Speaking of speakers, so to speak...
Consumers Union (publisher of Consumer Reports) lost a major case in the U.S. Supreme Court when sued by Bose. The speaker manufacturer didn't care for the review and showed CR to be full of shirt.
In case no one is interested....
Actually, Consumer Union won by 6-3 at the US Supreme Court:
"Bose Corp. v. Consumers Union of United States, Inc., 466 U.S. 485 (1984), was a product disparagement case ultimately decided by the Supreme Court of the United States. The Court found, on a 6-3 vote, in favor of Consumers Union, the publisher of Consumer Reports magazine, ruling that proof of "actual malice" was necessary in product disparagement cases raising First Amendment issues, as set out by the case of New York Times Co. v. Sullivan. The Court ruled that the First Circuit Court of Appeals had correctly concluded that Bose had not presented proof of actual malice."
