Welcome Jac,

Your room could very well do the M80s,11 feet away should be fine I sit 13 feet away from mine.I have them in a room that is 15x20 and they sound great.You already have a reciever that can handle a 4 ohm load so that is a none issue.

If the extra money for the 80s is ok then I would say what the heck go for it you will not regret it.
