Shakti Hallograph Sound Field Optimizer


Has anybody personally experienced this "accessory" - The Shakti Hallograph Sound Field Optimizer? I am really intrigued but skeptical given the price point. Any guidance would be appreciated.

From what I understood from talking with the maker, speaker type can make a difference too. Boxed monopoles are OK. Dipole types, not so much...
