What's out there that meets these requirements? I've got a GB Shuttle 12 that's looking for its partner - ultra loud and ultra light.
Form factor is not a concern, as long as it's lightweight.
Not too concerned about voicing given the versatility of the GB, but my wheelhouse is decidedly old school - I play a grindy overdriven Rick and make use of fuzz and wah, so if there's tweeters they need to be defeatable.
Needs to be heard over a loud drummer with no PA support.
Audiokinesis Hathor series is what I'm considering right now, but I'm a bit skittish on the price. Would love to find something under $500.
My main gigs are playing loud, heavy, scary music through an SVT into one or two 412s. This is for my backup rig, suitable for smaller mellower sidejobs I'm getting calls for, and for playing generator shows where we carry gear a half mile from the nearest road.
About the only cab that I know of that comes close to two of those would be DNA's DNS112 cab. It will handle 450-watts rms/900-watts peak, and it weighs 34-lbs., but it's not cheap. Street price is $699 to $719. Reverb had a used one on sale for $450, but used ones are few and far between.
