Vibrating Mid Range Speaker

[Coach P.]

I own a pair of SDA 2A's. Most recently, I am getting noticeable and unflattering vibration from only one of my two mid-range drivers in the right speaker.

Do I need a new driver? If so, what is the best way/least expensive way to obtain a new one?

If I don't need a new driver, what do I do to solve the problem?

It sounds like it's worn out.Polk has replacement drivers.
I would replace both drivers in both speakers,if you plan on keeping them for awhile.Fresh new drivers......cool.

:) Thanks Mantis. I appreciate the prompt feedback. I've contacted Polk and will have a new driver soon.
