The subwoofer itself is amazing, loud, goes low… Everything is great except for the limiter, if you like to push the sub to its max the Limiter tends to kick in a lot, the problem is that the limiter lowers the volume of the sub by about 50% for a few seconds when you hit it. Another problem is the cooling fan, the fan is always on and is pretty loud, but in most cases when music is playing you cant hear it.
