I just buy one month ago and I can say that it really rocks! I used two on one speaker stand led to the scene to use as back, and it's very nice. Well, it must be said, in low yield is really not very far! but I return mackie another colleague of scene that reinforces the lack ... I had also amico 100 back, and although the extruded are much better.
150 watts x 2 is a good compromise! The price that we can find approx. Occas 200 euro coin is very good ... Of + they can be used in restaurant or voice sound better!
