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
