I signed up to receive a couple of newsletters and one came today from "This Old House".

In the discussion of home theatre speakers, the writer claims that it takes more power to drive low resistance speakers than it does a higher resistance. This is completely backwards and wrong.

Ohms are a measure of resistance. Higher ohm rating means a circuit has more resistance (not less). For instance, 8 ohm speakers take more power to drive than say, a 4 ohm speaker. The writer claims just the opposite.
