DDT is limiting, damn good limiting at that. Beats the fuck out of Crown's ODEP... that's horrible shit.
I'm still rocking some older SP2XT's and Impulse200's, and have a few CS800x's in storage.
Back on topic: I like how MarkZ recapped this - that should clear up anyone's misunderstandings about clipping and RMS power IMO.
And his "[the caveat here is when tweeters are on passive crossovers... then it's a different story]" statement is spot on wrt my previous comments on how/why clipping can kill tweets more easily than a woofer (in a passive full-range system).
