I'm using an lb30 and (walbassist's old) lb212. Sounds lush, but the 2*12 is still pretty heavy - although the Ashdown website quotes something silly like 14kg, the cab weighs significantly more. This one is closer to 23. BUT there were only something like 20 of these made so they're, for all intents and purposes, prototypes and the quoted 14kg was probably calculated rather than measured. And it's still lighter than the vs212. Just thought that might be useful.
Tried the lb30 with several cabs, including my tech soundsystems 4*12 and an aggie 1*12, and it always sounded good.
