IMO Isn't all this just a case of what's old is new again. Trying to revisit memory lane soothes the soul of some, but to me it's a bit like walking backwards.
Just adding more copper wires and another noise source isn't it. Besides electromags are not very green are they? I say cut all the wires!

Actually I love the idea of a field coil transducer but alas all of them that I have found are insanely expensive. I don't care what color they are I like the ability to tweek the driver parameters with change in field current.

hi
Which parameters are those?
I imagine they affect many with a changing B product.

Field coil drivers, if properly built, designed and employed, stand a chance of being the highest fidelity drivers in existence.

I will not share why I say that, but to those who understand the issues of a standard ferric, alnico, neo or whatever kind of 'permanent magnet' driver that may be considered..those folks know that the field coil design has some serious advantages.
