The 1st is a little unexpected, that the transition bump is killed is a bonus, the 2nd is more so, if one gets the line and the damping right the impedance rise at resonance can be almost flattened … a big boon if you are doing a passive XO.

Here the FF85KeN in a 10:1 1/4 wave aperiodic midTL, showing the dramatic reduction of the resonance peak if you get the damping right (less dense to more at the terminus). You might exiperiment with the plastic pipe and damping. (steel vrs plastic should make little difference).

Been a while since that diyFEST but IIRC you sent me the SeaHawks cap which is one of two in regular rotation.

Default Flattening the curve is popular right now.

That's pretty cool. I will have to give that a try. It will be interesting to see what it does to the impulse response etc.

I'm not the SeaHawk Dana. There was one sporting a SeaHawk hat. He apparently is a more socially tuned in human than I am. I need work on that. I think I still owe thank you notes to people for birthday gifts when I was 10. Don't tell my mother.

Two Danas at that FEST. Usually it is Daves, or Steves or Marks. :^)

MatsS64 - That is a very interesting design. I think Linkwitz and others have done something similar in the past by using drivers firing up into diffusers/waveguides.

Have you done any measurements?
