I went a completely different direction. When the Mesa TT800 came out, along with the very compact, lightweight, and ridiculously loud Subway cabs, my search was over. I don't regret it one bit. I now have the TT amd two of the Subway 115 cabs. I'm all set.
Last week I played a small bar and took just the head as a fancy DI. This week I'm playing an outdoor party. So both cabs are coming (very large yard and part of a rivier we're trying to cover).
My rig is small, modular, loud, and sounds great. I'm all set.
