I just saw this..... [URL]http://www.AudioAsylum.com/forums/MUG/messages/57129.html[/URL] And had to try it on my Aerius i's I used some folded hand towels to fit the "shelf" behind the electrostatic panel. Well seems to be something in the placement of sound absorbtive materials here.... I'm going to experiment with different materials so expect an update in the near future. So come on all you Martin Logan fans get your towels out.
