Pay attention bill. The JBL 2123H 8 ohm is only 4.2 ohm and the JBL 2123J 16 ohm is only 8.7 ohm, remember? They are really cool anyway. Just look at their frequency response curve... is flat! Do they have extremely rare magnets ??? ...or what is it. Maybe just to many years of "secret" practice, way distant from public view.
