Holy Mackeroly! I mean DANG...........Those pictures tell the story of an EXTREMELY complicated build process - and very skillful work too. They look amazing. I'd love to hear "Frankenstein" (Edgar Winter) thought those Babies!!!!!

Understood - thank you.

as OO1 suggested, I looked closely at the diaphragm that I stupidly damaged by disassembling the K-77 the wrong way and I see that there is copper wire still connected to both POS and NEG sides of the unit (about 1/4" of super fine wire). Also, on my K-77, there's no plastic parts - it's all metal. The diaphragm sits down into a metal dish and the diaphragm seems to have a cardboard gasket attached to the back of it (maybe fused to it over time?). Not sure. It can't hurt for me to try and repair this diaphragm using the method suggested by tigerwoodKhorns - sounds......possible.....but, I doubt my chances are very good at success due to my less than expert soldering "skills". I'll let you guys know how it turns out. Also, since there is wire still connected to the diaphragm, I was able to get my meter on it and confirm that it has continuity. That's good news.

100% agree - and it's only the Cheapskate within me that would lead me to even considering "economy" solutions for my Heresy's.

Understood - thanks very much for the sage advice on this - I definitely do NOT want to have my tweeters sounding anything other than exactly as they sounded when they left the assembly line in Hope back in 1977.

You Klipschians are SO AWESOME, I swear to God. Thanks for all the responses and info. Considering purchasing 2 new aftermarket diaphragms from Simply Speakers for about $22 each to replace both. Pretty sure they will do the trick, but can anyone comment as to whether or not the horns will sound the same? Worse? Better? Any other sources for these diaphragms? @ Mark 1101: I'm also going to check out your drivers for sale - thanks for bringing that to my attention.

Might as well ask this question as well: The reason I was taking this apart, was to see how the lens connected and how it separates from the magnet and diaphragm. I've been looking at the aftermarket lenses that replace the existing lens and mount flush to the front of the motorboard. How does the lens come off of the K-77?

Bored and curious this morning, I removed the 4 screws from one of my K-77 Heresy Tweeters and wanted to see how it came apart - but I think in doing so, I've broken the electrical connections probably - wanting to see if anyone who knows about these drivers can confirm? Right now, I don't want to believe it, but I think I know the answer. If I have in fact broken it, of course the next question is: can it be repaired? Or will I need to purchase a new diaphragm? The wires coming off the diaphragm are smaller than sewing thread....can't see how they can be reconnected (by me). Thanks.

I listed as "Best Reasonable Offer".

It is in fact not steel - thanks for that correction Marvel.

Thanks......thanks a LOT.......: > ) for posting this............looks like a pretty amazing shop for an old guy like me to spend.......... 1. Hours in - drooling, dreaming, shopping/haggling. 2. A significant % of his hard earned Retirement Money. 3. Enough time in only to realize he's forgotten exactly where he is or how he got there...... 4. See #2 and resulting consequence = "PO'd wife". I'm close enough to drive there and will definitely be checking it out.

Driver Sold on Reverb. Horn still available.

Yep, I think that's correct......the 7 is not clear at all. Anyway, very cool bit of Early Americana there.

Can anyone spot the specs error in the images above?

Found a VERY old advertisement for them - from 1923.
