Some questions about bass integration and XOs (Oris Horns)

Hallo Rooze!
Another aspect to the problems You mention, is following: Even if You would use a very steep x-over - lets say a 1000dB slope, even than, the bass system would produce some harmonics, which could be, depending on several facts, well be in the midrange, beiGCg only 20dB lower than the Signal from the midrange-units.
So the first question is, how many Harmonics produces Your bass-system ( simply switch off the amp for Your Lowthers and You´ll hear!)
Next question is, what does an active x-over to Your pulse response! You should look at the output of the x-over with a scope and feed the input with a square-wave. I´m sure, with room-correction and all that, there´s not much left of the squae-shape!
I myself use a passive x-over with quite good results.
Of course I read also the other postings - the facts mentioned there, are of course also relevant, erspecially the phase-situation.
Best regards
Stephan
