but it is technology, isn’ it? like computer, right? no?
Physics are a huge part of speaker design and function, and that has not evolved.
The technology has evolved, but there haven’t been many "breakthrough" advancements that changed the game dramatically. It’s more like many marketable baby steps. Emphasis on "marketable", because in many cases, sales and profit trump sound improvement. The majority of speakers are profit boxes that typically don’t represent state of the art from their era.
I’d be surprised if there weren’t several great speakers from the 60’s and 70s that wouldn’t raise an eyebrow or two (assuming any age-related degradation was addressed)
