I don't know if 18-20 inches would be enough space for a false wall, and what do I do with my front wides? if they are going to be outside of the false wall, what is the main benefit? I'm just asking because I really don't know. I really appreciate the help.
For one thing, an acoustically transparent screen allows you to place the speakers directly behind the material, just like a commercial theater. This locks the picture with the sound rather than having the sound of the center come from below the action or the left and rights off to the sides of the screen. It's the best thing you can possibly do as it is the premium speaker setup in a theater.
Given that, using the RC-70's behind the screen... you may be pushing things a bit given their large size. If you sell your Energy's and go with Triad Silver LCR in-walls or in-room's behind an AT screen... you could easily
pull it off (someone made a 14" deep false wall -- total depth of 12" decking with stud framing and screen frame mounting standoffs -- and used larger Triad Gold LCR in-room's and two medium subs behind the screen with no problem - see image above). If the cost of the Triad's happen to fall outside your budget (I don't know the latest retail price-- check the Triad speaker thread or contact AVS's sales staff for a quote), you could go with the Def Techs I mentioned.
The Triads would definitely be a big step up in sound quality.
You would size your screen up to your seating distance... I doubt it would cover the entire width of your room. This is a handy calculator for 16x9 screens. http://myhometheater.homestead.com/v...alculator.html
Then you would place front wide side surrounds on the side walls. They usually sit a little bit between the traditional side surrounds (perhaps slightly closer to the screen wall than the side surrounds) and your front screen wall speakers and are angled to fire towards your primary listening space. They fill in the sonic gap between those two speaker positions.
Again, we should know more precise speaker locations for Atmos fairly soon.
