Probably the speaker to compare the KP-250 to is the HIP instead of the H2. The HIP also just attenuates the midrange by 3 db. In every case, I would think Klipsch attenuated the mid to match the output of the woofer.

I think all of the electronics are in the right speaker. That is the one that has the AC power cord and has all the controls on it. The right speaker connects to the left with a supplied cable. The Sixes have been very interesting to my customers with most asking "What the heck are those?". And after a quick listen, these customers are quite amazed by the amount of bass they hear from these very small speakers.

I think if you put in an L-pad and attenuate about 3db, it will sound better than a K-79 with stock diaphragm. But probably not significantly better than just replacing the diaphragm with my titanium diaphragm.

Those are probably all mylar. I don't think I have so far ever encountered a poly cap in a Klipsch speaker.

I agree with Bob here. I have found that the poly film caps do not deteriorate like the old oil filled ones. That being said, it's all about the Equivalent Series Resistance, which when high, it tend to go towards less PURE capacitance and more resistive.
I will disagree with you about film caps. They age just as quickly as any other caps. Notice the ESR reading on these. They are all film caps from Klipsch crossovers.

Capacitors deteriorate from age whether used or not. I got to find that out back when I was using the GE oil filled caps. They had been in production for many years and once my supplier sent me some with some very old looking boxes. I tested them and found them all to be high in ESR. These had never been out of the boxes, but were bad just from age.

Has anyone used DE 120's with a pair of Chorus speakers? I am getting a pair and wondering if this is a worth while upgrade people might be interested in.
You would have to attenuate a DE120 a lot to use in a Chorus. It will be much too loud.

Well, obviously have not tested every possible combination, but this adapter is very short and was made by Tonsil to be used with their driver to allow use of some different horns other than the one they sold for use with their driver. Anyway, the adapters turn the Tonsil (as far as mounting goes) into almost the exact thing as the current APT-50.

By the way, there is an adapter that converts the original Tonsil driver to the standard 1 3/8 18 thread.

Just look at this PDF from back when Eminence used the Tonsil driver. And then the Eminence data sheet for the current driver here.
-
The one with the 1 3/8 18 thread is the clone of the original Tonsil driver that had a different thread. The original Tonsil driver that I use looks like this. Sorry this is an old dirty one that was in my junk drawer, but you can see the way the threads work.

That is good to hear but why do they say discontinued on their web site? Are you the one who cleaned out Parts Express ;D
I don't know why it says that. Their Sales and Operations Manager says they will stay in production as long as there are orders.
-
The DE-120 is still in production and no plans to discontinue it according to B & C. I received 50 of them today.

The K-52H was built by Heppner. Klipsch bought the company or perhaps just their driver tooling and sent the tooling to China to be used for driver production. The also did a large mod to the diaphragm that combined diaphragm and phase plug into one single plastic unit. With Heppner, the phase plug (witches hat) is a separate metal unit that just fits up against the diaphragm. Also, the driver was changed from a thread on to a bolt on and the plastic horns for front mount were made to match the modified driver.
-
The last 2 or 3 years of production, Klipsch started using the new midrange horn and driver in the Cornwall 1. Goes along with the B-3 crossover.

Ok, I need some help with the 3636 autoformers. What are input and output in comparison to the original T2A to keep the mids at the same -3db level and the tweeter output the same as original?
@Deang are you still awake? Or anyone out there? Ha
For that attenuation, use all the exact pin numbers as the T2A used.

I can access the main page and most of the links are working. However the links to the CT120 and A55 G are still down.
Something is messing with some internal links. When you tried to go to the A-55G page, you got a link that looks like this.
https://www.critesspeakers.com/critesspeakers/k-55-replacement-the-new-a.html
Notice the extra /critesspeakers in the link. I do not know where that is coming from. You can edit that link to remove the extra /critesspeakers and the link works.
Perhaps one of you web experts could tell me what is doing that.

Just went to a secure certificate for my website. Trying to work through all the problems that caused. Seems that with some browsers works fine but with some, not so fine. You should be able to go to https://critesspeakers.com without problems and the links at the top of the page should all work. Links on Google except for the main site link seem to be corrupted some way. @critesspeakers.com should also work and seems to work on some browsers.

Dean,
Do you remember the rest of that statement? The part that comes after "we are a speaker company, not a speaker parts company"

I would say factory paint. That is what the HBB should indicate. Heresy Birch Black. If it had no finish applied it would be HBR. Heresy Birch Raw.

I have never installed any fabric, so I don't know. Far as I know it installs just like any other fabric.

Here is a relatively new fabric called "Cane". It is really an imitation meant to look like cane.

What you really have to compare is sensitivity. The H2 is about 96 db at 1 watt. The ported versions are around 102 db at one watt. So, the ported versions, you would have to attenuate the midrange about 6db less to match the output of the woofer compared to the Heresy II. Anyway, the attenuation on the H2 is 10db. On the ported versions the attenuation is 3db, a difference of 7db. They have is set to 3db on the ported versions, so pretty close to the calculated 6db.
