Tech That Flopped!

"Two Bose 901 direct/relecting speakers create a sound pattern that is larger than the room itself, almost as if you were listening to 8 separate speakers." I bought the coolaid, owned these speakers and loved these speakers in the 80s. Regardless of how speakers are measured, not all people will like the same sound, and so many speakers and brands will have fans. That’s cool with me, I think it’s fun and enjoyable. BTW Omar Bose developed an almost perfect suspension system for automobiles that was never implemented. Go figure....

I think mass market appeal in technology and success is not always an indication of quality or even good sound. Magnepan comes to mind. Planar speakers are not mass market success products but they have held their own for many years and to many people.... sound fantastic. Horn speakers are still around and have many, many fans. The low power matching to tube amps produce, to a great many audiophiles, enduring great sound. In another audio technology, what about record albums? Is that an enduring mass market technology? I guess so but they were in danger of fading out of mass market favor.
The best technology does not always succeed, but perhaps the successful marketing pushes technology into favor among the masses. I think really good technology will prevail, as a general rules, even if it has to wait to be accepted. It will need some successful marketing/advertising though....
