RE: Sound stage

The Sonic Hologram, also known as the Sonic Holocaust was Bob's effort at canceling 'interaural time delay'.
This is when the sound from the LEFT side of the stage reaches the RIGHT ear about 1/2 millisecon d later.
The idea is to subtract the common R from the L and the common L from the R.
Polk had the SDA speakers which did the same thing by locating the presence drivers about 6" apart, which is about the distance between EARS.

Link to discussion of the SDA speaker and why it 'went away'. But still has a following.
Too much is never enough
