I've looked at several reviews on these speakers, and move gave them great ratings, Anandtech liked them, and several other places. I did a search on 'review benwin bw2000' on google and I have yet to find a negative review on them. I also have some at home, and for the $20, they are awesome, they are as good as if not a little better than my Altec Lansing 4.51s that cost me about $120 a few years ago.
Sub is a little weak though, I'll concede that.
