However anyone wants to define the various conditions, my experience is that:
* when the electrical part of a driver is damaged, when that driver is gently pushed in by hand, there is a scratchy feeling, but when power is applied to it it may still play, but will rattle.
OR
*when the electrical part of a driver is damaged, sometimes it will not play, but if the volume is turned up to a certain point or a bass heavy passage is played that driver will "unlock" and begin playing.
I have witnessed these conditions many times. I have very seldom had a driver not play at all due to electrical damage. This is my experience, over 25+ years. We can continue to debate what the various conditions are, or how they are labeled, but none of that has any bearing on the topic. I am perfectly aware of how a speaker operates, and have been so for that 25+ years. Thank you for the refresher course.
vmaxnc - I'm not trying to **** you off. But for someone in the field for 25 years you sometimes say things that don't make sense. A rubbing voice coil will definitely cause a speaker not to play correctly though it will reproduce sound. If a speaker sounds bad, then becomes "unstuck" it probably has an intermittent electrical problem that goes away temporarily when the electrical signal is strong enough. I have seen this happen when the tinsel leads are partially damaged.
If your sub generates hum then the problem is in the amplifier or the wiring that feeds it. Test it by hooking up the sub driver directly to another amplifier (after disconnecting the driver from the sub amp).

We're saying the same thing. Not sure what the disconnect (pun intended) is.
I'll get back into the sub next week, and probably drag out my other M&K as well to see what it does.
