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?

Teo should be aware of the piles of sealed box guitar speakers (most Marshalls, and many, many others), the actual extremely sophisticated bass amp rigs of varying types (some of which I own and use) utilized by professional musicians far more aware of modern technology than Teo seems to be (Aguilar…look it up), the direct to mixing board/amp mixed bass recording techniques utilized by professional sophisticated bass players, and the generally excellent bass tone of most well recorded brilliant musicians (Larry Grenadier? Avashai Cohen?) in many of the musical genres people actually carefully listen to…perhaps not in much pop or hip hop where a specific style of overload might be more appropriate, but still…mud could be part of your system, and I suggest you clean it up.
That’s quite the pile of projected suppositional strawmen.

Something nicely built up and in the end thrown in my face as if I am the shape of those things.

Bizarre. I don't know what to say except - please, don't.
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.
