Hi James,
It is a 3 way loudspeaker, still in development. The high/mid will be open baffle, the woofer will be closed cabinet. Since the filtering on the high/mid is basically a copy of another loudspeaker with the same units that sounds beyond excellent we have decided that we will continue to stick with this set up.
This is a project that will at least take half a year to finalize, probably more...
