JBL manual Project EVEREST DD66000, It isnt easy, but thats the way it is done

Project EVEREST DD66000

In this respect, Project EVEREST DD66000 is at once the most advanced and sophisticated loudspeaker in the world today and a speaker whose technology is deeply rooted in over 60 years of tradition. JBL's president in 1954, Willia m Thomas, described the Hartsfield as "...the speaker system we have always wanted to build ... the finest components ever made available to serious listeners . "

He went on to describe the process behind his creation: “Most people who own and appreciate fine sound reproduction equipment look forward to the day when they will be able to assemble a system without limitation in just exactly the way they think it should be done. Periodically a manufacturer gets this same feeling ... The science of acoustics has provided us with basic

principles-available to all for achieving precision reproduction. It is only a matter of incorporating these methods into a system design, and then taking every bit of trouble necessary to build a system precisely to the design.”

"It isn't easy, but that's the way it is done . "

The Ranger-Paragon,JBL's second Project system, was the first serious attempt at a reflecting speaker system, and broke ground in the new concept of stereo imaging. Essentially two independent full-range speaker systems installed in a handsome curved cabinet nearly 9 feet (2.7 metre) long, the Paragon's enclosure was treated as an extension of its transducers. In essence, the system had its own "built -in acoustics." In many respects the Paragon anticipated loudspeaker developments that would occur years -and even decades -later. This “built-in acoustics” concept is inherited in the latest Project EVEREST DD66000.

For nearly 30 years, the Paragon remained the most acoustically viable sound system for the home. Today, along with the Hartsfield, it is still the most sought-after speaker in the world.

In 1986, JBL introduced a new Project system that retained the Paragon's overall sense of musicality while upgrading its character by incorporating three decades' worth of continuous development in every facet of its design. Its name reflected the pinnacle of achievement it represented: Project Everest. This was the original Project EVEREST DD55000.

For the first time, the rest of the sound reproduction chain - and not the loudspeaker or its transducers - would impose limits on overall system performance. Like the Paragon and Hartsfield, Project Everest was built around compression driver technology and addressed a more refined stereo image than was previously considered technically feasible.
