Could someone remind me of the simple test involving placing 'left'

right in recalling that they are in correct 'phase' when the volume
sounds reduced/muffled? Or is it the reverse?

If you've got radio on the PC check a male announcer on R4 - he should
appear to come from exactly between the speakers like there was just one
in the middle. Helps if you can switch to mono.
Or place the two speakers face to face touching one another. Change the
phase of one to incorrect. Bass should disappear.
