Default Testing that speakers in phase?

Could someone remind me of the simple test involving placing 'left'
and 'right' speakers close together facing each other please? Am I
right in recalling that they are in correct 'phase' when the volume
sounds reduced/muffled? Or is it the reverse?

(I have some cable extensions to do on the speakers that came with my
new PC, and both wires are identical, so I want to be sure I get it
right.)

I'd use an electrical meter (or light bulb and battery) to work out which
wire was which.


I marked one of the two identical black wires with spots of Tippex,
about 2 cm apart. So, when cutting and inserting an extension pair, I
could be sure I preserved the original status. To my untrained ear
they sound OK, but I will get around to a more rigorous test later.

BTW, I've found that some software doesn't play the rear speakers in
this 5.1 configuration.
