I have been working on my system. I post sparse as I need to listen a lot before doing any changes or decide on anything.
I have changed the 1000hz JMLC horn to a 1400hz JMLC horn and the results are better. I have better integration with the Fostex t500amkII and the crossover point of the fostex t500amkII's are now a little higher. This means better efficiency and less reflections from the top of the upperbass horn for me.
I have also been working on crossovers and it seems when you have 6db filters, for them to be effectively working the impedance response should be as flat as possible. Then they work accordingly. So the simple 6db filter is not so simple at all. Now I understood why these Vandersteen crossovers look like they do!
My channels are now working in between these frequencies effectively;
Dual TAD 1601b bass reflex boxes: 34hz to 150hz
Supravox 285 in 110hz tractrix: 150hz to 500hz
Radian 850 in 200hz tractrix: 500hz to 4500hz
Radian 475be in 1400hz JMLC: 4500hz to 9000hz
Fostex t500amkII: 9000hz to as much as they can play up to 
I had been demolishing walls etc, so there is a lot of dust around and the horns look filthy. I will be posting beau photos in the coming month, with the whole system.
