Are you asking how to figure out the angles or how to arrange to
hold the speakers in position?
One pattern you could use with 30 instead of 32 speakers would be to put
speakers at the midpoints of the edges of a regular dodehedron. (there are
30 edges). This is a quite regular pattern though t
Hi Steve.
I understand your problem. I have a similar one; in my case the
calculations and the installation were easy, but I'd like to measure
the exact angular positions of the (installed) loudspeakers.
First you need the angular positions of the loudspeakers from
the listening spot. It should
There's a laser distance measuring device from Bosch with built in incline
measuring aka electronic level. Not too expensive and useful for many other
things as well.

I always meant to complete a speaker position detector using either a
Soundfield (or Bramha or Tetramic). By feeding each speaker in turn with a
PSRB and cross-correlating that with the outputs of the mic both the
position and the distance of each speaker could be acquired. If you don.t

Assuming the room walls are
I have used the Bosch laser measure in a variety of contexts with great
results. Assuming you have the horizontal angles marked out (which can be
easily done on paper with a floor plan of the room), getting vertical
angles and speaker distances is very fast and straightforward. You'd want
to be s
