You said " When the Magnepan IIIa drivers were being used did you measure the SPL of the driver directly ?"
No, I didn't ... I simply modelled the passive XO and then applied similar filters in my active XO.
" I'm wondering if there is a bit of a hole in the output at the crossover frequencies, caused by the 'tuning' of the panel. Seems like it would be very difficult if not impossible to tune the panel so there is no loss of sound output near the (mechanical) crossover point ."
There may well be such a 'hole' - but if there is ... my belief is that this would be caused by the XO. So no 'tuning' of the panel is required - simply an adjustment of the XO component values to bring the LP & HP 'roll-off points':
* closer together if there's a 'hole' at the XO frequ
* or further apart, if there's a 'bump' at the XO frequ.
An REW sweep should tell you whether any 'XO holes' exist.
