I'm building a new box for my MTX T8124A, and I think I have a good design, but I have a few questions.

First, as you can see in the pictures, my box is going to be a trapezoid-type shape. Will this screw up the port, or can I figure out tuning by doing (area) x (top lenth + bottom length)? If this works, I come up with a net volume of ~ 2.1 ft^3 for box, 27 in^2 port area, 33.5 in port lenth, with a tuning freq of ~28 Hz. Does this look right?

Second, WinISD tells me the port should be 33.5" long for a tuning freq of 27.8 Hz, BCAE tells me the port should be 26.3" long for the same tuning freq. Which one is more accurate?

Thanks, Orion

There we go, pics should be working now. Sorry about how big they are, but they are small sized files at least. Let me know if you can't tell what is what.
