1. Is IB or EBS system well damped in the mid bass, and not so well at very low bass or "system resonance?"
IB is well damped at all frequencies, LLT is well damped until subsonic frequencies.

2. If the ringing is limited to the very low bass, will there still be slop generated from signals in the musical range?
It depends on how low you tune, how high the Q is, and how flat the resulting FR is. Here is a SVS 20-39 in 20hz tune:



Now here it is in 12hz tune:



As you can see, much less spillover into audible frequencies. Now if they designed that sub to be tuned to 12hz from the get go, meaning a larger enclosure and no high pass, that chart would be even cleaner. That's what the LLT does.

3. Where is the measured data on this?
Well I just showed you some, and you posted some yourself comparing the Monolith to the Plus/2. Unfortunately I don't have measuring equipment of that caliber nor the know how to take those kinds of measurements, otherwise I would. But it's all a simple logical progression - we can extrapolate based on the subs that are measured.
