My bad, apologies.
Actually that is Al's fault. You just repeated what he says on his website. He can't seem to get that figured out and make the correction on his website.

Mr. Bill nailed it....I have the CT125 tweeters in my Cornwalls, and they are more laid back sounding. I had a pair of (Eminence) Adire HF12 coaxials that used APT50 drivers for tweeters, and wasn't too thrilled with sound of those coaxials. The APT50 is okay sounding, but a cheap driver nonetheless...
Mike,
The CT125 has NEVER used the driver you show in this post. That driver is pure junk. The CT125 uses a driver made by Tonsil in Poland. The one you show is a clone of the original Tonsil driver Eminence had made in Asia.

Well, I think this is fixed now. Seems it was a hack of the server on Godaddy. Specifically looks like a hack to redirect traffic to a different website, but the hackers were fairly inept and redirected to a non-existent website. Whoever those worthless turkeys are, they owe me about 4 hours of my Saturday back that it took me to get this fixed.
Anyway, a Google search for Crites Speakers now gives working links.

No kidding. Very weird and it's happening with both of your websites. It could actually be Google as I've seen it happen with some websites the school I used to work for accessed and it would have these issues on occasion. Something had to be done on Google's side if I remember correctly. It may fix itself...it may not.
But, it is google, bing and yahoo. What is common there?

Does the same thing on Bing search, too.
@BEC Who is hosting your domain/web site? Are you doing it? I'd check with whoever is hosting it.
Godaddy is hosting. Talked to them a lot this morning. They cannot find anything wrong on their side. What makes this really strange is that only the major search engines like google, bing or Yahoo show this problem. Try any minor search engine like duckduckgo or dogpile or AOL and no problem with any of them.
I am very confused.

Also works on a search on www.dogpile.com
This is strange

Yes, parallel.

Some of the tweeter diaphragm had that and some did not. Probably only phenolic made by one of the companies that made them for Klipsch.

Bob guessing that would be the same for chorus 1 and 11s? Thanks!
Yes, all use the same diaphragm.

I am surprised to hear that Bob suggests to not use the tweeter damping. I add tweeter damping to all my tweeters along with a layer of dynamat on the pole this all helps to minimize reflections and smear. I would suggest that folks do an evaluation with and with out. No way they will sound better without.
This is wrong at least for the diaphragm the OP is talking about. That fiber or anything else touching that extremely delicate titanium dome will damage it. Even a fluffy cotton ball will damage it.

I have a pair of The Sixes. I am truly amazed at how good those little speakers sound.

I think that stuff is usually called MDO. Medium Density Overlay. It is plywood with a resin overlay on both sides. I was told a main use for it was for highway signs.

Looks like Zinc Chromate?
Common on EV magnet structures (woofers too).
According to report from a customer of mine it is quite irritating to the eyes. He opened up the back of his old Heresy, saw the yellow powder, took a deep breath, got as close as he could to the back of the tweeter then blew as hard as he could. Said he got a pretty even coating of the yellow powder on his face including the eyes. Spent quite awhile with eyes under a faucet trying to wash that out.
-
On the yellow powder subject, I see that on most of the K-77s that age or older. I guess it is some sort of oxidation of whatever coating is on the tweeter.

I opened them up and they have type "C" crossovers that appear to have been modified to type "E" with a Bob Crites kit.
Just for clarity, the crossover may have been modified with parts from me, but what I see in that picture, is NOT my work.

I have not run into a bad diaphragm on a K-55M that still worked. On some very old K-55Vs, I have seen that they tend to loose output in the area below 1000hz. In that case, a new diaphragm fixes them. As they age, we may see more problems with the K-55M. Also as they age, the plastic ring you have to reuse on the K-55V diaphragm to use it as a replacement on the K-55M gets more and more brittle. When one breaks, not sure what the next move is.

Yes, there is a better driver, the A-55G. But, look into the plastic back plate on the K-55M. It could be loose as Mookie said in his post above. Usually that shows up as a buzz, but could possibly just cause distortion.
-
There are no diaphragms available for the K-55M. I have managed to modify K-55V diaphragm to use in the K-55M, but that is a tricky procedure and probably not a good thing to do as long as yours are working.

Catching up and these replies are not encouraging. If I am not going to get factory specs with the re-cone kit I might as well buy new Eminence woofers. By the time I pay the re-cone dude in Nashville for incorrect parts I am over two thirds of the way to new. Actually in the case of 15" K33 woofer replacements I am money ahead by buying direct from Eminence. Surely there is a better answer.
On the K-43, have you asked Klipsch if they have the recone kits. They used to have them. In fact I have a couple of the K-43 recone kits I bought from Klipsch a few years ago.

Eminence will only sell custom cone kits to the original customer (Klipsch), in large quantity.
And they will only make those kits as an addition to an order for the woofers.

Here is a little tip about mounting the steel core inductor. If you use a steel screw (one that can be picked up with a magnet) through the core to mount these, you will actually add a bit of core mass and that increases the amount of inductance. I ran into this one time using that style inductor and the increase was enough to effect how the circuit worked. This can be solved by using a brass screw or a stainless steel screw.

What I get from them is the 4 X 8 sheets of Russian Birch. It is 18mm in thickness which is about .71 inch thickness.

So is it an overkill to build cabinets out of Baltic Birch these days? Is the $50 per sheet of 4 x 8 Oak or Birch ply from the bog box lumber stores going to suffice for most jobs? I've seem some on here that appeared to have used it with decent results.
In case you do want Baltic Birch (now called Russian Birch) you can get it pretty close to where you are. Acadian Wood Products in Little Rock stocks it. They deliver it here to Russellville for me, but I am always buying a large number of sheets at a time. The reason that they stock it, is because of Klipsch so would be the same stuff they use.

Well, this is a bit complicated. Originally the APT-50 Eminence sold was the Tonsil driver. So, yes I started out using the APT-50. When Eminence had a clone made of the Tonsil driver, they sent me a sample and it was junk, just plain not usable. So, I contacted Tonsil in Poland and had them make that original driver for me, so I have always used the Tonsil driver. The APT-50 that Eminence sells now is not interchangeable at all with the Tonsil driver. Even the mounting threads are different.
