has anyone on here tried building these? I'm considering it in the future but would like to see some build pics or at least get some verification that they work well/ are worth building first.

does the slot throat on the front of the drivers actually do anything? would have thought this design would work better if you turned the speakers round sothe faced each other and angled the baffles slightly so the central chamber flares toward the mouth.
