That's frequency extremes. So the high and low ends of the frequency range are rolled off. Also wide stereo in the bass region can cause the needle to jump, so either the bass needs to be reduced in volume or made mono/as-close-to-mono as possible.

Dynamic range is less of a problem.

This problem is mentioned in the article.
