Genelec 8260A, Unbelievable Monitors

Take a look at theĀ free field response of new Genelec 8260 active studio monitors here, http://www.genelec.fi/documents/datasheets/DS8260A.pdf. I have not seen such a linear free field response before, and it is from 29 Hz to 21Khz plus minus one desible! Some manufacturers are talking about ultra linear, well, I think this could be it, if any.
