I've got so many great replies on my questions, that perhaps my main remaining question will be lost, so I hope you don't mind that I put it forward again and at the same time I have tried to isolate the most important question and also tried to clarify my question/problem.
A few days ago I received a suggestion on a first order x-over from an expert, which he said, would work and at the same time flaten out the frequency response on the 2445J driver
So, I'm asking for your help on this somewhat unorthodox x-over.
Will it work and will it reduce the hump and even out the frequency response between mid and high on the 2445J?
