Picked up a pair of working model 20's a few weeks back for cheap ($6)... I just pulled them apart this morning & will install some nice gold binding posts... Any other economical mods that I should do? Heard people re-cap em... Debating... ???
Also, by chance does anyone have a pair of matching "KLH" badges they don't mind parting with?
Thanks for looking!

They are old enough to definitely need recapping. I've recapped 4 pairs of KLH 6, 17 and 20s. All benefited in the high frequencies from the recap.
-
Lots of info out there on "redoping" the cloth surrounds. Lots of opinions on doing that, as well.
-
How do they sound as is. Can you measure them to check performance?
-
The highs were lacking...
One issue, is that the previous owner (or a passing foe) decided to re-dope only ONE of the drivers!!! So I as a minimum, want to "match" as best as I can the woofers... Hopefully in both appearance & performance...
Thanks for looking & hope all have a wonderful & blessed Thanksgiving!!! :)

One other issues I did not mention before... ONE of the woofers was redoped w/ "black stuff."
Like the attached picture...

I have no idea of "what" was used...
The other is "original" Like this...

I really do NOT want to invest much more time (or money) in the project... I would like to have a set of model 20's that I can sell...
My questions are...
1. Do I try to "match" the other "redoped" speaker? Not sure how to do this?
2. Just buy another "original" model 20 woofer and redope this and my "original" woofer? I purchased the "Vintage AR" doping solution from epay...
Thanks for your thoughts...

I'd be willing to bet that the "black stuff" is Wet Look.

If I'm looking to flip, I dope the other to match and send them along. I might even still have some of that stuff in the basement, if it hasn't all dried out (then it would be "dry look", I guess).
-
I am not sure a pair of working model 20s is worth much more than the replacement woofer, at $50. If flipping is the goal, I agree with STaL
-
If anyone has one/a "spare" KLH model 20 woofer (4 ohm), please let me know...
As I have no way to "MATCH" the one "surround modified" woofer, I am looking for one woofer... If no one on the forum has one, I'll probably put the speakers back in the "to do" storage room! :)
I've already checked epay & there is nothing in my price range...
Happy New Year & thanks for looking!

I kept meaning to PM you. I found my Wet Look and it is still liquid if you want to try it. That's what I would do before sinking money into speakers you plan to flip anyway.
