jimjimbo Posted January 27, 2018 Share Posted January 27, 2018 Soliciting some opinions on what folks might think about the comparison between the OEM 2.5mH inductor common to many of the Klipsch crossovers (such as the AA), and a much larger ERSE inductor such as this 16 AWG unit. Just wondering. https://www.parts-express.com/erse-super-q-25mh-16-awg-500w-inductor-crossover-coil--266-908 Quote Link to comment Share on other sites More sharing options...
avguytx Posted January 27, 2018 Share Posted January 27, 2018 I've not personally done an audible comparison but I ordered the 18awg version of those. About half the price. I debated on the others but after comparing specs, just didn't think I'd tell much difference. Quote Link to comment Share on other sites More sharing options...
MC39693 Posted January 27, 2018 Share Posted January 27, 2018 (edited) I did not do A/B tests but have used the Erse inductor in a brand new E crossover I built, including Jantzen Silver Z caps and auto transformers from Bob Crites. All worked well with good results. The inductor does take up some room! Sorry, the crossovers with these inductors are in 1980 Heresy with all original drivers.

jjptkd Posted January 27, 2018 Share Posted January 27, 2018 I just installed a pair in my custom 362's but added acoustic foam at the same time so hard to say which had the largest impact but there was an improvement. Quote Link to comment Share on other sites More sharing options...

The Erse has lower DCR than the OEM part -- over an ohm. It's not much, but probably enough to hear. They sound different to me, but hey, I hear all kinds of weird shit. 1 Quote Link to comment Share on other sites More sharing options...

The Erse 16awg is almost half of the 18awg DCR, and (thanks Dean) also much lower than the OEM. Yes, the 16 is twice the price at about $20, but maybe worth it.

Blvdre Posted January 28, 2018 Share Posted January 28, 2018 Madisound offers a 15 AWG 2.5 mH for ~$16, equivalent DCR. https://www.madisoundspeakerstore.com/steel-laminate-15-awg/steel-laminate-2.5-mh-15-awg-inductors/ Quote Link to comment Share on other sites More sharing options...
Deang Posted January 28, 2018 Share Posted January 28, 2018 Those are junk. I used to use those until they started showing up with loose windings, and I would have to tap them on the table to get the plates lined back up - so I could get the screws through the holes. The Erse coil is much better. Quote Link to comment Share on other sites More sharing options...
BeFuddledinMn Posted January 28, 2018 Share Posted January 28, 2018 For what it’s worth, I did a lot of inductor testing on the Klipschorn a few months back (see my Klipschorn woofer & motorboard comparison post) and I can tell you that there are measuraeable differences. Whether anyone can hear theses differences is another matter. Clearly, large changes in inductor value ( of any inductor type) do make real differences both to the ear and in measurements. Of course, in the Klipschorn, these changes really require corresponding changes in the midrange network and integration as well in order to ensure any potential real “improvement.” Your individual room acoustics will have a real impact on this as well. -BefuddledInMn Quote Link to comment Share on other sites More sharing options...

Don Richard Posted January 29, 2018 Share Posted January 29, 2018 Changing the resistance of an inductor changes it's Q. That affects the performance if the filter, but how? Quote Link to comment Share on other sites More sharing options...
