well don't laugh but its a Paradigm Monitor 8 .. Been meaning to upgrade it but been other things first.. Its not bad though is why I keep putting it on the back burner.. Applied the PBK to it.. I checked the specs after I read your 1st post and can't find the impedance anywhere - manual, online, Paradigm website..
BAT makes transformer coupled output with both XLR and single ended.. But after the "false" claims BAT posted on its impedance I think need to look elsewhere..
I think the MP-3 its going to be and find a sub with XLR input
