Damping Factor - Interesting article

Considering there are no speakers flat to 0.5db without equalization, let alone 0.1db, are we certain that a super high DF is going to result in the best on and off axis frequency response?

What is likely to product worse cone breakup, a high DF or a low DF?

According to this article DF=100 produces about 0.5dB variations typically, while DF=200 reduces it to 0.1dB. DF above 200 is inaudible.

What is likely to product worse cone breakup, a high DF or a low DF?

To my understanding, cone breakup has nothing to do with the amplifier.

High damping factor directly into a driver as opposed to electrical dampening, can make high frequency ringing of the cone worse exacerbating some breakup modes. From a high level model, high DF can be like holding the voice coil stiff while the cone flexes. With low DF, the voice coil is not stationary and moves with the flex, and the increased resistance of the lower DF dissipates the energy of the motion. Very high level, almost like adding a resistor to a snubber.

I should clarify, I am not saying a huge improvement, but the low DF will in many cases be better.

That's an interesting idea- but I suspect one that has not seen a lot of study.
