What is the maximum distance allowed to the golden-seat to be considered near-field... 3ft from ear XYZ 3D-axis or just 2d distance?
I would imagine that that would exclude a lot of people that have multi-rows and/or if their golden seat isn't in the back-row with a sub eating their face (unless they have a VOG IB sub hanging from their ceiling that "somehow" doesn't interfere with their projector beam... LOL!)
I only have one row (at the moment) but my extreme left and right seats each have a sealed 21" sub that is within 4ft on the width-axis, but that's 7ft from the golden seat so I guess it would be excluded. Two of my UM-15's are within 7ft of the golden seat too.
In theory those guest seats would have slightly more bass than the golden seat does... how strange!
If we are taking distance into consideration, I have 20 subs all within 15ft of ANY seat, with the average distance being 10ft to 10 subs from ANY seat, so the "density" is fairly HIGH when you look at it from a distance perspective.
You mean you didn't spend $40K commercially on all your subs?
Will fix it on the next update!
Regarding the distance...hmmm, I guess I'd have to say 4ft max.
You make a good point for folks with nice big fancy HT rooms. Aesthetics put a damper on optimal shakability unless you go ellis way and do the DTS10 as the riser. I went with the Golden Seat because I'm most interested in what that experience is like as opposed to the other seats. When I think about the ULF score, I imagine walking into your HT Room, you directing me where the best seat is, me sitting down, and then going through the barrage of demos to experience your ULF.
It's the tradeoff...some sacrifice the money seat to have a more even response/experience across all seats. Other sacrifice the other seats, to dial in the best experience possible. Some are lucky enough to have it all!

If my memory is correct, MK and N8 have fairly high densities too...
I think you should collect the average distance ("density") from all member's systems, and come up with a way to try to use that in calculating a "real-world" in-room SPL score, based on room volume and average distance to LP. Might be interesting to compare the theoretical-groundplane score to something more approximating a real-world type score.
There might even be an approximate correlation pattern between groundplane and such a real-world score I'd wager.
-6db for every doubling of distance, plus some sort of pressure vessel curve added etc; whatever algorithm is best.
I've thought about this too...I'm sure there is a more scientific way to go about this, but that would require collecting a lot more data and I wanted to keep this simple. For those that are that serious about really wanting to know, there's no replacement for good measuring gear (like yourself!)!
