That is a good outline and I've seen designs like this. Some designs have the speaker soffit across the corner of the room. Is there any advantage to the design I showed above where there is a larger space behind the speakers and front wall to add additional treatment. My idea was to create a larger space to treat my most troublesome room modes.
You could do that, yes. But just to clarify: the soffits don't go across the corners. They are a bit more towards the center of the wall. In other words, if you draw a line out from the corner at 45°, the speakers are NOT on that line: they are considerably closer to the mid-line of the room. If you did have them "in the corner", then your speakers would be equidistant from the front wall and the side wall, which is not a good thing. Those distances should be different.

In order to improve the angle and create a true RFZ, I usually add a second section to the outer part of the soffit front baffle (the part that meets the side wall), at a larger angle, to "wrap it around the mix position" a bit more. You can see that in this thread: http://www.johnlsayers.com/phpBB2/viewt ... =2&t=20471 You can see the dividing line where the outer section is angled more than the inner section. In this case, the baffle is tilted at forward at a slight angle as well, which is the reason why that line angles diagonally: in your case, it would rise vertically.
Is this end of the room an appropriate place to have more treatment, or is that really for the rear of the room. I have a long room, so I can easily give up some space on the console end.
The rear wall is pretty much always the most problematic, in practically all rooms. You'll need lots of treatment on the rear wall, regardless, but treating the front wall can also help.
