In fact I did but your description was a bit ambiguous. But that is not the point.
Much of the low impedance occurred with the bass drivers well below the crossover frequency. I suspect the bass drivers are very similar if not the same drivers.
In all likelihood the measurements would in fact look similar when it comes to impedance and almost certainly it will dip below the nominal 4 ohm rating.
Didn’t mean to debate the point with you and just wanted to pass on some important considerations as you look for a new amp.
