OP, people have different needs. Space being one of them
Ideally, you wouldn't put put small speaker in a large room, nor vice versa
I happen to be blessed/cursed with a very large room by most enthusiasts standards. I have tried several dual sub setups, but have yet to find any of them blending seamlessly, and although I do not believe that bass loads in a room in same plane as the mid/highs, I am in the process of trying Emerald Physics 2.8s. Fingers crossed
