Biamp v triamp: I was planning only to biamp but did the model for triamp just for completeness -- the mid LP and treble HP filters could be ignored for biamping and the speaker level crossover for the high end left intact. Interestingly the translation from the parallel speaker level crossover to the ALLXO requires 2nd order filters not 1st order. There seems to be a problem with my installed version of Librecalc so at this time I cannot pull up the spreadsheet and Bode diagrams. IIRC I could flatten the hump but then there was too much deviation from the OEM which is not what I wanted. I am of the opinion that the active XO should closely emulate the OEM so the voicing is unchanged from the manufacturers goal.
