Hey folks after months of hardwork my HT is done and looks great. I dove into REW and checking the quality of sound, and notice that my highs (10k and above) actually tick back up a bit, nothing crazy but would love to hear if anyone has any thoughts. My room is 13 by 19.....treatments are OC703/705 mix of diffusion and absorption. I have 2 18 UM in the front powered by a NX6000. I have a 7.4 set up with HTM12s, and Volts powered by a Denon 6500. I ran audysses and have a flat setting. Would love to hear some feedback
