Thanks for your reply and insight above.
In response - for example with my PM90 which I figure is relatively standard in using the FB464 passive crossover designed for the DCX464 :
1 amp channel supplies 2 poles +/- to the NL4 port, and then to the HB464 crossover board.
On the XO board it has 2 clips for IN +/- , the circuit of lamps, inductors and resistors and 4 output clips for MF and HF drivers respectively.
an example:
440w amp channel +/- --> XO IN +/- --> XO MF OUT +/- -->. DCX MF driver (220w)
___________________________________________ --> XO HF OUT +/- --> DCX HF driver (160w)
Looking at the crossover schematic previously posted, it appears that the two drivers in the coaxial DCX464 are in parallel so - are they 8 ohms total ?
