You really don't need to worry about the size of the speakers compared to the size of the room. Just get the biggest/best speakers you can afford and go with that. There really is no such thing as a speaker that is too big but there really is such a thing as a speaker that is too small.
The Sony speakers will suck in rooms of all different sizes.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
