Tweeter Capacitor Upgrade (Coincident PREs)

hi @bache,

Sorry, I meant to say the Audyn TC 0.1 uF was $20, and I was recommending it as a bypass.

For bass caps, you can seriously go cheap. :) It's still a huge improvement.

Old capacitors ESR shouldn't be an issue, because I can adjust HPF cutoff frequency by potentiometer.

In shunt caps this can have really bizarre effects, so I doubt it. :) Depends very much on your amp.

hi guys i know this isn't related to the thread topic but i don't feel like making a new thread ... should i seriously be considering coincident pre? i live close to isreal so auditioning is no problem... i had a bad experience with him in the past but my line of thought is i shouldn't let emotions get in the way of owning what is potentially a rock solid speaker that would push above its price point.

i was considering the pre vs wilson audio specalties sasha daw, avantgarde acoulstics duo xd, and maybe kef reference 5. possibly a used jbl d670000... theres been a few for sale for under $40k.
ive also considered a few active systems but i dont think here is the place to ask about those types.

Let me add a little:
If you mess up the 2nd pole in the low pass filter, you can drop the impedance through the area above the crossover point, which actually doesn’t change your LP frequency response very much, but if your amp has very much output impedance at all, it will drop the output. Weird right? Seen it 2-3 times.

If you use a crossover simulator, you'll see this in the impedance graphs, but not the frequency response graphs, unless you have one that lets you simulate amplifier output impedance, then it's super obvious.

Best,
E
