Hi all, I am restoring a Bush DAC90A and the speaker is beyond repair. It is 6.5" round, 3ohm and I can't find a general purpose speaker to replace it. WES components, RS Components, Jaycar, eBay and Altronics don't have a general purpose in that size.

I can get speakers with a tweeter in the centre which I assume are automotive, are they ok to use. The original speaker is permanent magnet.

Has anyone used an automotive speaker in a vintage radio?

Thanks in advance

Nothing wrong with using a wide range speaker, probably better than the original.
Over specified for AM radio audio frequency range, but good.

Thanks Johnny, I'll give one a go. Cheers!

To those restoring Bush radios with Celestion Speakers.

As it turns out I was able to repair the old speaker. It was extremely rusty and the spider had come adrift from the top plate, a common problem with these speakers I believe. When pressed down the voice coil was rubbing on the core. (Due to the rust I found out)

I was able to cut around the top of the cone next to where it is glued to the basket leaving a small lip, I unsoldered the voice coil flyleads and removed the cone and voice coil as one. I sandblasted the basket and repainted it, I also cleaned and treated the rust from between the magnet and core. That area has to be spotless so it took quite a while.

I cut a ring from some sturdy cardboard and glued the cone to it to form a new lip. I then used a piece of paper to position and centre the voice coil over the core and re-glued the spider. Once dried I glued down the new lip to the edge of the basket and soldered the flyleads back to the terminals. After removing the paper spacer from between the core and voice coil I glued a piece of felt over the opening as a dust cap.

The speaker works as good as new and I can retain the original speaker in the radio.

Well done!

I've restored a few speakers of the type that you can unbolt but I've balked at glued-in spiders and lots of rust.
