A question about trim rings around speaker drivers


I have seen over the years an increase in the use of decorative trim rings around speaker drivers that hIde the screws that hold the driver to the baffle, which makes them more attractive in the home environment. I don't have an issue with that, but I  learned a long time ago that at least twice a year, driver screws need to be tightened as they become loose from the vibration of movement. 

I was interested in a particular speaker by JBL that has black plastic trim rings, and I called two dealers as well as JBL to ask if these rings were easily removable by the consumer, and no one that I spoke with had the answer.

My question is: Do other members tighten their drivers on a regular basis, and are there members who have trim rings that they can't, or haven't tried to remove? I would be surprised if this was something that JBL or other manufacturers had not considered.

I would guess it depends on the screw thread, the material, and how much they were tightened in the first place.  

With older speakers it's prudent to rotate the woofers 180 degrees every few years to offset the pull of gravity on the suspension, but never once have I encountered loose woofer screws.
