Sagging Voice Coils?


I was just reading a thread on AA where someone mentioned that one should rotate bass drivers to prevent the voice coils from sagging. It sounds like a problem for geriatric speakers, but is there any truth to this?

Rrog, yes I disagreed with your premise, but did not make any comments about you. That is what an ad hominem argument is, when you don't agree with a person's premise, you attack the person, not the idea. No, I never said anything about you at all; I just disagreed with your conclusion. You took it to the personal level. And I believe that I was quite respectful in my disagreement.

Again, we can agree to disagree, I will let the posts speak to our relative character.
And as far as there being an issue with my calling it an urban legend, I did so in the second post in this thread, well before you ever posted, and simply repeated what I had already said. I couldn't be disagreeing with you before you posted, now could I? There has to be just a saucerful of logic between the ad hominem musings.
These were built in the '90s, and they knew about the sag problem then. [http://www.roger-russell.com/xl1w.htm]
You might notice; that article, and it's accompanying remedies, addresses downward facing woofers only(as in some subwoofers). Many of which have heavy cones and/or long excursion(some double) coils. The effect of that type of sag would displace the voice coil, from it's centered/at rest position.
