Yes, but a church/school scenario is totally different from Steve Deckert's paper, where there is just one listening sweet spot. Steve's method mainly asks for diffusors in two locations, which is a fantastic money saver (especially for a nomad like me).
So, the real question is, do you think Steve's method is flawed? If so, what would you do to make it work? You can suggest your own products if that's allowed--I have no objection to hear your opinion based on what you sell...
Yes, a church/school scenario is completely different and I use completely different products when treating it. My point was that it is not based on the setup, but the room. Now am I oversimplifying? A bit.
Ideally every 90 degree angle in the room would be treated. That is not typical of most of our customers. So if you were faced into the corner, I would err to that corner for soundstage hieght. For example, with our Roompack, I would put a seam in every corner, and a corner in every ceiling corner as usual. Instead of putting the Echos on the front and side wall or the front and rear wall, I would put both Echos about a foot or so out from the ceiling corner that you are facing.
However, 90% of the improvement in this room will be because of the Seams and Corners, not the Echos. The Echos have always been a fine tuning device, while the Corners and Seams are the workhorses.
I think most room treatment placement is flawed, but there are notable exceptions. But treating where the "rays" of sound hit is just not effective in my opinion.
