Was about to sign off but I had to put in one more comment.
No doubt some well done field coils can out do alnico magnets, no argument there but please note the WELL DONE part.
I have known and bought and built many horns from Bruce for years, I think he was saying the ferrites were just as good so some of his customers could be able to afford his speakers and may recommend the ferrite for them. I think towards the end before he retired he went to field coils and left permanent magnets for dead anyway though.
I would like to say that if anyone likes an always inferior ferrite magnet version of a driver there is something really wrong with that picture. As I mentioned the drivers need identical cones or diaphragms and fully charged alnico to make a fair comparison.
Now I have heard of some out there saying there may be a weird phenomena
that some ferrite magnets work ok and sometimes actually better than alnico with certain solid state amps. I don't know about this, I have not experienced it myself but I am actually very open minded even though I have very strong opinions.
If somebody is willing to demonstrate or explain their position, I am always all ears...on any audio topic.
