He did the Nautilus as well...
.Maybe?
"4. Optimized Front and Rear Wave Alignment: The patent pending acoustic enclosure design ensures that the front and rear sound waves propagate in the same direction, with minimal phase difference across the entire mid-frequency range (300–1700Hz). This prevents destructive interference and maintains high sound quality, ensuring more consistent sound propagation across a broad frequency spectrum."
I like oak.

Interesting video by B&W on the design and development of the Nautilus
Maybe?

Yes, oak is nicer.
The design is straightforward and simple, and it is aptly named Challenger because of that. The Lithuanian engineer has rediscovered an older concept and developed it, leading to a very interesting result. A long time ago, German radio manufacturers employed that idea. And it's nice to see it being utilised once more.
However, with that sort of pricing, its sales are unlikely to go very far, as people would prefer to spend that money on a good car, which would typically come with a high-quality speaker set. I've read about the idea behind it, not from internet reviewers, but from the engineer's own writings (cross section). His other smaller speaker, Bloom, utilises an earlier patent, which is active and not originally his, albeit somewhat modified, effectively encroaching upon it.

Lovely!
IME only NXT does, and it has other shortcomings which stopped it being a successful choice.All that the designer demonstrated is that they do not know how to achieve good sound from a single speaker (driver).
The BMR, which was a spin-off of the NXT research, is comfortably the best but is best used with a bass driver too to avoid intermodulation and is very expensive to make or used as a mid driver, avoiding the expensive (consistent top octaves) part of the engineering.
I have been interested by full range drivers since the 1960s, the first speaker I built used a Wharfedale 8" RS/DD full range driver, my aunt had a Lowther Acousta.
The problem has always bewern the laws of dynamics which, until the NXT and BMR research, meant all the drivers inevitably have a very uneven frequency response.
Their biggest attraction in the HiFi market IMO is they are eccentric and most are very expensive, or have some sort of marketing narrative hype attached to them which appeals to some people.
Wizzer cones resonate or aren't stiff enough, modal types like the Jordan and its offspring are interesting. Only the BMR actually works, so far, and then is not best used full range - because physics
BMR is made by the same people, who worked in NXT in 90s, now living in the US. At least one person is still there at Tectonic Audio Labs, Tim Whitwell. That Ukrainian Oleh Lizohoub is using that BMR idea together with the NXT bending waves idea. It's great that people are still experimenting rather than simply resorting to carpentry.

Not sure that post required your level of vitriol in reply . Let's be more respectful of others views please .Your childish disgust of all loudspeaker designs different from dipole/open baffle is almost funny ("precious back wave").
That was current when I was a teenager and motor sports fan.
We called it the "Slumber Super Sleep"
Getting fully modal radiation rather than a range of strong peaks is mainly a production problem.
It requires a very precise amount of assymetry to excite as many modes as possible and a symmetrical speaker will always excite a few modes very strongly and give a peaky response.
There are other difficulties too - mathematically the BMR is brilliant but the manufacturing tolerances required to make them work as calculated and all the same requires levels of precision no mass production driver maker is used to working with, as I understand it.
I was a consultant to Lola Cars for a while and whilst I was in Huntingdon working on the Indy and Le Mans cars I stayed in the same place as the consultant engineer doing most of the modelling and prototyping of NXT then BMR so my info is from the theoretical side and hearing prototypes over 20 years ago. I have some NXT cardboard demo speakers still somewhere, they sound surprisingly better than anybody expects.

OK, I apologize and I will not comment anything further coming from member Lekha. But I have to point out that member Lekha actually is mocking all designers and users of non-dipole/open baffle loudspeakers.
I suppose, Dr. Graham Bank was the initiator of BMR technology. Have you met him?
The list of products they have been involved with is impressive.

I don't know who actually came up with the idea in that team. I have met Graham Bank, a legend in the business, yes.
IME the saying "success has a thousand fathers and failure is a bastard" is often the case in business and sport.
He is the man behind all those ideas, such as bending waves and BMRs. Truly one of a kind! I believe he is now retired and has stepped away from the spotlight. You are fortunate to have had the opportunity to speak with him.
This last one,
i thought this was about most beautiful speakers! oh well, perhaps they are very good speakers, just paint over them side panels and you're done .The other color options and models are fine by me.
I'd love to see how abysmal the performance of these is.
Those are my old ones , I sold them and bought a pair of Ino PI60. The low end of those LTS is very impressive, in my room well below 20Hz
