Once you use them you are kind of stuck. Your ear gets use to them and you mix to them. You can go to several different studios and you can mix easily. The idea is that the sound that comes out of the speakers goes directly to your ears and not reflexive sound. I have 1030a and they are small but I can mix in bad acoustic rooms and still have a great reference. You can plug any speaker of theirs into any of their sub woofers and have the same reference sound. So the use of Genelec has been growing and have become the standard. Sadly they aren't cheap but they are worth it. Mine are almost 20 years old and they still are great.
