Is there a visual way of identifying the positive and negative terminals on the speaker or does it not matter?
I searched and I'm getting mixed messages:
The wiki seems to think it's important that you get the correct polarity:

Whereas this poster thinks it doesn't matter because the speakers are so small that the difference in sound quality is not noticeable.

Any help is appreciated.

I'm faced with this exact question too. I can't believe it's not been answered yet!?

Surely it's documented somewhere? I took my speaker out of an old gb and all the circuit board says is SP1 and SP2?
Can anyone help?

With a single speaker system it doesn't matter only matters with stereo.

it doesn't (usually) matter - those speakers are essentially a resistor, so you just feed the current through it, either way, and it makes it vibrate. swapping the wires might cause the sound to change slightly, since i think it would probably flip the soundwave, but it's not something you'd really notice.
(when you have stereo speakers, then it can matter, since if one soundwave is "upside" and the other speaker's is "downside" (or "inverted" or whatever you want to call that) then you have a situation where one speaker may be basically cancelling out the wave of the other)
