I’m sure the Borresens sound great but the whole R&D and advancements notion is mostly false. The marketing people would like us consumers to believe that’s the case but in reality there exist 30+ year old speaker models that would compete with nearly any speaker in the X3’s price range. Speaker tech has long been more mature than most audiophiles realize. The difference these days is the number of different models that compete at the top echelon, and some at a relatively lower price when adjusting for inflation.
It’s not unlike how tech has progressed in cars. For example, self-parking cars have actually been around since 2003, but they didn’t become relatively common until a couple years ago. Similarly, ultra high fidelity drivers have existed for decades, it’s only that these days they are easier and cheaper to manufacture.
