I understand
Paul,

Romy's follow on posts made it clear that he was not talking about low frequency musical notes but rather low frequency ambient noise specific to the venue. As noted above, a large proportion of this noise is extra musical and some of it is generated outside the concert hall from cars, construction or other sources of low frequency waves traveling through the ground. Yes you can sense the difference in how a large structure vibrates at low frequency compared to a small structure like the average home.

There are so many issues with reproduced sound that I have not worried about this aspect although I understand how it can impart a sense of place. But since it is extramusical it doesn't interest me that much. I do understand how it might subjectively be a pleasing adjunct to certain kinds of music. The normal reflectivity of a large concert hall and the impossibility of recreating it exactly at home bothers me more. Often I sit in the nearfield to try to mitigate that sensation, but it is omnipresent even with surround sound set ups.

Low frequency dithering
Yes I can understand that in your current room the music seems clearer to you but you prefer some slight  additional low frequency reverberation from the room to mix with the musical decay of bass notes. But this gets into the whole question of how tight or clear we want the bass to sound. Different speakers are praised or dissed depending on the taste of the reviewer for exactly this issue. Again, you have the room you have so this could get tricky to adjust only bass note decay curves without affecting everything else noticeably.

Nearfield Listening vs. Performance Weight and "Space"
I also listen nearfield in order to embed myself in the sound/music, and it's not just a matter of SPL.  I think I get what Romy is saying, but I am saying I think we have to correct reproduced sound deficiencies at/below LF if we want a "realistic" sense of time/space/scale.  Drivers/speakers have rising response, X/Os and stacking drivers notwithstanding.  Also, artifacts/noise at higher frequencies adds disproportionately to the sound we get from hi-fi.  We can certainly "listen through" or "listen past" distortion and/or omissions.  Part of the hobby for me is milking content by hearing "more" from recorded music, including some war horses that are much-loved for good reason.

Eventually!
Yesterday was a truly wonderfully day. I spent the whole day to play with playback, had a LOT of fun with it found some unexpectedly good solutions that made me very excited.  
 
The project with IB is over, the result is surprisingly good. There are some very minors things that I would like to work on but it is good enough to leave it as is. I use the horns stack + a dedicated midbass channel with Vitavox 15 driver as a direct radiator with IB sections at the bottom. I do not use the woofers tower at all. This is kind of strange configuration but it does produce a very interesting result in my view. The proper question would be how the overall sound I go got in this listening room with direct radiator midbass and Infinite Baffle might compare to the overall sound I go in my former listening room with Midbass horn and ULF section. I will be posting my commentary on this subject when I am ready to comment on it but as a preliminary view I might say that IB topology VERY positively surpassed me. 
 
Another very interesting move I made is to setup a pilot or TV playback. The projector TV playback integration with my main listening system is always a bitch. From one point of view we watch crappy movies, kids watch cartoons, Amy’s father watch his sports. I am not willing to run Milq and the rest of playback to make YouTube cartoons to sound better. From another hand we watch concerts and operas on the large screen and I would like the quality to be good. The on-demands integration did not work out well and always was a compromise, so I did an interesting move that pays off very well. 
 
Amy insisted to keep the woofer towers in the room, the woman likes how it looks. So, I decided to convert the woofer towers into the TV playback. I took a small mini monitor I build years back around the sensational Focal Utopia TN51 tweeter. It a small 2 way monitor with passive radiator that sound very respectably. I complimented it at the bottom with the whole Woofer Line Array crossed at 70Hz with first order and powered the whole thing from another Yamaha B-2. This threw a spectacular HUGE sound, exactly I needed for TV programs. The TN51 take a compression of sound like no tomorrow and I very like like hos the whole thing sound. 
 
So, I have an independent Audio and Video playbacks that happen to be in the same location and that do not talk to each other: very easy and elegant. The Video playback is a fully SS and cold running… the ultimate audio “pilot” system…
