[QUOTE="profundus-sanus, post: 2952884, member: 572787"] you definitely want to maintain a constant port area. You would have to calculate the tuning of the smaller area part then just guess hwo much lower it might be tuned. Since its just a step, the tuning is really calculatable, with common knowledge i'm aware of anyway. It may act somewhat like a horn tho. Just having two tuned frequency instead of a tuned range that a horn has. If it was a linear and constant change or exponential change in area then it would be a horn, but just stepping up the size from what i can conjur up would just make it a useless waveguide, that would only possibly help phasing. Simple answer, don't do it. [/QUOTE]
