MochaMike, yes you are correct it would not be the “softness” but rather”liquidity”. Still what you are taking is applicable for the paper cone 4 to 15" drivers not compression drivers. Who knows how the compression drivers will react.

To the rest folks...

Flasks. I really do not know how the electromagnet will behave and how it might sound. I have nailed down for the project the following objectives:

1) Trying to deal with some very specific Vitavox S2 characteristic by levering the magnetic force and consequentially dumpling the cone by this. I really do not care about the dropping the sensitively of the driver as I have 12dB to burn in the Super Milq upper frequency channel.

2) Investigating if I would be able to find “different” current PS for the S2’s electromagnet in order to “liquidity” the S2 upper region.

3) Investigating if the rearmament S2 magnet combined with complementary field coil might be an interesting direction to go.

4) Eventually trying my long time idea of active modulation. The idea consists of having 2 field coils modulating 10% and 90% of the magnetic force (or 10% field coil and 90% of the permanent magnet). The 90% coil is driven by a DC power supply. The 10% coil (or even less) is driven from a regulator 6C19P/6C33C with an ultra fast aerial amplifier (around a HF penthod) and using the source form the Melquiades output. The idea is to see if by binding the magnetizing current in the real time would provide any interesting effect. Theoretically by increasing the spread of the regulator and minimizing the size of the 10% coil it might be possible not only completely compensate the flux modulation but also to gain some dynamic. It would be cool to try to souse the field coil regulator form a different dedicated amp and to delay the main amp.. Here we go…. fantasies, fantasies ….

Anyhow, this all juts theories and I really do not know if it all worth to try. I took the S2 apart (the pictures will be posting soon) and tried to come up with the concept how the field coil might be implemented. Men, not I can seen what the Cogent’s boys when there and how much work it might be, even if I have the driver base is ready to go.
