It's a type of speaker that is more and more in fashion with the more "hipster youth with money" who don't want the mainstream stuff. They like the styling, and if the sound is not too bad, they think it's hifi. We got a bunch of hipster "listening bars" popping up in Europe, modelledd to the Japanese original, and they all use older Kiplish or Altec speaker setups mostly. Big woofers and big horns for the tweeter are what they want, and off course vinyl and tube amps. Music is mostly (modern) jazz, funk, soul, afrobeat or the "better electronic music"
I got also a lot of demands to design custom speakers like that (i did build a few) and i like that sound also. But i don't do old drivers mostly, i use modern high engineered pro drivers (B&C, BMS, Faital, Beyma, 18Sound, ...) and a well studied cabinet, and do only the design in most cases, the build is done by pro carpenters and the electronics also by people who knows. And those builds are also very expensive (5-25K depending on what and how) for a set.
But i don't claim superior sound, i tell them the sound will be coloured and how it will be and that the usual suspects of ASR are much cleaner in sound. I also always suggest dsp for crossover, but 90% insist that i design a passive crossover for it (that is also expensive to do right) so they can driver them with their vintage amps or tube amps. These people don't trust the "high end" industry and rather pay someone like me (i'm certainly not the only one who does it) to do a custom build. I'll be cheaper, better sounding and more exclusive than a Wilson or so... even if i'm not the best designer in the world (far from, but i know something). And it's not cheap to hire me or guy's doing similar thnigs down here. They know the snake oil stuff, but are still not in the ASR camp neighter as they still judge with their ears only. I always do and show measurements, but they don't care much about them.
Some brands also do small runs of a standard model, or build it to order. I don't have a production facility and it's a hobby, my (main) job is IT, not sound so my time is very limited. Ojas does something similar at the end, but way more organised and hyped, and he just copy old designs, I and the other guys I refer to make new, and don't hype ourselves. We got refered to. I did not intent to do this, speaker building was and still is my hobby, and some heared my stuff. So my designs that are build are very small in numbers (last year 5, of which only 4 were paying, one was an own project (for a close friend). This is because i want to keep it a hobby and still have time for my own projects.
But these type of speakers are certainly a hype among a small part of the youth, and it's a financial strong one. And Ojas knows that.
