There are some advantages in S3 design that feel might be beneficial for sub 1K use of S3 drivers. The S3 had more accurately made output channel. I think it shell more benefit FH but who knows… Also, and this is a very big for me the S3 has the diaphragm plate decupled from the back plate. This decupling is very bad thing in S2.

Among two new Vitavox S3 drivers that I got one was excellent but another was something that I call Black Hole driver. A “Black Hole” driver is a situation when your driver has a fully charged magnet, not open voice coil, not fractured diaphragm but do not produce any sound. So, my second S3 was Black Hole that sucked voltage but returned nothing. That forced me to fix the driver and upon dissecting it I realized that I was wrong presuming that in S3 the diaphragm pressing plate is decupled from the sources of external force – they are not. This is a big foolishness on Vitavox’s side, well it is what it is…. Still, I run S3 on my LF swapper and it goes quite lover then S2 before it become buzzing - a good sign generaly....
