Can anyone identify this inductor?


Its a speaker crossover from a well known brand. Most coils on it are standard air coil style... but one looks like a transformer - wound vertically around a HUGE iron core which protrudes out the sides, then varnished/sealed and puttied to the board. Stamped with the company’s name on it. (All other components look sourced).

I reached out to the company waiting for an answer, so I won’t mention the name. But I don’t think they will reply.

Iron inductors seem like a no-no. In fact, I got huge coherency improvements by taking anti-static and EMI measures on it with some usual hi-fi tweak products. I do not know if they even tried to orient it correctly.

Anyone know? cheers

I've got the parts but they were slow to arrive and now I'm in the vacation season so I haven't done the work yet.   I'm chaning all the inductors in my crossovers to wax/foil inductors. Some existing are iron core, some are not.   Replacements are Much larger.  the heaviest ones weight just over 5 lbs.  

Upgrading your inductors (and caps and resistors) is a fairly expensive but quite useful upgrade to most speakers under $50k.  And a good upgrade for many more expensive speakers as well.

Measure the inductance and order 2 upgraded replacements (one for each speaker).  While at it, upgrade other components on the crossover.
