Possibly ambisonics is different - but not all multichannel audio uses
ambisonics - certainly with vbap for example  if your speakers are wide
apart you don't want a big gap when panning between them then  wider
dispersal would be advantageous if the speakers are very close together I
could see it would introduce coloration when the directivity of the
speakers overlapped - with wavefield synthesis the smaller the gaps between
speaker cones the higher frequencies can be succesfully spatialised - so I
guess for wfs more "pinpoint" directivty would be preferred - I may also be
wrong ! For creating true walk around 3d soundscapes with no sweet spot for
me a useful tool would be a driver which would be a sphere which put out
sounds in all directions (360) - because thats how sound often propogates
in real space (eg a twig cracking up a tree will not just put out sound in
the 180/90 degree space on one side) The dispersal pattern of speakers isnt
often considered when building these kind of systems so its an interesting
topic !
