Sabai, I acquired an Audio Pulse Model One, a digital time delay system that had three (3) sets of outputs (L and R). The user could select among a small club, a medium size auditorium or large concert hall. Each set of channels, front, side, rear, output the reverberant decay information associated with the size of venue selected. Separate amplifiers and speakers were necessary for the full system; however, inexpensive amplifiers and speakers could be and were used since the Audio Pulse Model One produced "non-coherent signals" and only up to 8 kHz for the ambient information channels. This time delay system, with all three sets of ambient channels, was capable of producing a soundstage as big as Kansas, much larger than the room, perhaps 30 feet deep in some cases. Note, the volume of the ambient channels relative to the primary speakers was much lower so as not draw attention to themselves.
It was later on that I discovered how much information is actually buried in recordings, that even very large and expensive systems fail to reproduce, and what was required to extract that buried information for 2 channel stereo. The real ambient information was there all along, we just couldn't hear it!
