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,

E

The confusion comes from the older generic bass reflex enclosures that extended LF by adding almost random bass emphases at varying frequencies.  I had a few of these.

Change came from the application of filter theory as exemplified by Olsen, Beranek,Theile, Small and others so that tuned vented enclosures can offer controlled performance.

Semantics, I guess.
