Vinny,
There's a lot to dissect in your commentary. While TAD might have "blown passed" JBL in product quality...which by the way, was borne out the mind of Bart Locanthi...JBL has been a company that has always made the best products possible within budgetary constraints. Pretty remarkable to do that kind of high-end engineering when you have to do the best you can with what you've got...and still sell product to stay in business.
TAD gave Bart Locanthi a blank check to make the best transducers possible, cost no object. A dream job for a physicist/engineer. Mr. Locanthi wanted to do the same thing with JBL technology, but management at the time knew the market they were playing to and made the very smart business decision to stay the course.
1979 was a very unique time in audio history for the supply of cobalt for loudspeaker magnets. Supply was very limited due to civil war in Africa, the main source for cobalt, and became very expensive and difficult to procure. Ferrite magnets took over for AlNiCo due to necessity. The engineering team at JBL worked tirelessly to come up with a new magnetic circuit using ferrite. The result was the Symmetrical Field Geometry motor, and is actually a better performer than it's predecessor, AlNiCo. The four advantages that the AlNiCo motors have over the SFG motors are lighter weight, self shielding, harder to break, and well, AlNiCo is a rare earth element which just makes it plain sexier. That said, the SFG actually performs better...for way less cost to the end user.
The audio market has changed with demographics. We just might be in a cyclical downturn for the Millennials and GenXers while they mature and start to appreciate the merits of fine audio systems...or maybe not. We live in a very technologically disruptive time where each market segment gets sliced thinner.
We shall see. Will the acquisition of Harman by Samsung be a boon to Samsung by looking at the telematics business? Or will it have been a mistake as populations are encouraged to get out of their own cars in favor of mass transit and ride sharing?
Meanwhile, high end audio is shrinking into a cottage industry with smaller players filling the void.
