Again that’s fair. But if you’re referring to me, a can tell I have a lot of experience with large(and small) rooms. Mine is open concept with the listening room being 16x24 with a 12’ vault on the right side(center between kitchen and LR), kitchen is almost the same size, but the LR is sunken 1’, opens into a foyer and another bedroom and also has a hall way. Also concrete slab. Definitely huge. I’ve tried a number of pieces over the years, and Ime, in this house, it takes a lot of subwoofage. And I don’t consider myself a crazy basshead either, but do have a true appreciation for full range playback.
