Hm, I do not know men, but it des not work. Over the last few years I have tried the ordinal metal diaphragm 4 or 5 times and not with the Super Melquiades it is the most successful try but I still feel than it is not the sound that I would like to get.

The metal diaphragm is super fast and super transient, it has phenomenal “absolute tome” but at it higher boundary it has some issues that I newer was able to deal with. I do not know now describe this idiosyncrasy of it’s sound. Previously it was the certain harshness but not with the Super Melquiades’ dedicated channel when the S2 driver does not see the upperbass coil it stopped to be “harshness”. I have to add the amount of the “harshness” is very minor, close to be completely negligible (at least I have no one person beside my who have listened my listened room and who would note it), however it is there. So, with the dedicated Milq this “harshness” became overly nervosa-loaded transient. I think it has something to do with some kind of cone’ resonanses at ultrasonic level, but not too high (20-30kHz like with most metal domes) but at much lower frequency – I would say ~15-20kHz. . This Vitavox S2’s reso-nervosa it sound VERY impressive (in fact impressive like nothing else) but this reso-nervosa at HF is identical across all music. I certainly do not appreciate the last sentiment….

I still like what the fully metal diaphragm does but I doubt that I might use it as is. There are 3 strategic directions that I might take to make it working, if I will be perusing it.

1) I might go for slightly larger horn, perhaps 330Hz that will set the driver deeper and will roll off some HF. I do not partially like this direction as with the deepening of the horn many other problems will pop up.
2) I might try to find some ways to mechanically damp the cone by tinning the back chamber. This is very nice direction to go but it might not be useful and I have issues not with HF knee not with LF knee.
3) I might very slightly to change the mass of the diaphragm, perhaps by spaying it, or painting it, or cover it with the saliva of a pregnant adolescent camel, or you name it. This is certainly the most interesting direction but it is completely unpredictable, not controlled and only God knows where it might lead and what I might end up with. Perhaps Bud might saddest something toward to this end…

Anyhow, will see…
