Left speaker to Right shoulder. Right speaker to Left shoulder. That's all.
My local AudioNote dealer does this with a few systems setup there. In some ways it works, and other ways imo it can be confusing how it sounds. Try it and see.
Crossing Left and Right Speakers
Someone in, I believe Audiogon, recommended the Audio Analyst and I checked him out.
He stated that crossing left and right speaker can affect soundstage. How can that be? wouldn't it just reverse the left and right sides of the soundstage?
How could it do anything more?
Curious,
