Placement of Martin Logan s

My CLS's are 5.5' from the front wall and 5' from the side walls. Panels are 8.5' apart (center to center) with slight toe in (no more than 2 to 2.5"). They actually worked -- well focused sound stage/center image -- farther apart, but I've added SW800 sub towers and had to move the panels a bit closer together. Listening position ranges from 9 to 11 feet, depending on material and mood. I have a fairly large, asymetrical room so reflections are not a major issue. I suspect they are with your speakers and room (based on the position/dimensions you stated).

Notwithstanding the fact that the Aerius is smaller, I think your speakers need more air, if this is feasible in your room. Best of luck.

I have a pair of Quest Z's. Once you think you have the placement dialed in there is another thing you can do if your preamp or integrated amp has a phase switch. If you can change the phase sit in your listening position & toggle back & forth on the phase; if you hear a difference in volume or sound micromove the speakers until you cannot readily tell the difference between in & out of phase.

I also own Martin Logan Arieus i,s and toeing them in about 2 inches seems to help.

I had a pair of Aerius speakers and found that it was very difficult to place them. It took several weeks of adjustments to achieve the best mix of accurate bass reproduction and maximum soundstage imaging. There are many factors involved in speaker placement, so my suggestion is to play around with the speakers until you achieve a sound with which you are happy. You will know when you get it right because these speakers will sound phenomenal. Good luck!

Well I think that as far as placement, toe in is the most important issue, unless your experience bass boomy ness, in which case it'll be much more difficult and you need to play around more. But I've found that with my Ascents, to get the best sound toe in the speakers so you can just barely see the inside of each speakers. Also 2 ft from the back wall should be fine for the aerius i
