I have a hunch. Try repeating your whole procedure using 85Hz and see if you get the same results. I believe what's happening at 60 Hz is that although the impedance of the box is at it's peak, it's most likely also in an area of maximum reactance (a polar impedance plot or oscilloscope would show us in plain sight). Therefore, the box is most likely storing all kinds of reactive power (VAR's) in addition to the real power expended and triggering the DDT. I think in this case, this is going to be your limiting factor, and you have your DCX set optimally.
As far as 8V or 10V, it would be whatever setting is just below that DDT light coming on as that's the amp's signal that you've lost appreciable headroom.
My bad, I meant 8ohm or 10ohm? Parade was great, everything worked fine at full bore. I get to do it again this sat. and Mardi gras day!
