I finally got bassbox pro working, no thanks to HT audio. Just had to run a compatibility check on it. Anywho, I've been doing some modeling and experimenting and I think that when I finally move the heck out of where I am (someday) I'm going to ditch the LMS Ultras when I take everything apart to paint the cab and replace them with SI 18 inchers. Then I can buy another LMS Ultra and make my own Triax.....or maybe I should 3 more and make a pentagon.
In the meantime back to trying to find good driver for a mini-sub for computer.
