Zenith Fieldcoil Speaker Repair

We specialize in Vintage speaker repairs. It is difficult to repair many older speakers because the parts are no longer available. We often have to use our special Spex magic to modify existing parts so the repairs happen but abracadabra and all that jazz.

Here are “before” and “after” photos of an old Zenith speaker recone we just completed. In case you don’t know, a fieldcoil is a semi-permanent magnet in which the field is produced by an electromagnet rather than by a permanent magnet. It was often used in juke boxes and organs, but is not as popular due to the invention of the permanent alnico or ceramic and now neo magnets.

Just think… if we can succeed on these older speakers, we can perform our magic on your speakers too.
