Its just a bit strange being so green/confused at something I've been this into for over 30 years lol. 1 Quote Link to comment Share on other sites More sharing options...

geoff. Posted June 25, 2019 Share Posted June 25, 2019 Ok, again, so how much of a difference does the coil make? I (think I) have read that air-core is better and I thought I had read not to get caught up in the gauge of wire. Quote Link to comment Share on other sites More sharing options...

I (think I) have read that air-core is better and I thought I had read not to get caught up in the gauge of wire. Not so much. Wire size directly affects the resistance of the inductor. Iron/steel cores increase inductance and "pull" the magnetic field very close to the inductor, reducing interaction between 2 inductors. The increased inductance means less wire may be used further reducing the resistance of the inductor. The negative of iron-core inductors is that the core will "saturate" at some power level and then the inductance changes and then changes again with more power changes. I remember a statement from Mr. Paul where he said the Khorn's woofer inductor saturated at 63 watts. 1 Quote Link to comment Share on other sites More sharing options...
WMcD Posted June 26, 2019 Share Posted June 26, 2019 Sixty-three watts, huh. That is 18 dB above the 1 watt level or 105 dB plus 18 is 123 dB which is a little above the rated max output of 121 dB (equating electrical dB to acoustic dB). Therefore it makes sense. Then again someplace he said you can run the K-Horn without that inductor. It also shows you don't need more than 63 watts of electrical power which is dangerously loud anyway.

ricktate Posted June 26, 2019 Share Posted June 26, 2019 I changed mine from Type AA to Type A and got the caps from Parts express...Bob Crites also has the right ones. Quote Link to comment Share on other sites More sharing options...
ricktate Posted June 26, 2019 Share Posted June 26, 2019 Sorry tried to fix my post would not let me. You can get the right values wit 2 capacitors hooked together if you cant find right ones. Quote Link to comment Share on other sites More sharing options...

SQ tracks with type, and quality of build and materials. Want long term reliability? Make sure it's hermetically sealed. Teflon film caps DO take in the multiple hundreds of hours to break in. Not hyperbole at all, and a long wait, but once they do break in they "get out of the way" sonically like nothing else. Makes for a LONG evaluation time though - many don't have the patience to do it but rewarding in a lot of cases. That said, I'm not sure I would want to go TFTF for crossovers on a horn speaker, though. 1 Quote Link to comment Share on other sites More sharing options...

Even if you wanted to, they don't come in values high enough. You can go metallized, but then why bother. Quote Link to comment Share on other sites More sharing options...

Since he designed the Sonicap, he might provide some interesting input. cs@soniccraft.com @DeangSo I emailed Jeff and he told me my oiled filled 43yr old caps probably sound as good as when they left the factory. how can this be remotely true????? 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted June 27, 2019 Share Posted June 27, 2019 I would say possible but not likely. They consistently measure pretty bad, and many are leaking oil on the boards. So, what was his answer to the question? Quote Link to comment Share on other sites More sharing options...
