The AC Epicenter and the BX-10 are the same device, the BX-10 having more features though. Others like the PG BassCube simply add bass.Is there really any difference on the audicomtrol, sound stream, PA, or Hitron, if im not mistaken i have used all 3 and i taught all o them where the same, only difference in some where the color and well the controller, but i toght all sounde the same, but i might be wrong.
