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

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 🙂
Just for clarification can you confirm whether you have the Cast Frame, or Stamped Frame
Yes, they are indeed the stamped frame ones.
I have added heavy bitumen strips to the outside of the basket legs as well as some felt to the inside...

Honestly. The best solution would have been to tell David, that you weren't happy with them, outlining what you don't like and you could have replaced them with another model or even got your money back.
Are the stamped 12's even available anymore ?
I thought I heard they went to all cast frame models .

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...........

This thread seems obsolete as the Super12 Steel Frame is out of the line.
But I would like to know reports from the current Super12-CF.

Hey Norman, get yourself some cardboard and start trying ideas, you will have a lot of fun and learn a lot in a short period of time. It only takes about 15minutes to build an open baffle out of cardboard. Then if you are happy you can go ahead and build it out of wood
