With a smaller room, you may be better going with just one sub, like the 350, 2 Qs8's instead of 4 Qs4's. You could always prewire the back of the room and when your budget allows get a 6.1 or 7.1 setup. Not much comes out of the rear channels anyway for movies. There have been many people that have purchased the 125's but then later wish they would have upgraded to a bigger sub. Just because your room is smaller, doesn't mean you could not get some 50's or 60's floorstanding. However, I'm sure the 22's would be fine with a sub. My room is 30ft x 31ft and one EP500 sub is fine.
