I have an old set of AR5's from 1969. One of the
speakers makes a raspy/distorted noise on playback of hi frequency
sounds. I have noticed that at the base of the paper cone there is a
connective seal, like glue. On the tweeter in question there are some
open gaps in the glue. Could this cause the distortion? Can I glue
this area to help secure the cone and reduce distortion?
