To be honest, if you could read the schematic it is quite easy. Maybe someone already has a picture of what to change that they could put up here..

Sure you could use an air core coil for the 2.75mH. But because it would need so much more wire the max of .4 ohm DCR will force you to go way up in wire size (read more $$). Also, air core coils are a lot more sensitive to proximity of other coils.
As for .15 or 2.7mH, I am sure many people have done it that way. In my case I guess I'm just too anal when it comes to spec's. So I would buy the next higher value IE: .18 or 2.8mH - measure them and then unwrap the coil(s) to reach the .16mH or 2.75mH final remeasured value.

Some typical DCR values would be
air core .16 mH
-
18ga ~.15 ohm
-
16ga ~.1 ohm
iron core 2.75mH
-
18ga ~.34 ohm
-
16ga ~.2
Naturally the resistance goes down as the wire size goes up.
On my first budget forte II crossovers I used 16ga for both coils and was happy with the results. I went with 14ga on the 2.75mH coil with the next pair built. But unless you push gobs of power through your forte IIs, or you are pk with the extra cost, the 16ga will be fine.

Welcome to the board,
The .16mH is an air core inductor for the HF and is such a small value (read not a lot of wire) that the DCR would be minimal .
The 2.75mH inductor is an iron core and the OEM schematic specifies that the DCR to be less than .4 ohms.

It does not make sense. If you have stock of old crossovers it will take 2x faster to get rid of them in pairs then to mix them with new.
Maybe they already started to factor Forte II in parallel and someone put wrong gone. Any way capacitance values can help to resolve that.
As posted above, early on Klipsch was still using the PCB used in the original forte I with different component values for the forte II. -
I bought a used set of early forte IIs that came with the forte I PC boards but populated with the correct forte II values. My xovers look like your top pic.
.A friend of mine has a later set of forte IIs and the xovers look like your bottom pic.

I personally would not hesitate to continue using Crites.

Over the years I have re-capped a good number of Klipsch speakers, forte 1/II, Heresy I/II, Tangent, klf-xx, kg-xx, Quartet. Most were done with Dayton/Solen class caps and in every case there was an improvement in the sound afterwards. How much better varied, but still the improvement was quite obvious and the best way to describe this would be removing a blanket that was over the speaker beforehand.
As for what type of cap to use - be it polyester, polypropylene and others; it will always be a never ending debate. Polyester is what Klipsch uses and lets face it - it was a cost factor. They looked at what sounded best for a given price point. Period. Of course, that does not mean they sound bad because of them and if you like that sound then by all means replace them with the same type.
But nothing is perfect and there is always room for improvement - Klipsch is no different.
-
If you are currently happy with them then leave them alone.
.
But the issue is that capacitors have finite lifespans unlike most other electronic components. For most people they agree sometime after ~20-25 years that we replace the caps would be a good idea.

Congratulations!
Well, since you own them, what is the answer to you question? IMO, if the question is “easily removable,” the answer is no. If the question is removable, the answer is yes, but time consuming and possibly not worth the effort. What have you decided?
Thanks
The best I can tell it looks like you would be doing some damage if they were removed. So we will leave them as is until it is determined that the grills could be removed safely.

E6000 is a great glue used in many places including jewelry making.

Maybe used Heresy 1s? Depending on your location you should be able to pickup a few decent pairs for around the $500/pr range with a bit of patience.
IMO from a performance stand point the Heresy will walk all over the other two that you listed. But looking at your first choices I wonder if size might be a factor.

Have you looked into the Heresy's? They are common in commercial settings and would fit into your retro theme nicely. There are some pros here, maybe they will chime in.

klipsch Approved , means klipsch Genuine Parts sold by klipsch to JEM -
You may be right if JEM gets their caps directly from Klipsch. But for some reason I was under the impression their source wasn't from Klipsch but rathjer it was that they meet Klipsch specs. -

-JEM is a klipsch Dealer and a Certified repair Center and Seller of klipsch crossover parts - and just like GM dealers buy Genuine parts from GM -JEM buy Genuine parts from Klipsch -
In this post & I believe Chief Bonehead also said the same elsewhere.
