I believe the following to be true:
The grooves on 12" singles are cut wider and deeper than on their album (or 7") counterparts. One of effect of this is to produce a deeper and fuller bass.
If so, along with the fact vinyl is analogue, does this mean that vinyl really is capable of producing deeper, fuller bass than CD/SACD ever will?
Also, many people have loved the effects of the new supertweaters even though you can't hear the frequencies it gives off. Can we get a useful effect from including sub 20Hz signals. From a theoretical standpoint i don't see why these very low frequency signals can't reinforce or otherwise affect other bass frequencies. I personally, would love a sub-bass subwoofer, even if all it did was shake my chair.

The RIAA equalisation levels the overall frequency response by increasing the bass frequencies up to their intended levels ( having ben reduced during the mastering and pressing of the LP), not boosting them beyond that point. I am sure you understand what you said it's just that it reads like you are saying the RIAA curve accounts for higher bass levels in LP based systems.
As for my 2 pence worth, yes good vinyl takes some beating in both quantity and quality of low frequency reproduction.

In theory (and practise in my opinion) CD is flat to DC and of very low distortion. Same for SACD. Neither is true for LP, although it certainly plays tunes well.

This is something a guy called Graham Holliman (I think) used to talk about. He was insistant on the benefits of 'infra-bass' to the normally accepted audible range. This kind of makes sense to me as a roll-off within the audible range brings phase shifts with it. Graham made studio monitors that were falt to 11 Hz. Island records bought some. Tim de Paravinci is a believer too.

I have been enjoying extended base from my KEF R 107 speakers for many years - spec claims 20hz to 20khz plus minus 2 db
Regardless of the marketing words, wind organ based music sounds great and all music with recorded in a large space sounds realistic.
Replacing these 14 year old machines is going to be a real problem.

There's definately something to very deep bass - witness the improvements to mid & treble quality which can be wrought via a REL subwoofer.
Can be difficult to integrate the sub-bass into the output of the speakers, though.
cheers, Martin
