Zeal:
The S-2EX's use a different concentric driver array than the 3's. In there case, both John and I agreed that the beryllium-driver based concentric driver combo sounded the sweetest just above axis. We therefore positioned them raked slightly forward. We also toed them out so that they fire well to the sides of the listener. In my room, this is a very good way to set them up. The farther way from the side walls the better. It really opens up the whole sound stage.
