I did some Googling, and the closest thing I could find was info on constant voltage crossovers or amp (CMOS) design with lots of math. Nothing of any educational benefit comes up when I type in voltage transfer curve. Is what Bob did checking the VTC? Could you explain it to me like I'm 5? bascially what happens in a network (balancing network; not a crossover. a network has a crossover and gain adjustments in it) is that it takes the input voltage and changes it to feed the correct voltage and the correct frequency to the driver. this passing thru of the voltage and frequencies to the woofer, mid and tweet is called a voltage transfer. 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted August 18, 2016 Share Posted August 18, 2016 lol, well, I've been accused of that plenty - so if not for me, then everyone else - because honestly, when the issue of capacitor choices came up, all I remember is the "salt and pepper" bit. You just didn't seem to get much excited over the capacitor thing. Quote Link to comment Share on other sites More sharing options...

You just didn't seem to get all excited over the capacitor thing. ok the rest of the stories...on the resistor part i mentioned that you had to make sure that the impedance was linear in the passband and that you could adjust the level of the tweet above 7khz because i had gotten lucky and it attenuated linearly.....later on we were talking and i mentioned that you had to be careful if you used caps that were other types cause it could affect the freq response....thanks mr paul harvey. 1 Quote Link to comment Share on other sites More sharing options...

Deang Posted August 18, 2016 Share Posted August 18, 2016 I know something is going on with different capacitor types because it's pretty easy to hear - I just never thought it was FR because we don't have published curves showing that. The only curves we have are curves that show there isn't any difference, and so I've caught a lot of heat for "hearing things that aren't there". Bass baits; something shiny?

Is this true for all ouput levels? Just wondering if there is a difference when your blasting the walls down. JJK Quote Link to comment Share on other sites More sharing options...
Deang Posted August 18, 2016 Share Posted August 18, 2016 There is no way you can do any of this without a reliance on math and measurements. You can't design an amplifier "just by ear". Once you've established a baseline, you can tweak by ear. Pass is a genius, and though he might not be "chasing numbers", I believe they are so ingrained into his psyche, that I'm sure he has a very solid list of dos and don'ts when it comes to any of his designs. Mixing L-pads and autoformers is a bad idea, for the reasons Roy already stated. 1 Quote Link to comment Share on other sites More sharing options...

Maybe go back and read what Bob said about how he determined what a "correct" AA build should measure like. What you're describing with your Dad is pretty much what Bob did. The old guys in the industry often wrote about the damping properties of wax and oil. This stuff can still be found using Google Books. Why did PK specify "oil filled" capacitors?

JJK I can drive my Jensen and Jupiter builds to levels that I simply can't with a metalized polypropylene build, so I would say yes. Quote Link to comment Share on other sites More sharing options...
mark1101 Posted August 18, 2016 Share Posted August 18, 2016 So why do people like the AA network so much? Quote Link to comment Share on other sites More sharing options...
Deang Posted August 18, 2016 Share Posted August 18, 2016 I explained that earlier. 1) It's the sound they've grown accustomed to. It's a subjective preference. 2) Like the Type A, it "opens up" very fast with very little power. 3) At low to moderate volumes, in average sized listening rooms, it "gets out of the way". An "average size room" is any room half the size of yours. :-) All I know is that I like the sound quite a bit after I build a pair and hook them up. I do have a strong preference for my builds, but hey, what would anyone expect me to say? Quote Link to comment Share on other sites More sharing options...
