Loud crowd - not too many rowdies at chamber music, so I'm guessing it's pretty loud show.
Balcony - sounds like a pretty small venue.
If that's all I knew about a room I'd never taped, I would probably go with the Hypers in a DINa config. May not be the "best", but it's a good place to start. If the acoustics are good, run cards the next time out. If you are not familiar with how much boom you might encounter, the hypers may be a better choice for a first run.
