Stereophile test CD2 In/Out of Phase test:question


Hi
I just noticed that on Stereophile Test CD2,on the second track that shows in-phase and out of phase recording ,if you switch speaker wires on the amp end you will still get the test play thru your speakers as if you had a non-inverted phase.The test sounds identical not depending if you changed phase of your system or not.Please,explain why this is happening?

JBL are not the only ones!
I quote from the owqners manual of my Tannoy Little Red Monitor:
"Absolute Polarity
The convention on all Tannoy loudspeakers is as follows:
A positive going signal (ie =ve terminal of 1.5 volt cell) connected to the positive input terminals of the loudspeaker cause LF cone to move into cabinet. In this way, the absolute polarity of the signal from microphone to loudspeaker may be preserved."

Funny that it is JBL and Tannoy, two companies who have probably done more fundamental research into acoustics than all the others combined, would wire their speakers that way.
