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?

I had a time delay unit from the late 70's or early 80's. I'm thinking it was made by ADS. Help me out on this! It was early surround sound. It was a brown unit that used two speakers for rear delay. Does anyone remember this? Joe
jnovak, it was the ADS Model 10 Acoustic Dimension Synthesizer. I had one in the early 80s. Fairly effective unit for time delay effects. You could emulate a cathedral, large hall, small hall or club.
Eric, first let me say that despite what might appear to be a pattern of antagonistic responses from me to your posts, I really do look forward to your contributions and respect your opinions, whether I fully agree with them or not. :-)


Dammit.

As hwy61 had already mentioned in this thread; can one dismiss a product like Vandersteens venerable model 2 as niche’ product? I suspect that speakers like Dunlavy, Thiel and Vandersteen ( include Quad 63’s ?) have had sizable high end market shares for a considerable length of time.

Hmmm, by overall sales, how many high end speakers do you think sitting in people’s homes are "time aligned?" Vandersteen and Thiel are clearly successful brands, but even if we combine them, have they revolutionized speaker manufacturing?

Again, this is not meant to be a judgement of quality. Just overall market acceptance of the design principles. Clearly Vandersteen and Thiel have kept the lights on as well as any boutique makers can. But first order filters, time alignment and minimum baffle designs are the technology which I’m honing in on.

As a counter example, AMT drivers were a niche, which has now, post patent, exploded. All sorts of good and poor implementations are upon us. It is well past "niche" status.

Whew...Erik...buddy. I hate to say it but you are a good bit off on your statements about time-aligned speakers.

You are welcome at my place anytime. Really.

So what percentage of hi fi speakers would you say are time aligned? I'm not a Hi Fi industry wizard, but have they occupied a larger market than I know?
