    What model speaker is it?

    I know some of the Polk center channels had a passive radiator in them, which would cause one of them to be louder than the other, simply by it's design. I'm guessing that's the case.

    No passive radiator there. Possibly a disconnected wire?

    Hm...I don't believe that model has a passive radiator. It does, however, have a cascade tapered array. What that means is that the two 6.5" drivers are tuned to different frequencies. One driver is crossed at a lower frequency and is essentially a bass driver. The other driver plays the upper midrange frequencies, which eliminates interference between the two drivers.

    This could be contributing to the different volumes between the two drivers.

    One thing you might try is removing each of the drivers, and connecting them one at a time directly to the speaker outs of your receiver. Play them at a very low volume for a few seconds. If each of them appears to be at the same volume...then neither one should be blown.

    Best way to figure out if it's blown? Listen to it. Does dialogue sound distorted or lacking when watching a movie? If you're just comparing right vs. left speaker output, then that's not enough......
