I have seen articles in the past on tuning aperiodic enclosures and they always seem to focus on minimizing the impedance peak at resonance. Which I guess would also mean tuning for the lowest Q. Does this make sense ?
Yes. Althou the Q can go down with a peak at the same height but broadened at the base.

The Qtc cannot go lower than the driver's Qts for certain. The way I did it, I did not look to maximize the impedance curve's flatness, but stopped when I had the desired Qtc, 0.65-0.7 was my aim. I guess at some point, if you try to go too far and remove too much resistive material, you will start to see a bass-reflex behavior, that would be my guess.

Thanks guys. That all makes sense.
I'm learning as much as you here!
I placed the speakers better in my room and listened to some well-recorded/mastered stuff, Patricia Barber, and it sounded really good, even with no EQ (used to simulate BSC). Tried some dance music as well, David Guetta, and they did well enough; but I did hold back on the SPL to give them a chance. Looking forward to try other stuff I have on them!

That is most of the Philips. The others would be other vintage drivers i sold during my vintage driver period.

BTW, did you ever come accross any AD9710, wether in commercial or DIY boxes during this period?
