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,

DBX records......Only one or two had real music content and the complex approach  soon slipped into oblivion. 
Time aligned speakers a niche'? Perhaps, but I'm not so sure. While not many manufacturers apply the principles, most of the few that do or did, achieved lasting high end critical acclaim, and significant high end market success. Sadly a couple of the most successful proponents passed away, leaving voids that have yet to find replacements with the necessary skills.
