I assume they just never unboxed it based off the junk they put out.
If you already built your chamber on company grounds years ago you use that
Allegedly the klippel system is atleast just as good and possibly better than the smaller chambers ? And then it’s not expensive at all compared to a very big empty building filled with sound deadening contraptions .
So I get the appeal you can do it automated in a spare room or ( or garage or shed if your a one person business

)
I can share a little regarding these topics as an industry insider, but I won't go too deep.
B&W put a lot of resources into research, if I remember correctly, at their new office in Southwater they have like 3 or 4 anechoic chambers, and I believe they have Klippel equipment for driver measurements like most of the big brands. And from available data, you can tell their drivers are actually pretty good. B&W has a big R&D team but every engineer only deals with one type of thing, and there is a small team of people who decide what the final tuning/response should be. Based on the outcome, you can tell It's just that they don't agree with the Harman group / Dr. Floyd Toole's philosophy in terms of loudspeaker system design, it is probably more about some business decisions, the sound signature they want to maintain etc, and it has worked for them, for many years, so I don't see why they would change it dramatically even they can easily do. (Quite a few B&W engineers are ex-KEF engineers and I got contacted by the B&W recruitment team twice as well so I know a bit about them...)
In my opinion, a Klippel NFS has a lot of advantages over the traditional anechoic chambers (especially the small ones), but one also has to be careful about it as errors can happen due to measurement setup mistakes. The practical problem with anechoic chambers is that, usually, they are not big enough. You will run into the chamber cut-off / remaining room modes and you still have to find some other way to measure the real LF response / polar of the speaker and merge it with the chamber data. Many small chambers have issues starting from 2-300 hz, and depending on the size of the speaker that can be where the baffle step response starts. Near-field measurement is not the best solution here as it can't capture the baffle step. Another problem one often encounters is that, for a big floor stander with multiple woofers, you can't get the true far-field response by measuring it at 1m in a small chamber. For all these issues you usually need a huge space or go outdoors to sort things out.
And if you wanna measurement the polar response of a driver, or design an in-wall speaker system, you either build a 2pi anechoic chamber (rare to see, usually owned by driver OEM company, Tymphany UK has the biggest one in Europe, and it is impressive) or you find a big open space and dig a hole for the speaker on the ground to do the measurement. For the latter one, I have good memories of trying to save the speaker and all the measurement equipment with my comrades under a sudden rain (UK ain't it).
The NFS, if used carefully, can deal with all the issues above and make one's life a lot easier, and a lot cheaper than building a big anechoic chamber.
