Thanks for this. Very interesting. I recognised the hardware drawing instantly.
I used a variant on an amp some years ago for splitting out sub-bass, just
using the high and low pass outputs. It made tuning to suit the actual speakers
It wasn't me! (Well actually, it probably was)
... the hard part is not dodging what life throws at you,
but trying to catch the good bits.
