If you're interested in buying monitors for production i'd consider looking for what else is available. IMO, i believe from listening to a large amount of monitors, you're paying an extra $100 for the yellow cone in the middle that's incredibly well marketed.. Where you can find something of similar quality for much less.
I find KRKs to be too coloured in there sound for my liking.. If you're after some monitors more for listening to others music as opposed purely for production they are not a bad option though.
