OK, we seem to have confirmed a 60Hz electrical noise. Can you hear anything in the speakers? If no, I wouldn't worry about it.

I hear hum if I put my head on rear speakers. Surround and Front speakers are fine. What's really driving me crazy is that REW is not showing the FR up to 20K. My previous laptop that I was able to do on broke and I lost everything. Bought a new one and after installing latest REW version (not Beta), when I take reading, it goes up to 14K and then drops. I know that I didn't have this issue before. I did make changes in room by taking out my previous room treatment and replaced them with 703 ownen. But I really don't think that they would cause this issue. In fact, I even have less treatment than before so for sure it shouldn't be the treatment. My speakers are capable of going up to 21K and have 106dB of sensitivity. So its not the speakers either. I think its something with the setting in REW? Any idea Jerry????

Does the upper cutoff vary between measurements? If yes then change REW > Preferences > Soundcard > Output Buffer

I don't think it has anything to do with the specific issue you are seeing, but you should always install the REW software version shown here: http://www.roomeqwizard.com/beta.html.

There is no need to be reluctant just because it says beta. The fixes and enhancements since the last "official" version are significant.

And as for the HF roll-off, I have never seen that, so have no advice for you.
