Yes, I have both the DS 1448 midbass drivers and the original DS 1428 midrange drivers. Still using my old Fostex T-925a tweeters.
Since I'm still raising a family I couldn't justify spending on a Tungar power supply for the field coils. So I was using a couple of the pretty good old Radio Shack DC supplies for a while.
And then Pavel-whom you may have met over at Bruce's why back when-designed these tiny little cards that are a current source. I've got modular 20V supplies that can each driver two of the current source cards to maintain a constant 12V to the field coils regardless of what is happening in the VC gap. They are very nearly the quality of a Tungar.
It makes no sense that a field supply would make a big difference but everyone I know that has compared them agrees.
And simple 1st order network with 10Ga inductors and I charge coupled the Soviet PIO caps...
