The Ambi-5 Auditorium Decoder. I have a PDF of an Audio + Design leaflet which somebody sent me. If people want it I can place it on my Google Site for download. However, it just says: "The Ambi-5 produces five loudspeaker feeds arranged as a regular pentagon with loudspeaker spacing of 72 [degs]. The rotated output gives a clockwise rotation of 36 [degs]. Cascading two Ambi-5's will generate a 10 loudspeaker matrix of 36 [deg] angular separation." An addendum states that the Ambi-5 was used by the Cure on their USA tour. I have no idea when that would have been.
