Morning,
I'm not disputing what you heard, but your conclusion that the LF must modulate the tweeter section can't possibly be right. 0.047uF is a -3db rolloff of 34Hz. If you're saying that over 0.68uF was fine, then by implication 0.47uF is not as good, that means that a cutoffs of 2.3 vs 3.4Hz on the tweeter channel make a difference!

Hence I'm thinking that LF modulation has nothing to do with it.

I think it has to be something else, to me it now sounds like the impedance issue is the most likely. Roughly 1k Zout with the 0.047uF; then again, given that the driver will have a Zout of at least that, can the 6c33 it be that sensitive? Maybe... who knows?

Anyway, you seem happy with it now, so I guess the case is closed and unsolved.

cheers
