Martin Logan's Speakers Placement??

The Aerius speakers are a pain to place. Even moving them a half inch can change the soundstage/sound. I agree that in general, 3-4 feet from walls is a good start. These speakers also have a narrow sweet-spot. It is important to keep the listening position constant during set-up. It's a lot of work, but you'll know when you get it right: the speakers will sound great! Good luck!!!

Thanks folks on all your suggestions...and you're right, the mid-range, sound stage, vocals details, and airiness produced by ML are amazing.

Btw, my wife's plants (~6' tall) are behind (in between) my ML. Think I should move her plants?

I believe 4 to 5 feet from the back wall is best and around 7 feet apart. Mild toe-in - shine a flash-light on them from your listening position and the reflection should be about a quarter to a third of the way across the panel.
