did I blow the speaker?

I have Model 10Bs. I have a phono that occasionally builds up a hum. I have an Adcom amp w/ 250Watts/ch. This aggregation of facts appears to have conspired to wreck one of my midrange drivers, which I thought heretofore to be indestructible.
On pure tones in the upper midrange, there is a fuzziness to the sound. What can I do to isolate the failing driver, so I can then extricate and then replace it (the two are pretty close to each other)?
