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.)


use a Light Emitting Diode LED play music at low level, while
placing led over connections, LED can only light up at one way
connection position....


That makes the rash (especially with cheap speakers) assumption that the
speaker connections are hooked up to the internals the same way in both
cases. Much safer to actually test the sound output (or, as someone
said, to see which way the cone moves with a DC source).
