Around 10 to 12 o'clock. I'm loud..... but only on my side, near my amps.
You should look into using sound baffels in front of the speakers. I've been doing that since 1986. This allows you to turn the amp up, without blasting out the sound guy or the people in direct line of you amps. The ones I used for years were made of the drop ceiling stuff on a fold out frame all painted black. Joe Bonamasa is using plexi glass placed about 1 ft in front of the speakers. The plexi might be a little harsh, but should still do the trick. It allows you to turn up to where you can hear and feel it, but it will sound normal to everyone else.
