For the price, I find these speakers really well.
At low, no problems, however, at the midrange and treble on some songs, they should be reduced by using the mixer in order to have a good sound.
However, the value is good!
I'm using these speakers for some time, never had a problem with!
The only downside is the power that I think does not really 250W.
Finally, for small budget, it is the ideal forum.
