(I'm still very fresh to crossover design)
I have this Jamo crossover (ripped out of a Jamo Art speaker) and I'm really confused at why it appears that the network is entered via the negative input? 🤔
I've mapped it out and it appears that if I hook it up, the filters wouldn't sit in front of the drivers.
I'd really appreciate if someone could let me know what is happening here.
Should it be inverted when connected to an amplifier?

The usual polarity convention for loudspeakers is positive voltage applied to the "+" terminal drives the cone forward, away from the magnet structure.
The raw Jamo speakers I purchased were wired as black for "+", white for "-", opposite from the usual convention, easily checked with a battery.
Out of 120 speakers, two were wired with reverse polarity from the others...
If your Jamo speakers are wired the same as the ones I checked, the crossover inversion may bring them back to the usual convention.
