Hi Zogu,

Hi ,
Has anyone tried a tertiary winding added to a mains toroid as a cancellation winding ? This seems to work ok but probably best for dedicated amps for mids/tweets or compression drivers . A toroid on it's own SE (saturating) is ok for a tweeter and they're good up to 40KhZ if I remember correctly 😉

cheers
