Titanium Diaphragm installation

In this short video, Michael demonstrates the installation of a Titanium Diaphragm into a tweeter. It's a simple process, but sometimes the visual is necessary.
Klipsch Forte I - Crossover "pile of parts" for the silver level crossover rebuild and cap testing.
มุมมอง 7983 หลายเดือนก่อน
Lets measure ESR and capacitance in the Forte I crossover rebuild. HINT... the right tools make or break your results! :)
KG 1.2 - PT 7 - ESR (equivalent series resistance) and Capacitance measurements and why they matter.
มุมมอง 4663 หลายเดือนก่อน
Why do the right measurement tools matter? In this short clip, Michael demonstrates some of our testing measures. While we DO listen to the speaker after everything is rebuilt to ensure they sound amazing, we also get ACTUAL measurements in a live setting to SEE all measurements are within the correct limits.
KG 1.2 - PT 6 (rebuild comparison and reassembly w/ crossover reconnect)
มุมมอง 2503 หลายเดือนก่อน
In this quick video, Michael compares the original crossover with the rebuilt crossover. He also reattaches the rebuilt crossover and reassembles the KG 1.2.
KG 1.2 - PT 5 (Spectrum Analyzer analysis of rebuild)
มุมมอง 1403 หลายเดือนก่อน
Michael explains, very simply, the Spectrum Analyzer results for the KG 1.2 crossover rebuild, and what this does to the sound you will hear as a result of the exchange. .

Michael goes over crossover terminology for the KG 1.2. rebuild.

In this brief video, Michael is removing the grill and showing you a few details about this awesome little speaker!
Great video. Short, sweet, and to the point. Just upgraded my Quartets with the silver cap set. The titanium tweeter diaphragm is my next thing so this was super helpful
Nice instructions.. I’m going to have to call you about my rebuild of my Tangent 400’s. I can’t (didn’t mark them 😢) remember POS/NEG on the k-24-k woofer. Keep the vids coming guys!
You don't clean the magnet gap when changing a diaphragm?
Why is the ferrite core being loose, an issue?
@@davidhamm5626 if the ferrite core cracks, it will reduce the inductance of the inductor considerably. This will change the characteristics of the crossover in a way that will almost certainly be audible.
@@ScottGrammer Okay, I understand now, thanks !
Your kitchen is way cleaner than mine =p lol I too needed more counter space for projects other than food
To be fair, this is the kitchen in my shop building/break room so it stays more usable than the one in my house!
@@OfficialCritesSpeakers same =p
Replacing film caps with electrolytic bipolars? In almost 50 years of working on audio gear, that's the first time I've seen that done. I know that Crites and Klipsch have sort of a hate-hate relationship. On the Klipsch forum, just using the word "Crites" in a post will get you a warning from the admin. And, let me say up front that when I built my current speakers, I bought and used a pair of Crites 3636 autoformers, and I absolutely love them. But what you're showing here might be a bit misleading. Not the "pile of parts" bit, you're right about that. That crossover looks like a hot mess. Paul Klipsch would have had a fit. It looks like the insides of a Sanyo rack system speaker from the 80's. The ESR issue has me wondering. First, did Klipsch use crummy Chinese film caps, or is there some other reason that the film caps have a higher ESR than the bipolars? It should be the other way around. Second, how much do these small amounts of ESR make a difference in speakers with eight and 16-ohm drivers? Electrolytic bipolars, like all electrolytics, become leaky with age, and this leakage can result in serious changes to the sound of a speaker and can result in damage to HF drivers due to lows getting through the leaky caps, That's why I always replace bipolars with GOOD film caps, like Nichicons, and if necessary, add a bit of series resistance to account for the almost always lower ESR of the new film caps. When I recapped my Smaller Advents from 1972 (my bench speakers), the new film caps eliminated the obvious low midrange information that was going to the "fried egg" tweeter, but it made them a tad too hot above 7K. A one-ohm resistor in series with each cap toned it down a bit. Note that these are four-ohm speakers, and so ESR is more important.
We have been working on these speakers since the early 2000s and have rebuilt thousands of crossovers in this time. The results in ESR data have been consistent in showing that after about 20 years these caps all have high ESR. I can’t speak to the quality of the parts that Klipsch may have used initially as far as how they tested when they arrived at the factory, but I have reams of data showing how they test when they age. This additional resistance when added to the circuit does indeed change the crossover point to some degree. In testing with an audio spectrum analyzer before and after rebuild using simulated driver loads, there is a notable difference pre and post-rebuild, and customers really appreciate the sound improvements when they reinstall the crossovers after rebuild. Most often I get comments such as “this was like lifting a blanket off of the speaker”.
During the time that these were built, I do no think the caps were " cheap Chinese junk", but were , as we have seen, the best parts available, at the time. Also, many of the speakers were designed using tube amps amps. and pre-amps. So, for that point in time, they sounded wonderful.Look at the frequency responses, as designed, they are fine for the times. When using digital ,electronics, you are asking the speakers to do something that they were not designed for.
It would be great if you could show the ESR measurements from the old "oil can" caps that are in many Klipsch speakers, such as the AA crossover.
I will be adding more videos as I am able to get them done. I have thousands of caps that I have removed from crossovers and I will do some comparisons on those old caps in that series of videos.

Keep em coming 👍 thanks
Thanks for tuning in! Hope we can produce lots of videos that both educate and are enjoyable!
