Johan, I understand what you are saying. This is kind of James’ barn thread and if you do not mind can you share with him one thing, I think that many others, including me, would be interested to learn the answer to this question: What did you gain going for bass horn in term of Sound? You went for bass horns when you were not able to get bass in your room due to the standing wastes. It is understandable, many of us were there. However, if we pretend that you did not have problems with room modes and your sealed boxes worked as they should then would you feel that you got any advantages from your bass horns? Would you go for them if you do it again and had no room modes limitations?

Can you add a longer phase plug to your ALE1260 to let it go up 1K… I do not know I never played with this driver. Alternately you might go for ALE A7550 but it might be too bright for you… not to say too expansive juts to try… Besides theses I do not think you will find any. When I went to the same direction and was looking for my driver 100 -1000Hz (I was looking for 4” throat as I would like to have the horn of no longer then 40”) I realized that there is nothing out there ready to do. So, I realized that there is nothing constitutionally prohibitive if I use a regular drive and make it to act as a compression driver (but without the compression part). The key was to know how it might be down and to find the driver that would be perfect for the application and able to demonstrate the necessary sonic qualities. I found the driver and then John Hasquin from Indiana educated me how to use it properly. It does the 100 -1000Hz at 108dB… but as you understand it is a subject of other thread.....

I clearly hear the delays problems in Bruise Edgar 35Hz horn. BTW, I have detected that the cylindrical waves coming from line-arrays are less sensitive for time misalignment; perhaps it helps you a little. When you said that you have trued to time align and cannot hear the difference then what did you do?
