Toe-In or Toe-Out

stereo5, you are correct, with the age the ear goes bad with time, and also the open room is another issue.  Thank you

oldhvymec, Thank you for your help.  Have you a dB and laser model device to suggest me ?  I am now writing you from my computer situated in the back left cornerof my open space room, all curtains are now closed, and the sound is better than on my listening chair, it is realy weird, isn't it ?  Thank's again.

Mine were freebies from work. They were a writing pen and a laser pointer combo. Worked great for me. The db meter, no need to get fancy. If your going to use a phone or something like that just use a stand so you're not part of the equation and use a painter tape reference on the floor with alignment marks for clocking the pickup mic the same direction the same time. I used a pair of Galaxy S3s that were both retired a long time ago. You could even pair them and WiFi the info back to a 3rd phone or laptop..

I'm frugal.. LOL Works sweet as can be.. Cost? 10 minutes of learning Doggle or VPN or Tethering or LOL what ever you want to use for FREE. You can just use one too. tape marks on the floor like I said..

Have fun...

Merry Christmas come to think of it..

Crossing just in front of your head or just behind your head is still toe-in not toe-out. I have never heard any loudspeaker in the toe-out position. 

oldhvymec, I check my right speaker, it was 11/2 inche to far from the right.  I check the front wall, 26 inches, it was OK for both.  I have tried, near listeng field, but I prefer far listening. in my 17x22 feet x 8 h.  My speakers are 61 inches centre to centre.  My ear, on my chair are 131 inches from centre of the speakers.  And it is now better.  How is important the positionning !  Thank you.  Not easy in getting old ...
