AFAIK B&W 800D is used in many mastering studio's. I wonder what they will do with their high-end / pro audio segment, since it's quite different from your average home stereo (or even hi-fi) markets.
I wondered the same thing...FWIW under Samsung the pro/pro-sumer audio Harman brands (JBL in particular) have managed to keep making well-regarded products from consumer Bluetooth speakers up to live PA systems and studio monitors. On the other hand, Lexicon is a former top-shelf audio brand that has pretty much languished under Harman - they no longer employ some of the world's best audio DSP talents, and have been slow to update the highly regarded Lexicon DAW plugins for native Apple Silicon.
A few months ago I tried a new JBL receiver. It was trash (the worst I have tried and I tried 5 or 6 different ones for my room). I also saw their soundbar and their vintage speakers. I wouldn’t agree that JBL makes quality products, but that is just my experience.
