Hi Dramblys,
My Enabl treatment is still a work in progress right now, I have added the zig/microgloss alternating coats to the whizzer and also some zig to the accordion surround.
So far, the "presence" of the sound is definitely better but it seems that getting rid of the shriek in the upper frequencies (I'm guessing around 12-15 Khz) won't be dealt with through Enabl, these drivers get tiring pretty fast due to these bumps in the frequency response.
I have found out that some Dacron or fiberglass stuffed between the whizzer and the main cone does a pretty good job at taming the shriek, but not enough to make the drivers enjoyable for long periods of time.
I'm starting to think that the AN Super12s are fundamentally flawed, and will need huge amounts of work to play well.
Disclaimer: I am no professional at Enabl, and this is the first pair of drivers that I Enabl completely, so I might very well not have done all the things the right way...
I have a pair of Fostex FF165wk and another of FF125wk and as long as you don't ask them to play too low, they just smoke the Super12s.
As time went by and with experience, I have also become a believer that using fullrangers to reproduce the whole spectrum (30hz-20Khz) is a very difficult thing to achieve (if ever possible) unless you have a room big enough to accommodate huge horns (but then you run into all kinds of new problems), or you are willing to listen at low SPL.
Bass reinforcement below 100hz allows fullrangers to really shine.
I have used the Super12s in OB with dual H-frame woofers as well as in David Dick's recommended big box (the 5.6) and still prefer my FF165wk in metronomes (ML-TQWT) and the FF125wk in OB.
Hope you find my input helpful.
Regards
Nick

tell me please, do you notch those new Fostex, do they have unlistenable peaks?
I have not felt the need to apply any notch to these drivers, just toe them in a bit and you're good to go
I have a pair of Audio Nirvana Super 12 stamped frame speakers that have been in my system for a bit more than a year now.
.
Just for clarification can you confirm whether you have the Cast Frame, or Stamped Frame
hajj,
How big is your open baffle (ob) for you ff125wk ?
Tell me more. I've a pair and I'm not sure what to try, but an auditorium solovox clone is an option...........
