"the notch at 160Hz seems most likely to be an underdamped column resonance"About the only way you can get a notch like that is via an out of phase reflection. I've seen it claimed that the problem was caused by a ground reflection to the mic, but that doesn't wash if the measurement was done in an anechoic chamber. The impedance chart is classic bass reflex with a 50Hz fb, it doesn't even resemble an underdamped TL, let alone a stuffed TL, which has a single peak at fp. A quarter-wavelength driver to internal boundary reflection is most likely, being a tower I guess there could be a 1.7 foot internal path that wasn't rendered non-reflective. If they did fix it I've never seen a new measurement.
