I have had a pair of Behringer MS20 monitors speakers. I’ve had them for a about 6 months or so. They have a fairly thin, but detailed sound for the price point. One thing with them is a good mix sounds VERY good, while a bad mix, or a badly encoded mp3, sounds woeful. I would ot call them mega accurate, but they do seem to show up bad mixes very well.
Note that I dont use these for writing music on, mainly just general music listening.. in fact more as a high end set of 2:1 PC speakers than anything, which they are great for.
I got bored late last year and voided the warranty and opened them up, so here are some pictures of what the insides look like:
