      "Another thing that is interesting to try is to have some speakers outside the angle of the main stereo speakers and put the L and R signals in the far left and far right speakers(respectively)
      with a 17 millisecond delay. This is about the delay of the first
      reflection in an ideal concert hall situation. This will produce
      a HUGE sense of space--much more so than the "soundstage" that High End audio likes to hear generated out of out of phase signals."

      I came across these links that describes the SME ESL63 setup, that uses 4 ESL63s, with 2 facing sideways at 90 degrees to the main ones and firing outwards. The speakers themselves were also heavily modified.

      Since I had an extra pair of ESL63s on hand, I've tried this, seems to work, a more spacious presentation of the music, but I have not measured anything yet.
