Do you rotate larger drivers to mitigate the effects of gravity?


Generally not something the average audiophile should do! :)  The size of professional drivers is so different from what I have in my home. I have a single 15" subwoofer, and everything else is 7" or smaller. I'm sure they will outlast me. :)
I have never rotated drivers, but, it is probably a good idea to do it.  I know that Lowther driver owners do this regularly because the gap for the voice coil on Lowther drivers is extremely narrow and the slightest sag will result in scraping.
Thanks Eric,

 I’ve been having work done on the house and I’m sure one of my speakers got attacked by drywall dust. I was waiting for the construction to be finished before I went in to see the damage .
