Hi John, glad that I could help. I hope the reconing

went well.

I had an internet problem , so this is why I was hard

to reach.

I'm glad that I can help you get those Fertin.

How do the (much) cheaper Fertin drivers (BFA20T, ~350€) with "normal" magnets compare to those using fiels coils?

[lrntglls]

Having heard both but not in the same setting.

The 20S (ferrite) magnet were in a TL box;

the 20EX were in open-baffle. Completely different

sound ; the 20EX much more dynamic and detail and livelier

sound. When you compare the two, they are really different.

But in a backloaded horn the 20EX would give a nice sound.

You have a guy who built a Mowhorn with the 20S and he's

quite happy with them.

I have a pair of 20S in the box; too lazy to build a backloaded

horn to put them in.

The 20S would make a good speaker, the 20EX is just much

much more of all. The choice is vey easy to make:

you have $$$ go for the 20EX, period.

[lrntglls]

Sorry, Mauhorn. Both would go pretty low in a backloaded horn:

around 35hz. With no crossover, no tweeter and a nice

set amp; that could be quite interesting .
