This is absurd. It should be obvious that any speaker coil will respond to DC, just like a solenoid. Then the compliance or hold back of the speaker, will limit the deviation from zero. Let's move forward here.
Yes it is absurd. We are asked to believe that a speaker has no restoring force (except near the limits) and we are asked to suspend our understanding that there is a distinction to be drawn between a speaker responding to DC (as almost all do anyway) and a speaker 'working' down to DC (which would require either a sealed room or an infinitely large diaphragm). It is still unclear to me whether the person making these claims is confused or merely wishes to confuse us and his potential customers.

This is a rare case of, "If you can't join 'em, beat 'em!" We should cherish the moment.
The other absurd thing is to believe that the surround is in control of the restoring force, rather than the spider.

there can't really be "down to dc" sound...
if it doesn't have a non zero frequency it is not a wave and it does not propagate.

Tisros, what is happening here is sometimes called 'parsing' among engineers. That is to give a 'one up' by quibbling over a specific statement, written in real time, with its intent understandable to just about everyone, but criticized for its 'accuracy' by someone who just wants to look 'wiser' than another.
This sort of thing is often learned in Prep School.

OK, so that didn't take long. Ah well, I thought for a moment you might have finally found some snake oil that was even too much for you to support, but I was apparently wrong.
This is nut's! I thought a conventional speaker driver was quite a simple device and that the physics involved had been worked out long ago by the likes of Leak and those who went before him.
If a driver can cause such a degree of contention, it's no wonder we have so many successful snake oil salesmen.
Mind you I hear differences between copper and silver wire, mainly when carrying the signal from an MC cart, so I better get my coat

Again, snake oil exists, because the sound changes when you do 'dumb things' - and the normal explanation from the 'experts' is that it's all in your head.
Under those circumstances it's practically guaranteed that the 'good/bad oil' will constantly ooze and spread ...

All to the benefit of people like Russ Andrews.
Mind you I get a good laugh out of reading the comic he still insists on sending me.
These guys could show the alchemists of old a few things eh, how to turn a load of **** into a pile of gold - the modern way.

'Smart experts' will produce a cost effective product, or explain a technique, or evolve an overall mechanism that achieves the same effect as the costly snake oil - without insinuating that the consumer is brainless, because he can perceive an effect ...
I have contempt for those who confuse a lack of specific knowledge, with stupidity.
Saying that, i often have to deal with both as a marine engineer, the risks some people take with their own and others lives are criminal.
