if you have a look at my room, you will see that it's quite small - around 1500 cu. ft. plus an open doorway to the kitchen = 3000 cu.ft. - and i sit about 6-7 ft from the front speakers.
when i play some demanding movie at Reference Level, the front speakers need around 300 Watts/ch.

How did you get to this number?

Physics dictates that it is distance from the sound source that determines the power required.
