@fast A couple of recommendations... 1st, put a rug or 2 on the floor in front of and in between you and the speakers. Next, I strongly recommend the triangular type set up... Meaning your distance between the center of your speakers is the same as the distance from your speakers to your ears. In this case, you can normally get that full width distance before your soundstage will collapse, this gives you a large spacious stage. Next, What you stated for tow in is reverse.... a full tow in (pointed at your ears) will give you the fullest most detailed presentation, but can show peaks in the room or any abnormalities... So, start with a full tow, then turn the tow outward a few degrees at a time, until you have tamed your response or in this case the harshness or screeching sound. I use a cheap laser pointer along the side of my speakers to get alignment correct between left and right channels....
This should help, Good Luck, Tim
