Two years ago, I compared the Rti8 and Rti10 to some Infinity Alpha 40's, and the Polks sounded a bit lifeless in comparison and muddy in the midrange. I've heard the m60 and m22 and can clearly say that the Axioms sound much cleaner. The metal tweeter on the Axioms puts out much more detail than the soft domes on the Rti series.
