I agree. From what I see they are an H series. I'm probably going to hold on to them and to continue to research them.
Here is a label that I found that is most likely what they are. They listed the numbers on the horn and the tweeters and such that match mine. I have to tell you all, I'm thrilled to death to finally have a pair of these. I had very well to do friends in Billings Montana that had Klipsch throughout the entire house. I always wanted a pair.
