lol, yeah, epic fail by me, haha. I had two tabs open with this and I thought they were different threads, and screwed up, haha. I have modeled a BTL 15" in bassbox pro and it actually did pretty good in a small box. But it would probably need 4K in the box. Still, yeah, 15" instead of 18".
I bet I look like a real twit after failing, haha.
