I ambled into a local audio dealer here in San Francisco the other day and
received a fairly interesting, if ambiguous, lecture.

I was told that most people don't realize just how harmful it is to speakers
to use them for watching TV or playing computer games, because both formats
use very low compression, unlike CDs or DVDs.

Is this really true? I may not have majored in electrical engineering, but
how exactly will the compression of the signal damage the speaker?
