With just that stuff at the early reflections, there is still a ton of reverb in the room behind mix position, just did the clap and snap test, no music yet. There are a bunch of flutters between the bare floor and bare ceiling, hence whey i am hanging 8 ceiling clouds around the room and will have a thin area rug in the center. There is some modal ringing on a specific note or two when i go through a lower vocal scale when i am standing closer to the center of the room (untreated). So I am hoping by adding all the wall panels, more wall/ceiling bass trapping, some diffusion and ceiling clouds, area rug, and other stuff that break sound up (mic stands on walls, cables on walls, guitar amps, keyboards, spare percussion on stands) will remedy all of that. If there are still issues when i am done putting up all the planned treatment, I will attack that then.
Edit:
But the bare room compared to now is already like night and day. Just adding the superchunks in 4 vertical corners cut down a lot of boominess as well as reverb immensely. Reverb time before was like 1.5 seconds and with just superchunks it was down to about .5 sec.
