I love my speakers. But they seem to shine only when they play above a certain volume. At lower listening levels they sound bass anemic. Dont get me wrong, during the Episode 3 opening scene, I had the whole building structure shaking with the bass AND I HAVE NO SUBWOOFER
, so theres plenty to go around if you want.
The answer to your question is, if you like high SPL's (loud music and movies), the M60ti's are great. But if a majority of your listening is going to be at relatively low volume (background music or movies that dont need reference level SPL's for full effect) these might not be the speakers for you.
Edit: By way of comparison to Polk and Klipsch, I have gone back to the stores to listen to the upper end speakers by both (with my own source material) and have found them to sound muffled, as if they were playing behind a wall. Also, the Polk's seemed to have boomy bass in comparison to the Axiom's.
