If driver impedance doesn't matter or shouldn't be used how then do you determine the size inductor one needs? Cabinet and driver size? Cabinet tuning? I understand the need to cap the woofer and that the folded horns will likely have their own built in frequency response limitations but what about direct radiator speakers like the Cornwall, Chorus, Heresy etc? I ran a calc using an 8 ohm tweeter, 16 ohm mid and 6 ohm woofer and came up with 2.4 mh. Quote Link to comment Share on other sites More sharing options...

I just always assumed he did -- since he backed the 1mH out of the original value of the low pass coil. So, here is what he has to say about it, and I'm not going to pretend that I understand it all. OK, I do not remember where I came up with 6 ohms for the K33 but it might have been from that old post. I will read more thoroughly later.

As well you should -- that's why I built them that way. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted December 24, 2017 Share Posted December 24, 2017 so I have K horns and La Scalas. Any reason to use a smaller inductor for the La Scalas? Quote Link to comment Share on other sites More sharing options...
LalaWoots Posted February 12, 2018 Share Posted February 12, 2018 Would these work with Heresy industrial speakers?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
