The Fs resonance does have its width BUT that means that the 30 Hz PR resonance out of my example is excited when the driver is not exactly at 30 Hz (not that a 30Hz PR can resonate at 32 0r 28Hz!). By definition a Helmholtz Resonator has one frequency based on mass and the air spring. If we want multiple frequencies, we need multiple PRs that each have their own frequencies (and due to "Q" their own trash when other frequencies are needed). In addition, the PR needs several cycles to "get up to speed". It is ALWAYS way behind the active driver.
The problem here is the single PR RESONANT FREQUENCY that will modulate everything else.

Basically all important resonating structures in audio look like hell from both frequency and time domain perspectives.

All of this technical stuff does not necessarily correlate to good or bad sound. Plenty of audiophiles are very tolerant of things that their friends have not yet criticized...

I have 2-3 audio friends and never listen withe them if that matters.

@Paul - I got what your are saying about the 90/70dB setting. I do miss however some headroom for big orchestras as I have mentioned.  I'd love to know how many active SS would be enough. My space is a strange shape (living room semi separated from a kitchen and connected to a small entrance space). I do not have much space for the subs, would be great if by some luck 1Active+1Passive per channel would do (I listen close distance at 2.4m)
