These monitors are very pleasant not only to work on but also to listen to music. The overall frequency response is quite flat. As you can expect from a speaker of this size, low-end is not it's strong suit, instead the mid-range is very revealing and forward sounding and the higher frequencies aren't at all harsh. If you are looking for monitors to mix on, I would definitely recommend these. I've only had them for a few days and am really enjoying them. The bass and treble controls allow for greater flexibility in their use. Set them up, measure their response in your room, then EQ them with Sonarworks or REW, and you're quickly in business.
