Tech That Flopped!


Every few months someone releases technology that seems to be revolutionary, but goes nowhere a couple of years later. Some tech gets acceptance and even imitation. Some goes wildly successful.

Ideas that are a huge success:
  • Acoustic suspension
  • Bass Reflex
  • Soft dome tweeters
Some ideas, well, it's not so clear:
  • Perfectly time aligned speakers ilke Thiel/Vandersteen
  • ESL
  • Line Arrays
  • Plasma tweeters
  • Transmission line
What tech have you seen come and go, was it worthwhile?

Best,

In related news, in science, as of today:

"Quantum theory has many strange features compared to classical theory," Richens told Phys.org. "Traditionally we study how the classical world emerges from the quantum, but we set out to reverse this reasoning to see how the classical world shapes the quantum.

........

The take-away is that all possible statements, theories and seeming rules of all objective scientific analysis all contain quantum entanglement. .... Which... means that objectivity is a fail.

That objectivity is not universal but in a localized bubble and outside of that, is, well, a pipe dream a forced projection, a non thing, in the overall analysis. A cute experiment and it can’t and does not exist. Subjectivity is illustrated by the same dominoes falling, to rule the roost in all facets.


"Objectivity is a fail" and "subjectivity will rule the roost in all facets" seem to be very objective statements. The assertion that ’everything is so complex that all interactions are too intricate for us to even begin to understand’ only opens the door that nothing we see or hear is real. So everything we think we know is in quicksand; not sure how that helps the discussion.
Actually quantum entanglement is not really generalizable to apply to everything. It's a specific quantum mechanics term. For example, the team of Chinese scientists who recently established the new distance record for teleportation relied on quantum entanglement. They didn't actually teleport a particle from one place to another like Jeff Goldblum in The Fly. 

Not to ruffle anyone's feathers, but how about liquid cables? Definitely a niche. Too early to say if it will stand the test of time?

Spent a lot of time borrowing CD's from the library 35 years ago and putting 4 albums on a L750 tape - PCM digital taping on the cheap -  still have two players gathering dust 
Re: liquid filled cables, I assume Randy means the Purist Audio Design cables. Bought two pair in the 1990’s (nicknamed "Texas Water Cables" by Stereophile).and they still sound very good. PAD is very much alive some 25 years later and continues to make and sell excellent sounding cables and power cords, albeit with different substances now inside the jacket.
