Though it's possible that a given manufacturer may mistakenly wire the terminals incorrectly, It is common practice that "red is positive and black is negative." I think you can, pretty much, count on that being the case with today's speakers.

Where is this test? What is it called? I didn't find anything on the SW3 DVDs that sounded likely. I've got to find where my son "hid" the others to see if I can find anything on them....

If the disc has the THX Optimizer, it usually can be found by going to the disc's main menu, and looking under "setup," or "languages," or some similar setting.

I guess the question is "what does positive mean in the context of a speaker ?". Cones go out ? Cones go in ?

In reply to:

The cone moves out with "positive" voltage and in with "negative" voltage on any correctly wired speaker.
Just tested this to make sure my recollection is correct... with an Axiom 4.5" driver, a small paper cone full-range driver salvaged from a "boom box" and a speaker salvaged from a set of Altec-Lansing 2.1 computer speakers.

Thanks for the advice. I found a THX optimiser on Pirates of the Carribean, believe it or not. Running it, I actually found one of my speakers out of phase... (How embarassing!) That movie sounds awesome in DTS-ES!! You're right about the sound imaging, too. Thanks again!

Hey, that's why the tests are there. Glad you found it.
Did you notice a difference after fixing the phase ?

Yeah, I found a difference. Before running the THX optimizer, I ran the speaker noise tester on the receiver, and found that my surrounds were reversed. So that made a big difference in correcting the fuzzy location of fly-by sounds. Then, the phase correction kind of sharpened the focus.
