Final update for a while. Found a k-55m on eBay for $165 and the guy took my offer of $125. Installed it today (although I need to solder some new contacts in it at some point), and both speakers are sounding amazing. Cosmetic updates are next, but I’m traveling for a bit so it’ll have to wait. Thanks for all the help getting these beasts up and running!

Ok tweeter diaphragms replaced with a Crites kit! Sounding good! Now I need to replace one K-55m, the question is do I get a pair of Crites kits, or do I hunt down a single working K-55m? Is it bad practice to get them individually like that? Like a chance of some imbalance?

Does anyone have a recommendation for paint for the squawker horns on these? Gotta replace the squawkers so I may as well remove the horns and paint them (they are peeling and need it pretty badly).

Yeah I did enough digging to figure out that’s an option. Ordering replacement kits from Crites. Not positive if these fit the square back tweeters though (https://critesspeakers.com/products/k77-diaphragm-kit) I think so? We’ll see, I emailed them to find out.

Ok, tweeters are all over the map too. So all told I guess one bad k-55 and two bad k-77. Reputable place to buy replacements? It seems like k-77m is the way to go for the tweeters?

Ok, swapped non working squawker to the working squawker side and it isn’t firing. Tested with a multimeter and the numbers are all over the chart, nothing steady. So I’m guessing this K-55-M is shot? Anything else I can do with it with little technical knowledge? Or should this go off to repair or should I just buy a replacement? tweeters are next.

Quick question, does this include the screws that mount the network to the body of the speaker? Those Philips head screws in the photos? those seem to be the only ones that have corrosion. all the screws holding the wires down (flat head screws) are super clean, like they just came out of the factory - I unscrewed and tightened all of those, but no change. Next up, multi-meter testing.

Is it worth cleaning those connections while I'm in there? Deoxit or something similar?

Just got a pair of 85(?) La Scala Pros that have been sitting in a shed forever. Woofer works fine on one, but no sound from mid or tweeter. Woofer and mid fine on the other but no tweeter. The backs are sealed on these so I removed the screws and opened them up to take a peek at the crossovers - everything is amazingly clean, although the capacitors seem rusty. What’s the best process for me to follow to identify what’s wrong with these. Not afraid to learn new tools and such, but am a novice to these things. One photo of crossover attached here.

Hey all, I'm just starting to put together a hobby room/man cave space, and an opportunity to buy a pair of Heresy II floor speakers from 1985. Is there a way for me to test them without dragging out a receiver/amp to the sellers home? Also, is there anything that is a common issue with these that I should be on the lookout for?
