I have a 10w6v2.

I don't understand how they figure the Slot Length at 30". The 2 baffles forming the slot are EL = 17.25 and the unidentified one which is D (10.75) - .75 -.75 -1.25 = 8". So the baffle length is 25.25. Where does the 30"" come from???

Because if you actually lay out the box the way they describe, that 17.25" long piece ends up being 1.25" from the right side of the box, which makes the actual port length wrap around that back right corner of the box.
