Carver's system, otherwise known as the 'Sonic Holocaust' was a way to clean up the stereo image.
When recording say....just for example.....a singer and band with a pair of microphones, each mic will get information....somewhat time delayed, perhaps, from the opposite side.
Sonic Hologram will subtract right side information from the LEFT and left side information from the RIGHT. This eliminates the 'crosstalk', if that's the right word.
Polk did the same with speakers a few years later, by having a pair of midrange drivers about 6" apart horizontially. The distance was decided by the space between ears.
They fed signals between speakers to accomplish the same 'subtraction' and used the distance between drivers to account for the time delay.
I never heard the system. I'd like to hear it with headphones.
