Cornwall II finish

Recommended Posts

I have 1988 Cornwall IIs with the black finish. A prior owner applied a bad application of polyurethane and I need to fix it. I don’t know what is under the black veneer or is it a furniture grade plywood? Any tips on how to fix this issue is appreciated. 12F28090-8E82-4192-842B-DB3891A52E6F.thumb.jpeg.329d967d16d770c2270d46defe80f0b9.jpegF94D741B-972A-457B-86EA-03C3EC37CE6F.thumb.jpeg.9b7e36d6af3db632409936b08b19d28d.jpeg

Pull all the drivers and start sanding it all off until you get to the wood

I’ve don’t the same thing with a old Yamaha pro speaker and it came out wonderful

It takes a lot of time. So you may want to use a electronic orbital sander, like a 6” from harbor freight, unless you have air tools

You could also use Aircraft paint remover or something on that lines, you just apply it let it bubble up and scrape it off and keep doing it till you get as much off as you can. Then you finish it off with sanding it. It have a long and hard job ahead. Good luck

It came be done. Just takes time and elbow grease

You could also pay a furniture refinisher shop to do it for you. Would be faster but will cost you. They would use the paint remover and a sandblaster to remove all of the junk on the cabs

What’s your location?

I don’t have serial numbers since the original panels were updated with Chorus units back in 1990. Sorry I couldn’t rotate the photo.DF2B540E-1A64-448C-B2A6-1636AE65AF9B.thumb.jpeg.d43e4e597c89fa4f14993af759ce4bc4.jpegA22A7389-5354-4034-8B99-009F983162FB.jpeg.f91810ec5a038a14eeedb3df23c629bc.jpeg

They should be stamped on the top edges of the rear side of the speakers

I heard of that, they are not there. I took the speakers to a Klipsch Dealer in Williamsport, Pa and was told the reason there are no serial numbers is because they would have been stamped on the original back plate. Since they were replaced with Chorus crossovers which are just components not a complete speaker system there would not be serial numbers stamped. I was also told that the Chorus crossovers should be a seen as a slight upgrade. Would that be true.

 

To Carlthess40, I am located in York, Pa.

 

thanks for all the tips and advice.

I’m thinking it is a furniture grade plywood under the polyurethane and paint.

i removed the midrange horn and found a tag showing the cabinet inspection in Jan 1988. I could also see the cut around the horn and don’t see any signs of a veneer.  

 

 

see any veneer.6A717045-CC5A-49EC-9DDE-8C26EA7294D4.thumb.jpeg.90acf60e0a05d40daca6338f4902910d.jpeg59827807-551E-4FF9-B23F-FC250927FFD1.jpeg.f65241eba267db672a68304ee9d077bd.jpeg

I talked with customer support at Klipsch and sent pictures, Zach is going to take them to the older guys in the shop to get their opinion. Above and beyond customer service.  I think you are right about the finish. I’ll post what I hear from Klipsch. Thanks again!

I know you said to do top and sides only, why not the face if all components are removed? Any concern about doing the front edges of side panels that face the front of the speaker? Sorry if I’m asking bad questions.

I removed the polyurethane and black paint and found a veneer.  Not sure what kind it is but I think with proper sanding and care I can bring back close to original look. I’m ok with a little wear after 31 years.  I still have to remove the old stuff from the rest of this and the second speaker.

 

I'm open to any thoughts or tips on how keep this vintage look if I don’t find any major issue as I move forward.

Yes it is a good idea to keep the vintage look of the speakers. If the black cannot be removed completely, you can make a very modern industrial vintage look 👍

 

If there is no surface repair to be done or if you voluntarily choose to leave the marks of time, gently sand with super fine grade 0000 steel wool and use restorative beeswax with a tint your selection. This often gives very beautiful results with just the right amount of patina.

 

A few tips

I don't think this has come up yet, but those crossovers are for the Chorus. You'll need to remove, and swap with the proper Cornwall II x-overs. The schematic is posted in the Technical/Modifications, but it's unusable (low res and too small to read). Someone might have it handy, though. If you'd rather not go the DIY route, you can purchase a pair direct from Critesspeakers,com.
