SOUNDS

We hear much bass on its register of all sub jusquaux severe acute crystalline (thank you tweeter) However, be careful not too push. one has the feeling of an enormous sound pressure as pied.certains can find him can be a certain coolness as it is a very neutral speaker without coloration that refund in my opinion the sound of the bass itself, but good n ' This is not a high quality?

OVERALL OPINION

I use it for 6 months I was in rooms with 3concerts medium and it is exactly what I prefer is the reserve power that has been the "face" of the speaker negative point c Is the weight of the beast!!
