I am working w/ the speaker on this unit that does work but it has some vibration at higher frequencies.

You can hear it pretty much all the time but really bad with music. Lower voice radio shows sound better.

I'm thinking the coil is vibrating or something down in that area.

Currently trying to see if I can center it better.

Thinking that just swapping to a perm mag setup may just be the best bet.

What is needed to do this if I end up down that path?
