I just installed some expensive in-wall speakers, and they sound out-of-phase to me, though it is hard to tell. The wiring is done correctly, and I've checked the components for proper output modes. But, the sound is hollow and thin. (Please note that these are for stereo sound, so surround is not an issue.)

Is there a disc (CD or DVD) test for this? I can't remove the speakers and have them face each other, which is the normal test. Does anyone have a sure-fire test?

Thanks in advance!

Some DVD's have a mini THX testing for both video and audio. I'm pretty sure it has an out of phase test. Check out "The Incredibles" DVD, I'm pretty sure it has it.

Thank you for all the feedback. I don't expect in-wall speakers to sound as good as standalone, but I wanted better sound than I'm getting.

Again, thanks!

Well they can depending on they brand and how they are installed.
