and in covid times we don't have to worry about whether the audience is loud and rowdy which in my estimation is one of the biggest reasons concert volume gets ludicrous....
the Beatles at Shea was the watershed moment from where concert Spl levels started to go up.
people en masse are both absorption and a noise source....i guess i miss being at FOH in sweaty sea of people

i wonder how valid this experiment would be with 300 drunks wandering the field between the speakers and measurement mic?

Dunno. 85dBC-slow (around 103dBC peak, when you look at the crest factor of that bit of music) is definitely a "raise your voice to talk to the person next to you" level, but if you put 3000 people on the grass and got them all to scream then it would probably make the PA look pretty quiet.
Then again, though, expecting concert SPLs (where you can feel the bass) for 3000 people with that system is a big stretch. It'd probably cope okay with lighter acoustic music.
I more show that video as a demonstration of what can be done with modern drivers and plenty of power. Big sounds out of smallish boxes.

Hey guys, thanks for all your inputs! I have decided to go all in and look at building the PM90’s. @kipman725 how do I go about getting designs on them? Also if you all have any suggestions on sub designs/suitable woofers I am open to ideas.
Cheers

Subs I would go with 6th order bandpass boxes if you have the space and can handle load in/out:
skhorn = double 21"
skram = single 21"
ckram = single 21" compact (this is more like a reflex box than a 6th order bandpass as the front cover is only giving output gain in the upper range).
