i think you should go for the family room,with the size of your entertainment center and floor-standers,front and rear,you would be hard pressed to get it set up in a 10x10 room,although it could be done,personally i think too much would be lost or wasted!i'm in a room in the basement,'bout 8x12,with stand mounted speakers,and not alot of power(just quality) my biggest complaint is with the sub,it sounds great,but, those loooong bass waves don't wanna develop until the top of the stairs!(cool neighbors),my ideal setup would be in the garage with the sub in the basement and use the stairway for the bass port it wants to be
