After considerable research I decided to go with the Axiom towers. I first bought a pair of M40ti and found it lacking a bid in the upper middle frequency compared to my old PolkAudio SDA compacts. Otherwise, it outperformed the Polks. Not satisfied I then upgraded to the M60ti which produced my missing upper middle sound I found lacking in the M40tis. Overall I am happy with the sound except that I noticed that I now have a listner fatigue after 15 minuites of listening at normal listening level in my 18x14x8.5 room with me sitting roughly 12 feet from the speakers slightly toe-in. Could this be related to the resistor adjustment phenomemon posted in the other post?

Thanks.
