What is new technology in speakers these days? I don't know of any major driver type that wasn't around since the 1970's or much earlier. Even something "exotic" like a plasma tweeter was something invented in the 1930's. The only more recent development is DSP applied to room analysis and speaker equalization/control, and the most innovative example of that is the B&O speaker that utilizes multiple drivers and wave cancellation based on DSP analysis of the room to control the dispersion pattern of its drivers. It, by the way, costs way more than $30k.
The bottom line is performance as compared to peers. It has nothing to do with technology employed or the cost of components and manufacture. If someone can use cheap parts and build something great sounding, more power to them (and profit) and one would be a fool to get something that sounds less satisfactory just because of an analysis of cost of manufacture.
I have not heard the speaker so I cannot comment on its sound, much less its worth. How many criticizing it here have actually heard it in a reasonable setup?
