Hi Keith - what was the setup at the venue, was it floor or hollow stage? I've noticed a big difference between 2x112s at home and on a stage...also (maybe my hearing) but competing with the other 6 in our band, I've been unhappy with the stage sound, but have been told it was loud, clear and sizzling out front. Maybe try cutting the bass and increasing high mids and treble when your at battle volume, or DIing to PA and just have high mids/highs through the PA and staying flat for your stage setup.
Cheers from another '71!
