At that price, I think the 60's are the way to go...The only things the Monitor 11's have is a lot of bass...and many will argue it's not the tightest, most accurate bass either.
I'm not a big fan of Paradigm's larger tower speakers, but you might like them.
The 60's are a far superior speaker to the 11's though, unless you are booming bass head, I can't see you picking the 11's over the 60's.

What else have you listened to? Lots of other speaker companies out there...don't limit yourself to just Paradigm offerings.
