I'm not so sure the history of it's rating. But I thought it had always been rated up to 1000watts continuous.
They are pretty fragile cones. Made out of aluminum. If the owner doesn't know what he's doing then he can damage it fairly easily. I think one of my nieces tried pushing on the cone and left the tiniest indention. I still put it in and after I ran some power to it the cone is fine now. Matter of fact it may have pushed that blemish out?
They're designed to use low air space and they play flat up to 1khz. Ideal is about .5 cubic w/300-500watts I believe?
The horns don't act like tweeters from my understanding. Since it's based on compression you don't need to use them at ear level yet you still maintain a high sound stage. Wave guides are pretty interesting. Patrick Bateman is a big fan of those on DIYMA.
