I had forgotten - something I'm getting alarmingly good at! Yes, I've read the discussions, but thought I'd give them a whirl as a small cheap experiment, as opposed to the huge expensive experiment with the TADs/JBLs. I'm hoping that the lack of a whizzer cone and the addition of a phase plug may sort some of that out, to say nothing of the alnico magnets. There's also a filter approach to the peak.
Worst comes to worst, I may put them in a Tractrix horn and use them for midrange only.
Thanks for the input!
