I have this issue my room is a little bigger, 20 ft ceilings. The whole ad drape thing and room treatment made me laugh. I have huge picture widows, fireplaces, and columns in my great room. I can imagine my wife listening to me talk about adding drapes … I would be sleeping in the car. I am waiting for ART in DIRAC to mature to see if this works with larger room sizes. Otherwise, it is impossible. I have tried klipsch horns… They blare in a room that size. I think we had JBL. I grew up in the movie theater industry, and they used to have these huge JBL under the curtains for sub (started with esrthquake) for movie buffs. They also had like kbl speakers the same size. My wife, again, wouldn’t budge. Gl on your solution hunting.
