The center domes also known as dust caps usually get pushed in by those pushing their fingers on them. They push in easy enough. Doesn't effect their sound. But, if they were kicked in or hit hard to dent them in, there could be some damage to the woofers. I'd listen to the speakers to make sure they still sound right to make sure. Put some volume to them during testing too. I never buy any set of speakers until I listen to them. If they sound good and the price is right for you, then buy them. Chorus II are some really nice speakers. Sometimes you can pull some of the dent out with a vacuum cleaner hose.
