I haven't done it the way you suggested. I take you at your word because you obviously know what you're doing. I don't really get why raising the target level is better when REW is calibrated to pink noise at 75 dB. I would have thought it was best to set the target level to 75Hz since that would aim to make the full spectrum response flat, and from there, raise the low end with a house curve if desired. I don't understand how raising the target level changes the response within the room. Oh, and I have not allowed REW to set the curves. I'll try your suggestions and see what happens... I just don't understand why it is better.
