How far away from your speakers are you?

Magnepans: 4' from back wall, 3' from side walls, 5' from each other, toed in 15 degrees, 20' from my listening position. Thinking of adding a Magnepan DWM bass panel, separately amped (the bass panel has stereo inputs).  Does anyone use the DWM?  With what results, please?

Once I read that a good way to find a place to put your speakers is to put one of the speakers in the chair where you sit (if they are small enough) and to move around the room with music going in the chair and find a spot where the music sounds balanced. Put one of the speakers in that spot. Repeat the process for the other speaker and put the other speaker in that second spot. This procedure also works with small sub-woofers to give balanced bass. Alternatively some people like to put sub-woofers in the corner. That often gives more output, but there is also a level control on powered sub-woofers.
Other recommendations are given by the manufacturers. You could try that, too. They often suggest things like a triangle shape, and various amounts of toe-in and distances, such as the rule of thirds.
I have recently experimented with four Magnepan 1.7 speakers by putting two on one end of the room and the other two facing in the same direction about halfway along the room near the walls. It really gives a big image. The key is experimentation.

I use vandersteen model 5s.  I sit about 10 ft distant.

With my maggie 1.7s I have them 6.5’ apart, center to center (5' edge to edge) with the tweeter ribbons to the outside. They are exactly 41.5" from inside back edge of speaker to the wall behind and 42.5" from outside back edge of speaker to the wall behind, so very slight toe in. The rt. speaker is 3’ from side wall and left speaker is open to the dinning room. The audio room is 14’ x 27’ plus 11’ x 14’ open dinning on the left. Listening distance is 8.5’ from the center of ea. speaker, so it works out very close to the 120% ratio. I have a well dampened room with acoustic drapes across the wall behind the speakers. As set up, the image stays tight and true regardless of standing sitting or in or out of the center sweet spot, but if the toe in is changed even by I/4" the off axis imaging diminishes. I’ve tried changing their placement a dozen different ways but nothing sounds as good as exactly the way it is....Jim

Thanks Larry5729 I rechecked with the Ballad of a Runaway Horse by Jennifer Warnes and felt placement and imaging good but had to mess anyway. 

I sit 9’ from speakers.
