Wilson Audio sophia 3 or Watt Puppy 6

I think that all responders to speaker threads should list the dimensions of the rooms they have. i am chewing on getting some sophia 2s or 3s and see watt/puppies that might be barely affordable if i stretch. but there is no point in stretching if it results in a speaker that is too much for my 5 sided( opens into a hallway with small room on the other side) 18x13x8 room.
Secondly new speakers usually create to me a need to at least change old cabling to find tune the change- maybe not doing this is a source of disappointment also.
Third different people hear far differently than a lot of people realize

watt/puppy 6 is a very old design with very old drivers. sophia 3 will eat it alive - not even close

Would anyone care to share their wilson sophia or watt puppy appointed room's dimensions? What do you consider to be to big or too small? i still beleive getting the room/speaker right is the most important thing to long term satisfaction that lasts beyound the honeymoon period. i just bought some sophia 1s for a 18x13x8 unsealed room. watt puppies were tempting but i worried the room would be too small..
