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.

Infocomm 2015 was much bigger and busier than ever.  The sights and sounds can be overwhelming. Lots of amazing signage and very very large screen video.

The Audio Pavilion was small but significant. It was great to see old friends and meet new ones. For those who cannot attend, here are a few of the highlights as I saw them.

The loudspeaker: misunderstood, but the right speaker can make all the difference.

We just read a great article in SOS that explains a lot about guitar speakers. The information provided can be applied to all speakers and gives basic information that is often misunderstood or just unknown to most end users.

It is worth a few minutes of your time if you want to understand your speakers.  Enjoy
