I am so glad that you asked this question, because there are MANY people in this situation (including myself) where the listening area is against the back wall. You bring up a GREAT point in that DOLBY
recommends the SURROUND speakers almost to the side of the listener, and the REAR surround to the back. I agree that in this described room layout it seems that speakers mounted on the rear wall may be the easiest and most room friendly.
I would LOVE to hear input from you all, but this is the exact scenario I have been brain storming about. My best idea, and ultimate comprimise for this type of room layout is using BIPOLE as the surrounds. First of all, I think those surrounds should be designed like the Klipsch RS-62
, where the driver and tweeter is mounted on a steep angle on a triangle (or trapezoid) shaped box. That speaker should than be mounted AT LEAST 2 feet above the listener and placed very wide almost to the corner. The inside driver/tweeter would be at almost that side position that I talked about above. In addition, the other driver/tweeter would fire towards the side wall causing reflection. In theory that reflection would create a wider and more believable surround field. I think that is important, because THERE IS a large gap between the front LCR and these surround speakers. I recommend bipoles in this application because the speaker would be mouted on/near the back wall, and perhaps the reflection may cause the slightly out of phase effect where dipoles supposedly have their benifit. You also won't encounter the potential loss in lower freqency response that are somewhat inheriant with dual driver dipoles.
Notice that I did not recommend that tweeter-driver-tweeter surround design, because I think you may loose some of that side directionality (and wall reflection) that I was trying to create.Again, PLEASE comment on your thoughts of this idea for surround speakers in a back wall seated room layout.

I am currently using my homes in-wall speaker as my surround speakers in my current 5.1 set-up. I actually kind of like (and get a lot of compliments) from those old JBL in-walls. They came with my used house and are actually 4 feet above the listener. I plan on adding those bipoles in the configuartion I described above and think that my rear wall mounted in-walls would be perfect for my REAR SURROUND speakers when I jump to 7.1. I have posted pics of my room several posts back. Companys like Speakercraft make bipole in-walls.
