Regular bondo for covering with veneer, or the bondo wood filler?

Awesome! Well, not awesome about the tweeters but awesome on the score! Make sure to post some pics.
Also, before you order new tweeters, open up the cabinets and unscrew and tighten each screw in the crossover network. It'll give a better contact point. Actually, it's possible the tweeters may work just by doing that.
When I looked at them I removed the back and disconnected the tweeters from the crossover and connected them directly to the speaker wire. Nothing. Not a peep.
Fortunately the diaphragms are only like $20 each from simply speakers and I've heard mostly positive results.

They are extremely rough. These were severely abused. I want to test the performance before deciding if I want to invest in a makeover. I have some photos in another post.

Could ya really lose on a genuine pair of Cornwall @ $600?
Both tweeters were blown. Seller gave me $150 off after he did a quick google search for k77 tweeters. I didn't argue and took it for $450.
Ordered replacement diaphragms from simply speakers and they should be here this weekend.

IMOP your suggestions will be very difficult, will cost a lot of time and money, and unfortunately will not have a satisfactory result. You are correct in attempting to ask around to find a solution that works better for you. I provided you with three strategies that will likely have an improved potential outcome for you. It would be better to make your choice dependent on your level of experience, ambition, budget, and goals. Your level of personal success will mostly be based on your ability to not over/underestimate those things.
First choice
Difficulty 2 / Cost 10/ Rewarding 6
1A) Sell speakers, run, buy new speakers, enjoy
Second choice
Difficulty 4 / Cost 2/ Rewarding 2
1B)Bondo speakers, wood filler, grain filler, black lacquer, enjoy
Third choice
Difficulty 10/ Cost 6/ Rewarding 10
1)Bondo
2)Sand 80/120
3)Wood Putty
4)Sand 80/120
5)Grain filler
6)Sand 80/120
7)Veneer adhesive
8)Veneer all sides of both speakers with wood species of choice
9)Wood conditioner
10)Water or alcohol based Dye
11)Sand 240
12)Non-Wax shellac
13)Sand 360
14)Water based Stain
15)Sand 360
16A)Speakers kept are in a room full of windows: 3 coats Epifanes Marine Varnish for maximum UV protection
16B)Speakers are not in direct sunlight: 3 coats Spray Lacquer17)After full cure: hand rub with a brown paper bag
18)Send pics so we can all enjoy
So basically level the surface and re-veneer over the whole thing?

Oiled Walnut veneer. Several edges and corners have damage with missing veneer as well as missing the underlying structure.
End goal is to remove the old finish, sand, and do something more neutral that won't yellow, like a water-based satin poly over either an oil rub to bring out the grain/dimension, or seal with shellac then poly, or maybe just poly on the raw wood.
My first thought was to clean the wound, cut out the damaged veneer, fill, sand, and replace veneer bits. This seems tedious and difficult. I'd need a thicker veneer than stock so I can sand flush.
I have also considered simply cleaning, filling sanding alone, but I'm concerned that the filler will really stand out, especially after being finished.
Any advice would be appreciated.
Greg.

Even in super rough condition like this?

A guy is selling a 1979 (T SN) pair of cornwall 1s. Oiled Walnut. No grills. He said $600 is the lowest he'd go.
What do you think?
I have a feeling they'll be gone soon.

Currently using a pair of RF5s with a Yamaha AS701 for my vinyl setup. The speakers were a great deal at $120 for the pair locally, so I nabbed them (even though I have the black variety in the TV room already).
It does seem silly have two pairs of RF5s, even though they sound really good to me, so I've been browsing local listings to see what's out there.
Well a guy is selling a mint set of KG4s in walnut for $400. They have the original boxes and even the manuals! They look absolutely pristine.
So, do you think the KG4 would be a good change for 2 channel music (vinyl and FLAC, no movies)?-

A lot of options at your price point in the used market:
Any of the Chorus, Cornwall, forte, KLF models would be a big step up so would the RF-5's or RF-7's. The KG 5.2 & 5.5 are pretty decent as well.
So you think the RF5 is a big step up from the KG4?
I already had a black pair of Klipsch RF5 for my living room and I like them a lot. When a pair of cherry RF5s were available for $120 locally I jumped on them for a hifi setup in my basement. I also picked up a Yamaha AS701 amp and Technics SL 1700 TT.

Thanks everyone. I put them back together and they sound okay to me. It's hard to tell without a reference frame.

I picked up a pair of cherry RF-5 for a great price on FB marketplace, but they were really disgusting.
I've removed all he drivers and horns and have been cleaning them up.
I disassembled the horn from the tweeter and thought that the horse hair brush on my vacuum would be gentle enough on the diaphragms. I was wrong.
I dented them and pushed them back, but now they're crinkled looking. Do I need to replace them or will they be okay?
[FIXED] Cornwall 1 bad crossover help

Hi.
I got a busted up pair of Cornwall 1s (1979) recently. The tweeters were both dead, so I just replaced the diaphragms with new ones from Simply Speakers.
When I connected it all up to test, one of the speakers sounded good for about 2 seconds and then there was a sudden drop in the treble. The tweeter and squawker are putting out sound, just very little compared to the other channel.
After lots of troubleshooting, I found that the problem follows the crossover. It's a type B.
I found it really weird that the treble dropped out so suddenly.
What could be the issue? I measured the capacitors with my DMM and they seem to be measuring properly.
