Mesa Cab Help

[Tigger Bangdang]

Hey guys,
I have a Mesa PowerHouse 4x10. One of the speakers was replaced with an ome Mesa speaker about a year ago. Since then everything has been cool. Now I have realized that the cab sounds "weak" and I have now noticed that one of the speakers is out of phase. It is moving in while the others move out. The speaker doesn't sound blown, but it definitely isn't right. Any thoughts?

The guy that fitted it is an idiot?

Take the terminals off that speaker and swap them over.

I'm the guy that fitted it... It isn't the same speaker. I should have clarified that.

Ok, best you can do is swap terminals over so it's moving in the same direction from now on.

Ideally, replace it with a matching one, but since you didn't notice it was too off with the wrong one miswired there probably won't be a lot of milage in that for you.

Thanks. The weird thing is this just started. Can a speaker go out of phase before it blows? I need to just take it out and put a meter on the terminals and check the continuity.

 

[Downunderwonder]

That's weird then. Really hinky weird. I think you probably only just noticed, but by all means check out inside.

Afaik the wire starts at one terminal, goes to the coil, comes off the coil, and back to the other terminal. No way for it to switch polarity.

Or possibility #2 it's blown again which would cause it to pull in while the speakers working to push out are doing so. If it's toasted it would act like a passive radiator and would move in the opposite direction of the other drivers. Also causing lower volume…

Glad someone's awake!
