I have KRK Rokit 5s. Luckily, I got them on sale at Guitar Center for ~$250 total! Let's just say they sound incredible! My mixing got better instantly from the M-Audios I had before. Frequency response is 53Hz - 20kHz so you either would need a sub or good headphones to hear the very low end... if you need
to. I swear by these and considered getting the Rokit 6s but they were really too much for my home studio. The 5s get PLENTY LOUD! Great investment. Best ones I found for the price range. They are fairly balanced and I have never felt they were hyped up in any frequency range.
KRK recently made Rokit 10s!!! OMG they are huge and impractical for a home studio (imo)! Unless you want
to go def and piss off your neighbors.
