I just used Recabinet..I actually didn't like it when I panned the IRs, so I kept them in the middle & left the speaker dynamics in the center, which I believe added the Recabinet speaker breakup sound so it is modded a little bit. If I had Pro Tools, I could have played around more, but I didn't get PT with this 11R so had to make the IR, then try it out.

I used Voxengo Deconvolver, imported the test tone and put the cabinets on it then exported that as a wav. After that, just open the test tone and the new wav into Deconvolver and it makes the new IR.
