I listened to the the Klipsch F-3 and the rest of that series. The F-3 was BY FAR the best of the bunch. Also listened to the upmarket Klipsch bookshelf RB-75($600 each)...horn and one 8 inch copper colored woofer with port. While the F-3 was good, the RB-75 was really fine. BUT, The sound is very "in your face & in the middle of the band". This was great for hard rock (Creed) but for the other music I tried (Vivaldi & Barb Streisand) it was too strong but still sounded good. I purchased Athena AS-F2 towers which have a very pleasant brightish airy high end with good solid midrange and bass. Very transparent. They can rock hard but can go easy and grand too. Now, I have not heard the M60ti or any other Axiom speaker but if you like HARD ROCK, Klipsch is your speaker. I have to say that I am skeptical that the 5" midrange of the M60ti can push out serious sound in hard rock mode (60% of my music). Therefore, I'm leaning toward the M50ti for a den setup.

OH!!! GET A WARM AMP FOR THOSE KLIPSCH SPEAKERS!!!
