I think my center channel may be blown. I have a yamaha ns-ac40x running off of a yamaha rx-v1400. When I turn it on the speaker sounds very hollow and you can barely hear it. And when I turn it up to about -10db the receiver shuts off and says "check speaker wires." So I thought it was the receiver. But when I hook up my old pioneer center speaker which is much weaker and smaller I can turn the volume a lot higher and the receiver does not shut off.

Is my center speaker blown?

Thanks in advance for any replies.
