Do you think they are worth repairing?

Pioneer are not exactly known for their high end speakers.

Might be easier/cheaper/faster to get a brand new set of round ones and make square spacers. Many speakers come this way these days
You can use butyl too instead of making wood spacers. Really depends of the overall shape of that original speaker location.

As square speakers are very hard to source, I have been unable to find replacements.

Does anyone know of a company that will refurbish/restore vintage Pioneer car speakers?

Many thanks.
