Drivers and how to clean them: Notes from ScanSpeak

Do you rotate larger drivers to mitigate the effects of gravity? I'm my 40 years of playing bass in many bands, I did this on a regular basis as did the sound companies I worked with. I never blew a driver, unlike a lot of other bassist I knew.

I had a 2004 Porsche Cayenne with a subwoofer under the spare tire. There was a leak (they never could find) that filled the space with water. 
In spite of the “blub-blub” bass, the driver was extremely clean 😜😂😂😂

I take all my speakers into the shower for an intimate cleaning session 😎

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.

Compressed air works great: 2 cans for $10.00 at Best Buy.
