I have a room that is 15ft by 15ft with the ceiling probably around 12 to 15 ft high. I currently have a pair of bookshelf Mirage M290's on stands, which are great, but I would like to go to a (possibly) floor standing model. I am not sure which of the three speakers models would be best for me. The models I'm thinking about are the M40ti's, the M50ti's and the M22ti's. I will not be using a sub. Should I even consider the M22ti's? I am using a 60 watt per channel Onkyo receiver for amplification. I listen to 95% music and 5% dvd/movies. I listen to mainly contemporary folk, classical, with some progressive rock mixed in. Just from what I have read so far, the M40 ti's sound like a good choice, but I'm not sure. Your advice would be appreciated. Thanks.
