So if all the jbl's are doing is applying an EQ curve - could this not be replicated using any other system?

Like this one?

I'm sure the jbl's are great, but are they worth buying just to take advantage of an eq curve that could be achieved through running a piece of software and overlaying an EQ curve?

Am really in two minds about whether to sell my mackies or not. Am already worried about the cost of shipping all my kit over to argie, and it might be cheaper to sell them and buy the jbls over there if they really are that great...

Appreciate your input stevio
