B&W 801 Series 80 Bi-amping

That looks good the me..:-)

What about the negative imhififan? Cut the negative right next to the positive red X and put the wire to the (added 2nd) negative binding post?

@oldhvymec , thanks! I forget to mention the negative binding post, it need to cut the trace on PCB to separate LF negative from MF and HF negative connection.

Ok, so this looks like an internal wiring job. Thanks for confirming this is way beyond anything I’m willing to attempt. Single channel it is.

I found the schematic on the net, It is a parallel xover design, you can disconnect the 6.5mH coil from the input (marked X in red) and wire it to the positive side of a new set of blinding posts, that will be the LF input for bi-amp and the existing blinding posts will used for HF and MF input.
