Everything I wrote are things others have said, taken straight from the Klipsch Facebook groups and someone’s webpage. So you agree it sounds stupid and immature? I guess I made my point.

Well, everyone knows Roy and Klipsch could care less about support for vintage Heritage. They will lie, mislead and do whatever it takes to get you folks to drag them to the curb and buy new speakers. Klipsch also has an incompetent engineering department that’s afraid of being shown up by third party vendors, where the super smart people work - that’s why they don’t want us talking about them here! All of them networks look just like Klipsch so they must still be Klipsch! Yes yes I know the parts are all different and it sounds different but prove to me it’s different! It’s a factory spec upgrade! 🤪 lmao. Some of you have lost your damn minds.

People ask for proof, and when you give it to them, they don’t listen. It doesn’t matter how many times or ways you explain it to them. Measurements were provided here, for both capacitors and autotransformers. I just posted ESR measurements on the Vintage Klipsch Fans Facebook page a few days ago. No one really cares, either due to confirmation bias, or simply an inability to grasp the implications. I was going to post Boxler’s amazing results on the autoformer with some of my own measurements. I have decided not to waste my time. It’s an exercise in futility. Considering what has transpired here over the last year it is astonishing that there are still people who think that nothing has been proven or discussed at length.

Those aren’t Type A’s. Don’t run those with stock tweeters. That network runs a lower crossover point that will stress a K-77. CT-125 is an Eminence APT-50

Bob never called his networks “upgrades”. He never wavered on this. I am very much on the record of not liking the sound of any of the Heritage networks built with the Sonicap. Bob was very well aware of this and mostly just found it amusing.

Sometimes there is a thin layer of oil on the surface of the can. You can feel it on your hands after handling. They should be replaced at that point. No reason to wait until it’s leaking on the board. I’ve measured a lot of these over the last year and ESR is typically twice that of a new Mylar - around .80 To the OP. A low ESR polypropylene will tip the balance forward. The speaker will be too bright, almost painfully so at live listening levels.

In first post he said B&C tweeters and crossovers. I think be meant to type B&K Sound (Crites).

Nothing was purchased from me. So I guess another faux “upgrade” from you know who.

Yeah, don’t run the Type AA with the two port phase plug drivers. Thank you Mike!

You could measure a K-55-M with an AA to get a complete picture. Would be nice to settle this one. Seems maybe you can do two port phase plug with the AA, but should not do AK/AL series networks with the single port phase plug driver.

Here it is with the AK network. I know from John Allen that it was the driver used to develop the AK network in anticipation of the EV replacement (K-55-M). I confirmed this with Jim Hunter. EDIT: @geoff. Any explanation without confirmation is just conjecture, and since you are not the original owner of those LSI's, we can't really say for sure what networks those speakers shipped with. What are the serial numbers of your speakers? Another explanation is simply what Randy said. I don’t make the recipes. I’m just the cook. ¯\_(ツ)_/¯

Basically. The problem here is that the AK series of networks physically separates the high pass and low pass sections. Everything related to the bass is in the bass bin.

Are you the original owner of your La Scalas? Do you know their entire history? A lot of these systems were abused and overdriven. Mismatched drivers and networks are common with them. It doesn’t help that people are being told it doesn’t matter what networks are run with what drivers. I feel like you might be conflating issues on the last part of your post. I’m pretty tired, so I may not be getting what you are saying.

It's a virtual clone of the K-55-M. John Allen told me to build AL-3's and AK-3's for that driver.

I don't know how to answer that. It was a transition period. Maybe the AL/AK series of filters weren't ready yet so they used what they had available to them. It's a question for @JRH Jim Hunter.

Don’t run the AA with the EV drivers or the Atlas two piece phase plug K-55-V. AL-3 was the Klipsch upgrade from the AL. So why run the AL?

Heresy III kit.

You are doing the best you can with what you have available to you and you aren’t aggressively promoting non-Klipsch products or services. I think you’re fine.

Randy, Please stop editing your posts after someone responds to your original statements. Not cool. Dean

You should stop. You often seem out of touch. The parts are high quality, they just happen to be the wrong parts for a vintage Klipsch rebuild. My personal take is that their networks just don’t sound that great. Actually, most business goes to Crites. Accessible customer support Online shopping Overnight shipping Payment plans Free returns Nothing Jim or me offer can satisfy the appetite for instant gratification. I certainly have no desire to build junk so I can compete with what amounts to a small factory. I’m out in the wilds quite a bit, and there is no end to the complaints of poor customer support and lack of real support for the vintage stuff - and almost everyone is absolutely tired of the K-77 tweeter. I am incapable of building an argument to continue its use. Sorry,

They can, with the right parts and instructions. Two of the parts he is asking about are not available. He started a thread in technical and then disappeared. ¯\_(ツ)_/¯

@JCBOHL Where did you go? Can’t help without more information.

Welcome back. You should probably read the sticky’s at the top of this section. I am possibly interested in high quality replacement PCBs, and I have an idea or two. Things have really died down. 1) The economy 2) Cost of parts and labor (as you found) 3) The fact that the network updating business has been dominated by four of us over the last 20 years. I sometimes wonder how much is actually left to do - coupled with the fact that younger people don’t have much interest in this. Those that do are pursuing HT or vintage on the cheap.

Except when PWK did it, lol.

What is wrong with your Forte II Networks?
