What type of music, and will the smaller cab be just handling stage volume or having to cover the whole venue? That said, I think a Barefaced 2x12 cab would be a great solution, plenty of power handling, not too low down so only your ankles hear it, great dispersion and lightweight/portable. I’d go for one of their 2x12 cabs rather than 1x12 purely as imo it can do so much more, tho many gigging a single Barefaced 1x12 cab seem plenty happy enough.
