Is that the speaker cabinet?

Did you have dreams about backpack crossovers last night?I disabled signatures. -
Lol!
They have external crossovers. They fill them with epoxy to dampen vibrations and to keep their schematics a secret.
It was a great dream hahaha- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
I guess they haven't discovered this new invention called solder yet.

Ah, I can't see that in the photo. Even when I blow it up, it just looks like mechanical connections.

Neat. Do you have to desolder to get those apart, or do they come apart?
Do you think that was to prevent backing out or truly a beneficial connectivity add?
I can't quite tell how the connectors are oriented.

If I had to guess it was to make it as difficult as possible to take them apart. Two of the binding post are loose so... Lol
Removing those nuts would be extremely tricky considering a desoldering iron wouldn't likely remove any solder between the juts and connector so you would have to keep them hot while removing? Only way I could see doing it short of breaking them off

We were always taught that the best electrical connection was both mechanical (physical, mechanical connection) as well as a welded connection (soldered connection in this case).

Indeed, solder is for maintaining a connection, not making it!
I would love to see what's inside that epoxy! I imagine it is just a Polk rtia3 crossover hot glued to a bigger board- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

I'm guessin'... no.

I'm sure there is nothing but Solen and Erse in there......

If you have to get a lot of solder off of a connection, I have had success with melting the solder with an iron and then blasting it with compressed air. Just aim the air away from anything that you don't want a million tiny beads of solder stuck to, or catch the beads in a damp rag. I'm not suggesting this method for these speakers though 😬Sources: Technics SL1200MKII | SME3009 Tonearm | Monster Alpha 1 MC cartridge | Oppo UDP203 disk player | Nikko NT-790 analog tuner | Musical Fidelity Trivista 21 DAC | Preamp: Threshold SL-10 | Amplifier: Threshold Stasis 2 | Speakers: Snell Acoustics C/V | Kimber 12-TC bi wire speakers | Analysis plus Oval 1 preamp to amp | Wireworld Eclipse 7 DAC to Preamp | Wireworld eclipse digital IC Oppo to DAC | Audioquest Quartz tuner to preamp | -
I have a solder vac but there is always a little bit left regardless of method of removal- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Alternatively, a solder sucker would work as well.

Along these lines, a friend was trying to teach me to solder about ten years ago. He was showing me the "flick" method of cleaning the tip? I don't know if this is a hack method/no-no, but never do this while wearing shorts. In fact, I don't recommend soldering at all if wearing shorts. I soldered with shorts on once...

I use a wet sponge to clean the soldering iron tip. I've found that the compressed air method for desoldering freezes the micro beads of solder pretty quickly, unlike flicking a glob of solder off the iron's tip. I've used solder wicks, desoldering irons and solder suckers. Sometimes they work great, but when you are dealing with a lot of solder, they require multiple attempts to get everything.Sources: Technics SL1200MKII | SME3009 Tonearm | Monster Alpha 1 MC cartridge | Oppo UDP203 disk player | Nikko NT-790 analog tuner | Musical Fidelity Trivista 21 DAC | Preamp: Threshold SL-10 | Amplifier: Threshold Stasis 2 | Speakers: Snell Acoustics C/V | Kimber 12-TC bi wire speakers | Analysis plus Oval 1 preamp to amp | Wireworld Eclipse 7 DAC to Preamp | Wireworld eclipse digital IC Oppo to DAC | Audioquest Quartz tuner to preamp | -
I have a couple of different solder suckers, the bulb one and the plunger type. For some reason, I haven't been able to get solder wick to work. I've seen it done in videos and can't get over how clean the solder pads look afterward. I can barely get any solder off with them, but have seen in those vids how they do actually flow the solder up.
In all fairness, that flick method was due to the fact that a lot of his solder work is as a mobile installer in new construction and he's using a benzo iron. @F1nut recommended one of the Weller soldering stations and Cardas quad. I've been using that combo and have to admit, it makes things a lot easier. I couldn't even get the tip tinned with the basic Weller pencil irons. One time I thought I was getting the hang of it and though I saw solder flowing, feeling kind of excited, but it turns out that it was bits of the tip melting and dripping off. How the hell does that happen you ask? It was because I got frustrated with the dirty tip that wasn't taking a tinning, so I thought it needed to be properly cleaned, and sanded it down with emory cloth. Took the coating right off, lol
But yeah, having the right tools and materials makes a big difference.
Still have soldering anxiety, which pretty much makes me avoid those projects, but then once I get started it's fine. One of these days I'm going to rebuild crossovers.I disabled signatures. -
What does potted mean?
I couldn't tell from looking at the photos on mobile that that enclosure was filled! It wasn't until I saw it on the computer that I noticed the bubbles and irregular surface and then finally understood what you mean.They have external crossovers. They fill them with epoxy to dampen vibrations and to keep their schematics a secret.
I would have thought those crossover components would heat up enclosed in epoxy like that, but I know nothing. Natzing.I disabled signatures. -
Yeah all of the resistors are outside. Inductors and stuff can heat up but usually not much.
I have a solder vacuum to dealer and it really is amazing. Literally sucks it all up in an instant- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

Actually, that potting compound (Stycast) has a specific gravity close to that of water, so it actually helps by transferring the heat into it's thermal mass.Sources: Technics SL1200MKII | SME3009 Tonearm | Monster Alpha 1 MC cartridge | Oppo UDP203 disk player | Nikko NT-790 analog tuner | Musical Fidelity Trivista 21 DAC | Preamp: Threshold SL-10 | Amplifier: Threshold Stasis 2 | Speakers: Snell Acoustics C/V | Kimber 12-TC bi wire speakers | Analysis plus Oval 1 preamp to amp | Wireworld Eclipse 7 DAC to Preamp | Wireworld eclipse digital IC Oppo to DAC | Audioquest Quartz tuner to preamp | -
FWIW, I still like, prefer, and use "Bonus Wick" (desoldering braid) for general desoldering and cleanup of, e.g., a through-hole, when needed.
I will also -- ahem -- cheat when doing repairs of point to point wiring by snipping out the component and making pigtails using the old leads. Don't tell anybody!
This is not, of course, a good idea if you're working on a tuned circuit* nor for something like a grid stopper resistor that needs to be right up close to the socket connection -- but it makes for quick 'n' easy repairs of stuff like interstage capacitors. Did I ever mention that I am preternaturally lazy?
N.B. I wasn't exactly proud of the work I did on that gorgeous 8B -- but I used the components provided by its owner and boy howdy did it sound magnificent once refreshed. Just a superb design and a marvelous amplifier, by the standards of the early 1960s or today's.
Otherwise, there's value in a reworking station if one's serious about doing... rework.
The other thing to consider is an inductively "heated" soldering tool: the New England gurus buy Metcal stations, often used ones (they're quite 'spensive) -- and swear by them.
Oh - PS: There is still, IMO value added with a good old soldering gun for heavy-duty desoldering (soldered in can caps, braiding on coaxial cable, that sort of thing). Tim "The Toolman" Taylor wasn't completely off-base about the value of more power (insert gutteral grunt here)! Hot and fast can be easier on the circuit components than worrying something out using a too-small/tool cold pencil iron.
All just my opinions, of course.

So I picked up the ANK monoblocks to run with these guys and they sound really, really good. Great imaging, micro details. Great solid center image, good extension beyond the mains on the sides and depth. A big improvement over my cheap integrated ($50) obviously.. Running a cheap little $20 bluetooth dongle which is more than enough for now to interface with the computer.
But so far very pleased with the sound nearfield. The Wilsons are full range on a desk, no doubt.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
