I'd be interested in hearing you views on the difference the 2nd 600 makes. I have a 4000 cubic room with a single 500 and really don't miss any bass. Of coarse I don't know what I don't know. I mean, I don't know what a 2nd 500 would sound like. But the single 500 is enough to crack drywall.

I am betting you won't get more bass, or better bass, maybe more even bass.

I bet with 2 600's you could start your own little earhquake though, that's always fun!
