haha, thought this thread was about QS8 placement!
Having now heard both the M22ti(s) and the M80's, I can say that going with the M60's is a no-brainer (as the owner of the company states that the 80's are just like the 60's but can play louder, I'll trust him).
If you are leaning towards the upgrade - fear not - you'll be completely satisfied. The highs are clearer (can you believe it) and the low end blends in/slopes much better with a sub. You'll want to cross your sub at around 60Hz, but of course feel free to experiment with your room.
Enjoy!
