What is the purpose of having the flexibility to re-configure from straight to J horn? This thing will be large and massive enough that physically moving it from one configuration to another will be difficult and require a lot of effort.  Conceptually it would be interesting to compare each configuration and learn about sound.  Nothing wrong with the idea, but due to its size and weight, is their any real-world application?  I don't think so... I like the other poster's idea of a configurable throat, compression ratio, and back chamber.  Sure it has drawbacks too, but you could learn about the affect of different compression ratios and throat sizes on your driver's behavior.  You also gain more flexibility in case you want to use different drivers.  If you want the ability to modify and control the sound from this horn and driver, why not focus your efforts on the throat-side instead of the mouth?

I think you took it wrong. No one plan to “physically moving it from one configuration to another” and there is absolutely no my desire to have any “learning” experiments with it. If I will do it then it will be done once and right - I will know what I will do. The purpose of having the flexibility to re-configure from straight to J-horn is to have the opportunity do not redo the whole horn is you ever need to go from straight to J-horn or vice versa. To make another mid section is not expansive and complex but it would be possible ONLY if the horn is cut on the sections with the aim that it might be re-configurerable. The horn will be made with sections anyhow – so the slicing the horn on sections might be planed considering a future re-configuration.

Let me die you another scenario. You made the inverted J-horn with enter height of your room.  Instead of hanging it you attach to the mouth two legs on skates (all the way to floor) and not you have a tripod upon which the horn stay: back chamber and two legs. Now you can move your horns as the room looking for the right position using my ideas of the macro-imbedding. After you found the right position for the horns you can hang them there from ceiling but you suddenly discover that in those found positions you do have room to continue the neck of the horn as a straight horn.  In the horn is made with re-configurerable aim then you will mark the found position of mouth, flip the re-configurerable middle sections on the horns (or only on one of them) and then you hand to ceiling completely straight horns . It shall free up a lot of footprint in room and make the horns “invisible”.

Sure it I fill the hors with helium then they might float in the room themselves and I can shepherd them like a flock of geese…
