B&W 702s or Revel F208s

The mirror method will get the primary reflection, which is the more important of reflections to contend with.  The area of the wall adjacent to the speaker will have reflections that will likely hit other points of the room well before it hits the listening spot, much due to the very wide reflection angle. In any case, you've targeted the first reflection that you needed to.

If you place the speaker closer than five feed to your listening spot, the ability for driver integration. I would keep a length of 6ft or more from the speaker to the listening spot, which is something you've already done. These aren't near field and don't pretend to be.

Okay! It seems like I can “fix” everything except a couple of things that I am not sure of, so here we go:

1 - What is the minimum “allowed” distance to the side wall (from the side of speaker panel)?

2 - What is the minimum distance speaker to speaker (from drivers)?

Again, everything else can be changed (distance to back wall, from listening position, and such)

BTW - I am listening to the new Acoustic album of Eva Cassidy, and it sounds amazing! Incredible soundstage, clarity, and air. Very natural!

In general, the speakers can range from 6ft-10ft, center to center. Going wide may create an overly diffuse sound that don't provide a good center fill. Narrower would hinder the sound stage overall and the ability to place across. There isn't a minimum from a side wall, but ideally one would want 3ft from the center to side wall to delay the first reflection arrival to listener. This allows the our hearing to discern the direct radiation from the reflection and maintain them as two events. Adding absorption or diffusion will reduce the reflection amplitude, which you mentioned you have some form of such.

Revel speakers have a way of producing a even handed, neutral, and relaxed sound that is engaging while still providing good dynamics, bath macro and micro. They don't have the immediacy that some speakers provide, but I find their balance much more enjoyable over a wider range of genres than most I've listened to. You simply stop listening to speakers and enjoy the music.
