Sounds similar in concept to the Phantom Acoutic Shadow that Nelson Pass designed about 20 years ago. It looks like it replaces the simple mic, preamp and amp in the PAS with a mic and DSP for processing.
The PAS idea was to cancel the pressure wave at the tricorners of the room where they start. AHC at Stereophile at the time did a review. They came in pairs and went into the front wall corners of the room.
