I’ve been hearing a lot of people saying that the Titanium upgrade really does improve the Highs that can otherwise be fatiguing at times , is this true? Thoughts , opinions? Cost w/shipping included is $69.90 and I’m having them installed by a professional at $20 each. I’m not out a lot of money!! $109.90 installed!!View attachment 1342791 OK , so I “ Finally “ did it and ordered a pair of Bob Crites K-74-K Titanium Diaphragms for my Klipsch KG4’S!! What will be the biggest difference in sound vs the stock Phenolic compression driver?
Thanks for the response, I’ve been putting this off for a few years now!! I didn’t go with replacing the crossover because the technician at Midwest Speaker Repair said the 1,800hz frequency response is exactly the same with the Titanium vs the original phenolic Diaphragms in My KG4’sHey it takes 10 mins at most with a screwdriver per speaker, you can do it yourself...just do NOT touch the diaphragm itself and be careful with that screwdriver!
As for what it sounds like...on my 4.2's there were two main differences. Response was damped down a bit in the midrange where it sounded harsh (loud really) - in the electric guitar part of the spectrum. And, it opened up the top end and I was hearing delicate highs I had not heard out of the stock diaphragms. So I'd say all in all it created a much more balanced response curve.
So the sound is going to definitely be better? The current Diaphragms give the highs at high volume a “ Harsh “ uncomfortable sound at time. I’m excited for this change!!Thanks for the response, I’ve been putting this off for a few years now!!

Do I have to special order the caps or will my technician guy more than likely have crossover caps?I think you will like what it does to the top end. Best money you can spend on these speakers.
I didn't replace my crossovers either, but I did recap them - just two caps - since they had a lot of miles on them. But they are film caps so they are not likely to be THAT bad. Put in the diaphragms and if you want more tweaking, put some nice caps in.

Thank you Joe for your input , I really appreciate it. I’m not going to replace the crossover because the technician at Midwest Speaker Repair said and backed up what you said about there being no difference in sound quality due to the frequency response being exactly the same and using a good quality amplifier, which I have , the Denon AVR 3300 , will not be necessary to upgrade the crossover! I’m excited to hear the difference!! Thanks again for your input!!Bob Crites sells complete crossovers and capacitor kits which use good quality Sonicaps. I priced out the caps individually and Bob's price was less than I was able to find elsewhere. Swapping the caps is more difficult than the diaphragms but certainly DIY if you're reasonably handy with soldering.
Thanks,
Joe
The original “ Phenolic “ Diaphragms in the KG4’S K-74-K have a frequency of 1,800hz and the Titanium replacement K-74-K frequency is also 1,800hz so I’m assuming that the need to change the crossover is therefore unnecessary because my crossovers are operating perfectly.There is a bit more to crossovers than the crossover frequency, but I'm not trying to change your mind about replacing the whole crossover. I haven't done it to mine and I'd want to see exactly what changes were made before making a decision. I have no doubt that there would be some differences in the overall frequency response curve, otherwise it would not be a different crossover.
I think you are on the right track.
As to whether your technician would have crossover caps, maybe, maybe not. They should be caps designed for crossovers and people usually don't stock those. Anyway it's easy to change out the caps later if you want.
I was informed that the phenolic diaphragm is made of a plastic material and obviously the titanium is much stronger and durable and would therefore be able to withstand vibration better. I am , like I said , very excited about this upgrade. I have noticed the new vintage Klipsch Loudspeakers such as the heresy the forte the chorus all have titanium material in their drivers in the tweeters midranges they’ve exclusively gone to titanium so there is definitely something here to doing this.The original “ Phenolic “ Diaphragms in the KG4’S K-74-K have a frequency of 1,800hz and the Titanium replacement K-74-K frequency is also 1,800hz so I’m assuming that the need to change the crossover is therefore unnecessary because my crossovers are operating perfectly.

Odds are you're gonna love them. They are more detailed, but the main thing I noticed when I installed them into my Klf 20s is that they are more dynamic. Songs that are dynamic really allow the speaker to strut its stuff now. Everything's much more smooth and silky up top. This was all before I upgraded my crossover which makes a minor difference too and is worth it.View attachment 1342791 OK , so I “ Finally “ did it and ordered a pair of Bob Crites K-74-K Titanium Diaphragms for my Klipsch KG4’S!!
