I use the behringer ms 40 as computer speakers. I am really amazed by its soundstaging given my proximity to the speakers. You get a precise but smaller soundstage. frequency response, to my ears, is just fine and I find instruments and vocals natural enough. This is a very good buy depending on what you use it for. As computer speakers, I think they are the best you can get for its price range. I also tried it in my home audio and theater setup. I compared it to my usher x-719. Mids were good, highs were ok, bass was bad. But remember this is in comparison to a bookshelf that really goes low.
If you listen nearfield and want a cheap and amp free setup that sounds good as well, get the behringer. But if you want a regular audio setup a good buy is the wharfedale 9.1. However, you need an amp for this.
