  • "You've got to use Four\

    As reviewed by DJ Ron on 8/2/2007

    These speakers sound great but you have to use four or more to get the quality bass out of them (coupling effect). Using two is a waste of time if you require deep bass at loud volumes (you won't get it). They are quite expensive and you will pay a hefty price for four or more. True Bose lovers will shell out the cash.
