I currently have been experimenting with placement with the Aeon i's and have had mixed results. In the first few days of trying different toe-in's, width distances, distance from back walls, angle adjustments through the spikes, etc, I thought at times I had the best placement for the speakers. But when I experimented some more I found new heights the Martin's were able to achieve. Here's my questions: How do I know when I have the best placement? Is there an exact formula? Are there standard ratios to use? I love the way they sound now and therefore i'm afraid to move them, but I felt this way a couple of weeks ago until I got the nerve to move them. It was then that I found an even deeper soundstage with more involving music. Maybe it's just me, but such small adjustments can make a noticeable differnce for good or bad. Any suggestions? I believe my current settings (approx) are 7' 6 wide, 35" off the back wall, a mild toe-in (who knows what that means because I don't), and my listening seat is 9'. I belive these are close measurements but not exact. Thanks, and if you need more info, or more exact measurements please let me know if this will help in your suggestions
