What constitutes a mid- to large-sized room?

What happens, technically, in a small room with towers designed for large rooms? Would it create a big bass party?

No, they do not.
Bass waves are very long and require a fare amount of distance to unfold. Also the integration of the drive units tends to be better the further away you go, asuming your room does not have a lot of peaks and nulls. A big speaker like my pair requires at least 800 square feet and can unfold its acoustical power much better. With a huge dipol speaker the room is the case and they love space.
