Getting a backer box of any size between all that is an exercise in futility I'm afraid.
I'll be interested to see some actual installation recommendations. I'm anxious to see what Dolby will say.
Do you have an idea on what depth you can accommodate reasonably ? Building a normal speaker (not in wall) is probably the easiest to design, build and install. It's also got predictable performance, so if you are using a DIY design or something that's a bonus.
I've seen some stuff like this: http://www.parts-express.com/eminenc...-x-90--290-713
Bi-Radial Horn 90 x 90 :
Specifications: • Throat diameter: 1" • Driver mounting: 1-3/8"-18 TPI • Nominal coverage: 90° horizontal x 90° vertical • Lowest recommended crossover: 1,300 Hz • Dimensions: 5-15/16" H x 5-15/16" W x 4-1/4" D • Cutout dimensions: 4-1/8" H x 4-1/8" W.
That seems like a pretty good option. Throw in any old 5" or 6" driver like a dayton or eminence or whatever, and tune it for high efficiency by intentionally sacrificing instead the LF extension, and cross it over to something like a DNA-205 (like in the FUSION 8/6)
I guess actually you could just take the FUSION 6, swap the EOS waveguide for the 90x90 waveguide, and then mod the box to be wider, taller and less deep. That's an easy option. It would timber match and integrate really well with the rest of your speaker set up, and provide the atmos specific specs required. Unless I don't understand something about ATMOS, which is entirely possible ... lol
The question I had was the 90 degree dispersion is important in both directions ? Or just one ?
