How do the lf drivers flanking both sides of hte waveguide of hte larger line array units compare to the d'appolito concept?  Maybe my understanding of hte concept is flawed, but from the turbo tms3 onwards to current pro box design, there have been successful examples.


Same idea Randy, only a horizontal dipole.  If the center lobe starts to collapse, you lower the XO point of the mid drivers slightly, to fill in the blank in the center of the pattern.

This is a really a fundamental concept that everyone should wrap their heads around.  It applies to antennas, speakers, light sources, etc.

Hi Mac,

I would not be surprised if you do get a pattern flip with that horn.  A horn will only have pattern control when its mouth dimensions are large in respect to the wave length its trying to produce.  In this case it’s mouth is wide but not particularly high. So as you go lower the vertical pattern control is lost much sooner than in the horizontal, i.e. the pattern flips.
