Default Help with Avance dana 660 center crossower

I am in deep trouble
I bought the dana 660 center speaker and the sound was OK, but of course I had to look at the filter I decided to build a new one with better components but something was lost in translation.

The diagram in the link above shows a drawing from the PCB board from the original filter, but I must has missed something because the speaker sounds like sh.. now.

I can here you say, look at the pcb board again right!! but I throw it away

Can anyone help do a review of the diagram.

Suspect that 1.5uF which is in parallel with resistor are in wrong place.

It is typical values foe zobel, put them 1.5uf+R (sequentally) in parallel to tweerer.
