Simp,

Yes, I did leave my question wide open so as not to limit the categories when people replied.

What I didn't expect was that people would compare a THX item from one category (computer speakers) to non-THX gear from another category (home theatre) when the certifications for each category is very different.

That's about as fair as saying THX speakers have crappy bass response but neglecting to mention that the 80Hz roll-off is a specific design element and not a limitation of the speaker manufacturer's capabilities.

Mention of THX seems to bring out strong emotions in people, not just at The Saloon but on practically every A/V forum, and I have yet to figure out why. I can understand why double blind testing would upset certain people; but a certification process? Like I said, I'm really curious about the claims of crap products being able to get the THX badge.
