I've never heard that term used before. I have to say, though, that if it's marketspeak, it probably refers to the meaningless "peak" number.

I never purchase a piece of equipment unless I can see the RMS specs. That's one reason I buy from Crutchfield-- they always list the RMS numbers. It a lot of fun to see a photo of an amplifer in their catalog with a huge neon-lit "400 Watts" on top, and then see them rate it at 80Wx2.
