Thank you for your response. I do find myself in a better position to optimize. Last thing is damping inside the chamber. Are there good rules of thumb on this, just like with volume tuning?

thank you. Gera

...if you had a lot of room for damping material in that backchamber.  In a regular sealed box speaker damping material is often used to present to the driver a larger apparent cabinet size (so you can make a smaller box) and to a lesser extent to lose a little of that energy through friction.  In this case you need to find the right internal volume and not necessarily reduce its external dimensions.  Also, horn backchambers tend to be quite low volume and combined with the dust/residue/crud issue with the magnetic gap of the driver I doubt you could get any positive long-term result by using damping material.  Do not let me dissuade you though, I am just giving a general opinion and not necessarily one pertinent to your horns.
