AR3a restoration

Hello everyone,
I’m in the middle of an AR3a restoration and one the woofers has very faint sound but no visible exterior damage. I swear it was working. Is there a sure fire way to tell if I’ve blown it, which I don’t think I did. I tested it with a 9 volt and it moves. The other speaker works just fine. It’s not the amplifier and I’ve replaced the caps and the pontentiometer. Any thoughts would be appreciated, thank you.
