Oicu812 Posted December 18, 2018 Share Posted December 18, 2018 I got this on offerup for $15 plus shipping. I have no clue what this thing is, and google searches proved fruitless. It just arrived, and it is cast aluminum (instead of the black plastic that I was expecting). I thought I would use a Klipsch pro driver to play around with it, a k128013 out of a KP-3002. What is this unusual horn? Anyone know? Quote Link to comment Share on other sites More sharing options...

Chris A Posted December 20, 2018 Share Posted December 20, 2018 I'd call it an "acoustic band-pass diffraction horn...with higher order mode (HOM) suppression". In real life, it's probably a pretty severe HOM generator--as all diffraction horns are--above a certain frequency corresponding to the width of the slot(s). If you use the horn below 4 kHz, it should probably avoid the HOM "cut-on frequencies" that sound like frying bacon. Chris Quote Link to comment Share on other sites More sharing options...
