Carvin Legacy 4x12: one speaker isn't working (help!?)

[Executioner213]

After almost a year of little-to-zero use, I have started using my full stack again. Now that I fired it up, I realized that my angled (top) 4x12 is only producing sound from the bottom 2 speakers and the top right one. Top left is dead. I opened it up to see if there was a cable that came undone from the various moving/traveling for gigs/etc...everything was intact. Anyone have any insight on this. I don't want it to be putting different use on 3 speakers for too long, and the only other option I can really think of at this point is to order a new input jack plate in case the current one is shot. Suggestions?

Put a 9V battery against the speaker terminals.
If the speaker moves - it's a cable issue, if the speaker doesn't move.. you have a dead speaker.

Nice tip. I will try that tomorrow. Thanks.

Did the speaker test in the video above on Friday and found that the speaker is fucked. It made pops when I touched the 9v to the lugs, but the cone didn't move. I tried it on another speaker just to be sure I was doing it right, and that cone moved. Got to get another Vintage 30. Kinda sucks, but at least I know what the problem is. Still confused how that even happened. Oh well. Thanks again for the tip.
