From an engineering standpoint you won't do better than a metal film resistor. Those are available on Amazon for less than a dollar each.And what do you think about upgrade the Resistor of a tweeter with lets say a "mundorf"? Is it the same as your experiment with capacitor? No change will happen? Thank you in advance
What makes that an "upgrade"?And what do you think about upgrade the Resistor of a tweeter with lets say a "mundorf"? Is it the same as your experiment with capacitor? No change will happen? Thank you in advance
Mundorf says so. Duh!What makes that an "upgrade"?
From a hifi youtuber stand point lolWhat makes that an "upgrade"?
All right thank you for your responseFrom an engineering standpoint you won't do better than a metal film resistor. Those are available on Amazon for less than a dollar each.
Generally, that means avoid it like the evil one.From a hifi youtuber stand point lol
If I hadn't watched Amir's videos, I would fall into this tendency of wanting to have things that have no scientific meaning.My biggest gripe with boutique parts is they have no datasheets. Just a shiny part, a high price and a tremendous marketing push.
He'll be glad to hear that.If I hadn't watched Amir's videos, I would fall into this tendency of wanting to have things that have no scientific meaning.
Last I saw, Pass uses wirewound resistors liberally. Not sure what you're asking here.What about non magnet resistors? I've seen Pass, Mcintosh, Herron, Nord, Decware use them. It seems to me they use them in
places they can find the value and if it's a high priority circuit. HP circuit in the path or shunting to the negative
circuit or away from the positive.
Please excuse my lack of technical terminology. I noticed that Pass had several in the F5 or 6 active XOs I have. I have had a few Pass
designs and one thing I can say with certainty; if a 1 dollar part will work and hold up. HE WILL USE IT. That is telling me something
about that type of resistor. I'm just not sure why he prefers it over others.
Nord on their revision D board has the same deal.
Later Mac pre amp are full if them.
I have soldered a few too. What a pain. It was a spec change for an OXO Pass unit. Tiny friggin wire.

That's a worthy goal. But I doubt most manufacturers are willing to participate.Since the criteria of 0.1 dB was almost reached with variation in the capacitor ratings, it would seem to me that the real benefit to quality parts is getting units that consistently meet their spec. Ultra-cheap mini capacitors like the ones I recently bought for a non-audio project regularly vary from their spec by more than 5%, which according to these measurements, should produce detectable variations. To me this says what we should be asking speaker manufacturers is, "how many controls do they use to ensure consistent parts matching and performance to speaker specifications?" Again, I am reminded of how Snell used to have each speaker's crossover and drivers manually matched to a reference model by adjusting capacitance or changing the number of windings on inductors. Perhaps we need a similar study of the real range of variation in driver performance for a number of manufacturers (when talking about suppliers like SEAS, Scanspeak, SB, etc.) to understand that maybe better capacitors don't matter, but accurate matching of capacitors and other components with drivers is measurably important. From factory tour videos on youtube it's clear that many (most?) higher-end speaker builders measure and match at least their drivers and usually, the finished speakers, but who doesn't?
They are wound with copper not a non-ferrous material. Most are iron/steelLast I saw, Pass uses wirewound resistors liberally. Not sure what you're asking here.
OK. I recall him saying he used garden variety wirewounds. Maybe the non-inductive sort if he was feeling crazy that day.They are wound with copper not a non-ferrous material. Most are iron/steel
This pic is not clear enough but I remember a few on the OXOs.
Nord uses them on the buffer and a Mac C2500 is full of the little critters.
For the lack of my techno jargon I think they're NOT affected (effected)
by parts that create a field.
I'll dig up a book and figure it out. Thanks. I'm just being lazy.
It's part of the story.I'm just not sure why he prefers it over others.
