I have a Tyros 2 as well. I played with one Bose Compact for a year and was never quite happy until I got the second one.

I guess it all depends on the type music, venues, and how much volume you need. I think the Bose are a great for moderate volumes. If you need to put out super-crazzy-ear spiting-chest pounding volume, maybe consider something else.

Good luck!
