For small areas, or central listeners, I do think there is a good
argument for not over egging the pudding with too many speakers for
low order material. But I am not at all convinced, based on
experience, that this is true when dealing off centre listeners in a
large area such as a concert since
Thank you for all suggestions!
I am also aware of t-design [1] for even distribution.
Does somebody have practical experience with those, except for virtual
loudspeaker arrangements?
Fons' 1+6+8+6+1 seems to be a good and easy to mount start.

I must confess that I don't know much about what you are discussing
about, but I think I read in one of the posts (that I already have deleted)
that there is no need to place a lot of speakers directly above, as our
localization is at it's worst in that direction.
However, I have always thought
Hi Eero,
Al revers amigo. I dont know how it works with ambisonics and soundfield
reconstruction but basically generally speaking your ears cant tell the
difference if a speaker directly overhead is half a metre this way or the
other - in effect your ears have lower resolution straight above so
Hi Augustine,
Whilst it is generally said that that our angular acuity is better
on the horizontal plane, this way of expressing things is, frankly, a
snare and a delusion since it only applies when the head is upright.
Unless your listeners are restrained using something like the infamous

Hi Dave,
Interesting - but we cannot comfortably tilt our heads on the side of our
neck so that the horizontal plane becomes exactly equivelant vertical plane
so even with these head movements I localisation directly above would be
less accurate other directions (I assume - I would like to see

Decades ago, I was working on a project to find the best
way to equidistribute a large number of points on a sphere.
We were looking for random unit vectors.

containing a seed to see if the seed would sprout and grow

Looks great - all I would say is you dont need too many speakers directly
above the head as our localisation is poor there anyway.
