CD Spkr Set-Up ?

XLO Test CD, the out of phase track for speaker set up. Accept no substitutes.

Can you guys go into a little detail on how you use the CD to set up speakers?
TIA

For the XLO Test CD speaker set up track, you are instructed to move the speakers around a little at a time while the OUT OF PHASE track is playing on repeat until the sound is coming at you from all around the room, in other words there is no directionality at all to the sound. Then when you play something that is IN PHASE you will get the best stereo reporoduction with the best soundstage.

Interesting, Geoffkait. Thanks.
Only issue is if you have big speakers...

That Isotek CD…if it's the same one as perviously mentioned…has a cool "sound goes around your head" track. I use one of the Stereophile test CDs sometimes, and that Sound Tools app for an iPhone (real time and frequency stuff). However, nothing beats simply listening to music to tweak things.
