Bub, I think that is a lot of cubic feet of air to have to move around with speakers of that size - IF volume is a concern. Your listening habits are meaningful here. As others have said, let your ears be the judge. If I had to have small, stand-alone speakers in a room, I would not hesitate to get the M3's. And you'll probably be amazed at how much a sub will add to your listening enjoyment. And the M22's are only $125 more. And it's not MY money
