loudest small cab

Playing acoustic bass mainly for shows. Band is in orchestra pit. Would like to find small-ish bass combo amp with lots of volume...especially for acoustic bass. Currently comparing GK MB112-II (200 W) to Hartke KB12 (250W RMS). Which of these would be best...or....recommend another in this size...

I'm having a real tough time deciding what bass cab to go with and hoping you fine folks I've been reading for for years can help me out here on my first post. I'm looking for a single cab that I can comfortably (?) carry with one hand that is loud enough for a 4piece progressive metal band...
