Another consideration is speakers that are designed for placement very close to the wall or even the corners that will give you more room in the room for your listening space.
I moved from a 26x18 room to a 11x14 room and found the larger system would just not work in the smaller room so I went to smaller stand mount monitors ( Sonus Fabers) that worked well with some room treatment. after a year I got a set of AudioNote ANE's and they sat in the corners and gave me the bass back I was missing from the monitors and with the room treatment sounded great. I had an open double door behind my chair so I was able to get back further from the speakers.
