Sounds similar to the effect from the old (original) Polk speakers (cant remember the model #) The ones that had separate and direct connections between the L and R towers. Each tower had separate speakers that were wired out of phase and cancelled the other speakers "phase shift" (or something like that). Anyway, this design produced the most uncanny effect I have ever heard! You had to sit in an exact "sweet spot" in the center but the sounds came from all around! It was pretty freaky man!

Good listening!
