Weeeelll, that would be a stretch i think. I have used it in a very small folk club that held 30 or so sit-down folks in the room and it was ok. But mainly i use for house/living room concerts, backing an acoustic guitarist/singer. For that sort of small gig it is plenty loud and definitely a "bass" sound (i play 4-string fingerstyle). If you used two of the 112MBX cabs you would have more capability for sure though i would hesitate to say even two would be adequate for a room/club with 75+ people listening/talking/dancing.
