Looks like a nice mod. Good job!

As you see from my previous pics, the K-63 and K-64 are identical. The only difference from what I have recently been told is the size of the magnet under the center plate with the hole in it. The good news is we can swap the diaphragm assembly to a non working K-63-KN or vise versa. I did not intend to offend you, just trying to help out Epic owners that find themselves with a bad diaphragm since these are almost non-existent.

The silver plate in the center of the driver is a cover for the magnet disk. I do not have a depth gauge so my measurement is not exact but the hole is almost twice as deep on the K-64-KN as it is on the K-63-KN. The K-63-KN has a thicker magnet that provides greater output. I will not mention names without permission but it has been confirmed.

Here is some information regarding the difference between the K-63-KN (CF-3 & CF-4) vs K-64-KN (CF-2 & KV4) as discussed in some other threads. It was stated they are the same but they are not. Although the two appear to be exactly the same except for the color and the screen on the snout of the Silver K-64-KN, they are different. The K-64-KN has less output than the K-63-KN due to the size of the driver magnet. The K-64 has a smaller magnet. The good news is both the drivers use the same diaphragm and are interchangeable. The aluminum diaphragm is very fragile and a pain to remove. More good news is the diaphragm / phase plug assembly are also interchangeable and an easy swap. Trust me, don't fiddle with changing the diaphragm, just swap the whole assembly. Here are some pics of what I did last night. I had a bad K-63-KN diaphragm that I swapped assemblies with a good K-64-KN. If you have questions, I will try to answer.

Need: KLF-20 info / light Oak color
crunchman12001 replied to crunchman12001's topic in General Klipsch Info
Hi dtel, Thank you for your reply, The above post was a follow up to my original questions regarding the Light Oak color. The two pics above your post shows the original "before pic" and my refinished "after pic". The color turned out very close using Varathane Summer Oak., followed by 2 coats of Behlen "Jet spray" Satin Lacquer. I wanted to follow up so others could match the color if they decide to refurbish their speakers. This follow up will allow it to be found when searching here. Thanks again, crunchman -
Good shape, great price. Good luck with your sale.
