• 24 channel line array
• Plays the role of a scale model of the   disc, though it is not
• Diametral section of the disc
• The 3D effect of the disc is projected on a plane

The picture shows a 24 speaker line array which we are using now as a sort of scale model: it’s length is three meters just like the diameter of the designed final structure, and the heigth is 4meters as well. So it can be seen as a diametral section of it.
The choice has of course a logistic reason. The line array is supposed to produce the same kind of focalization of the disc, but limited to a plane containing the array itself. So for example, fo the listener staying here in front of the array, a virtual source will be possible mooved from left to right, but not from front to back, which will be possible instead with the full disc. For the line the focus is represented by a ring going around the array itself, whilst for the disc it is a little sphere. Consequently, the sound inflow in the environment is very different from the case of the disc,sound is much more dispersed and the possibility to create a surrounding silent volume become impossible.
This is the HW driving the array: description...
This is the whole system.
