximately 4 cubic feet at 34.3hz

Just to close the loop, in pm's I told Bushk311 to
modify the re calc to have 34.5" width and 14"
p2 to make it closer to 4@32hz.
