Thanks for the reactions…
@BriHar - I already read that the KRK’s are a lot more “boomy” or “boxy” (in a bit negative sense) and a bit too colored, but that’s for the older (G2) line. The newer G3 line seems to have some improvements, but the “boomy” aspect is still present. The Behringers are prortretaid as “a bit harsh”, but have a more flat (read less colored) frequency response. After reading several forums and user experiences I kind of lean towards the Behringer.
@iBM - I will certainly take an look at the Eris 5. First reviews seems very promising indeed. At the other hand - I have also read remarks that the Eris 5’s are very similiar to the KRK Rokit series. Of course that can be very subjective.
Anyway - thanks for both reactions. I still have some days before I will make my final deceision. Of course none of the monitors in this price class will be perfect, but this will help to get the best for that small amount of money that’s available…
