General passive-line level filtering issues. (BD-Design)

Hallo Bert!
I know that You use the filter at the speaker terminals of the main amp, to keep the general characteristic of that dominant amp.
I went a different way: As main amp I use a SET-amp. The biggest amplitude is in the bass - so if there occurs clipping it will happen there first and produce harmonics. So I filter the main-amp at the input, that it has to produce no bass.
That means I´ve to split the line signal before the main amp, which I do with a passive network, like the one published in the forum.
For my system, that works very well. The network was tuned to the drivers in use, so slightly different to Your Oris set-up. To get symmetrical responses I used a 18 dB filter..
Maybe a path worth a try for You?
Best regards
Stephan
