I hold JimmyM completely responsible for Ampegs selling of mixed cabinets. You should be ashamed of yourself Jimmy.
Also, since I thought that I had read in the Mesa Boogie Subway thread that the new MB cabinets were designed to perform well when mixed, I asked a thinly veiled question, (well actually, I mentioned this thread) there about the subject, and Andy came through, (as expected) with a good response, (And Mr Al Kraft also provided a good description of the issues involved too).
I guess I can understand that nobody from Loud wants to get involved here, but I do think it would be wise for them to engage their (loyal current) and potential future customer base here the way other companies have.
