>>Anyone who uses a sub with the 60's have any input? Is that needed in 2200 sq ft room?

2200 sq ft or 2200 cu ft ? Just checking...

For music I would say a sub is optional. I still often turn the sub off when listening to music. If your room really is 2200 sq ft, though, I would probably leave the sub turned on so the speakers don't have to work so hard.
