This is a 120' x 75' space in a hangar that we are setting up for a speaking event.
We have set up for this in the past with these speakers: https://www.adorama.com/dbtarena12.html arranged around the seating area.
I'd like to think we can do better, but there is a concern with reflection off the hangar doors in the back.
I thought about stacking the speakers on either side of the stage, but I don't have a great wat to secure them, and they are a little too narrow to stack nice like DRs or Otops

Any ideas on how we could arrange things differently, or is this acceptable?

Point sources never work well in reverberant spaces as they have very little vertical pattern control. It's a tailor made application for line sources.

what about reflections from the back wall and causing feedback issues? Or are we talking about two separate issues?

Feedback only happens when the mic is close to the source. What you will get is reverberation that's why a gym sounds like a gym.
