I'm sure this question has been asked in the past but I could not find the answer anywhere.

I'm building a new home and the wife is allowing me to have a man cave the dimensions of the room are 20.1 (L) x 14 (W) 8.5 (H). I am looking at getting M80s for fronts and vp180s for center. Will these speakers be over kill for the room? Or should I look at getting the m60s and vp150s?

I plan to use the room for listening to music, watching TV on a wall mounted 46" with a viewing distance of about 8'.
Any suggestions would be appreciated.
