Hi all from Italy!

@kortland

I am into fullranges, the compression drivers I never tested.

I like Sica 12d, they have copper faraday rings on the pole piece reducing a lot the distortion!

I read al lot about (cheapo 20cm driver) Beyma 8agn in a horn called "Viech" but no one ever mentioned that this driver has a copper ring on the pole piece, too. Not even the manufacturer mentioned it anywhere.

I saw it after I perforated the dustcap for ventilation purpose by hazard.
