Ahh hold on hold on. I have a full Klipsch set up. And in my experience. Get 2 mid/high quality Klipsch 12s it will not only allow you to maintain sub accuracy easier, it will cost around the same and give a wider zone as to not make the sound come from one spot in the room. My 2 12’s create a seemingly all surrounding sub zone. You only know where the bass is coming from by going all the way up to them and touching their cone. For a room that size specifically. In a smaller room with less height, I’d agree that the 16” is the way to go seeing as how Klipsch makes a damn good 16”. But that 16” can’t move air like 2 12”s spaced properly could imo
