hi mr. donvk,

i'm still analysing this thread and merely pop up to say that it is very interesting work you do here!

Thanks, this is a "play" thread to design something, build it, and test it to see how close the prediction was. Same full range driver used in designs from subwoofer to horn.

do you read the paper from Bruce Edgar Midrange Horn?

without any tricks your horn should go to 4..5kHz without problems

Hi Kay,

Thanks, I have read (inspired by) the Edgar midrange tractrix paper. I also tried his "leaky" throat trick using a gap and foam. At the time I concluded the PC83 motor was just not strong enough. I did manage to get to 5KHz but it also had a dip that I needed to EQ out.
