Wow, thanks for the diagram. The bank shot analogy makes perfect sense, and I still haven’t mastered that and haven’t given up. I know my way around anything that has an engine, but get me working wood or sheetrock and it’s a disaster. If I really pushed for in ceiling or high wall mounted speakers, I’m sure my wife would cave as she also knows this is important to me, but there’s always compromise and she’s been agreeable with everything else and since the install would require hiring someone and money being tight right now, I figured modules would be the least intrusive, least expensive yet somewhat effective way to get atmos albeit with a bit of fiddling to get it right. Now it’s just a matter of finding ones that would fit atop my Polk towers.
