Theatre finally built, now acoustic treatment time.

Thank You, There seems to be a dip at 65.7Hz ? Would that be room effect ? I have 2 bass traps in the corners behind the speakers. Now should I take all treatment out and re test?

Your welcome! Most likely a room mode... You can use the REW room sim to calculate where your room modes could be... Or use https://amcoustics.com/tools/amroc

You might measure your drivers at 1 meter for a baseline... Take the absorbers out and measure if you want that next baseline...
Might not see much improvement with the placement of single absorbers... And once you have corners, ceiling and walls done you will start seeing and hearing a difference...

Next steps after physical bass and wide-band absorbers would be some form of Digital Room Correction... Lot more choices there...

Ok, I will set up some baseline measurements. Then go from there.
Thank you to all that have helped me get this far.
