The SW100 and the HP1030 are not in the same class, not even remotely IMO.
Though I need to admit, that I never had the HP1030 on my work bench.
Just look at VC winding depth versus gap height and Xdamage.
In the beginning you talked about no compromise subs, for that the contenders are: Faital 18XL1600, the SWs from B&C and Eighteensound NLW9000, the 9601 might be an overkill.
The colourfull pictures Ive seen here are just that, nothing more.
Without LEAP 5 and some high power impedance measurements of the drivers in question you cannot simulate what happens, if you drive them hard
