By the way...the room sounds better than any room I've been in for the purposes I intend to use it for!
It just feels perfectly neutral with a natural ambiance that is still bright but not overly reverberant. It's not dead in a way that's it's uncomfortable to the ears to be in there, there is no one end of the frequency spectrum that is overbearing or attenuated compared to the others (ie too boomy, too echoey in the highs, too dead in the highs, too boxy, etc). Everything sounds neutral but still has a lively enough "room" sound to it. Like a good early reflection vibe without the nasty "early reflection" artifacts if that makes any sense. No (audible) ringing at any frequencies, no slap or flutter echoes, bass is even ALL AROUND the room no matter where you stand, sit, lay (give or take a few dB here and there in places further away from mix position), drum area is a little livelier than the middle area and control area (my intention).
Already tracked 4 separate vocal sessions in here with 4 different people (male and female all different ages and styles and different mics). With the mic placed a little off center of the room and under a ceiling cloud (and making sure to place it in line with a wall panel for the wall it was closer to), there was no need for my home-made "vox guard" aka "Mic Reflection Filter", no need for blankets or free standing gobos infront/behind/around the singers, etc. Just the mic in the room (with a pop filter of course). And it sounded perfect imo. Not overly dead but no audible sustain from the room captured even from condenser mics. I will ask the guy who is mixing it how it turned out but the tracks sounded great that day upon playback, both in headphones and the monitors.
