am a mobile Dj and I needed to upgrade my PA system from passive to active system but I donât have much money to invest on it so I decided for something cheap and hope for good. I am very happy I choose right, The box pro dxs collection is awesome, too cheap for the sound it produces, the quality is amazing, the two down side of it is firstly the size is too big and secondly the sound output from the back of all the four that I have are not working but thatâs alright with me.
