Page 4: Preface
Preface Thank you for selecting a Project Everest DD65000 or DD67000 loudspeaker system. These loudspeakers represent culmination of our research and developmental efforts in sound reproduction over the last half century. We have endeavored to create loudspeaker systems with no acoustical or electrical limitations whatsoever. -
Page 5: Chapter 1: Legacy
It is rare indeed when an individual or group is able to triumph over the constraints of economic and technological realities even once. At JBL, this has happened nine times. In each case, our engineers were told to build the speaker system they had always wanted to build. - Page 6 In essence, the system had its own “built-in acoustics.” In many respects, the Paragon anticipated loudspeaker developments It was in this environment that JBL set out to create its fourth and that would occur years and even decades later. This “built-in fifth Project loudspeakers, K2 S9500 and K2 S5500.

Page 8: And Technology
The basic system configuration is what JBL historically has referred to as an “augmented two-way”. In the 1950s and 1960s, JBL primarily built two-way systems with a 12-inch or 15-inch (305mm or 380mm) woofer crossed over to a large-format compression driver/ horn combination. - Page 9 Hartsfield and Paragon systems. The specially curved baffle 4-inch (100mm)-diameter flared ports are combined with the TrAnsducers changes and back EMF from the voice coil. JBL has overcome provides the sidewalls for the main high-frequency horn.

unPacking the Project everest system All components of the Project Everest system have been very carefully packed for maximum protection against damage. As with any superior audio product, it is advisable to keep the original packing materials, in case it is necessary to transport the Project Everest system. - Page 13 removinG the GriLLes 3. Remove the cardboard and packing materials. Remember to 6. Cut tapes at the corners of the bottom cardboard. 9. Remove the protective wrapping. take the accessories out from the upper endpads.

Page 14: Selecting Speaker Wire
seLecting sPeaker Wire Speaker wire and interconnecting cables are an important component in any audio system. With a system like Project Everest, they assume an increased level of importance. Project Everest loudspeakers are internally wired using high- quality oxygen-free copper wiring. The same care that was given to the selection of the loudspeakers’... -
Page 15: Amplifier Recommendations
amPLifier recommenDations No single type of amplifier is specified for use with Project Everest Loudspeaker systems. The speakers are highly efficient and will operate adequately with an amplifier or receiver of 70 – 100 watts. However, the transient response and audio definition of a high-end system such as Project Everest will expose all the inaccuracies and distortion in the electronic chain that precedes it. -
Page 16: Placement And Setup Considerations
PLacement anD setuP Project Everest loudspeaker systems are designed to be less affected • The listener should be centered in front of the speakers, and furniture by room acoustics than conventional direct-radiator systems. However, should be of an appropriate height so that when the listener is sitting, they are still sensitive to the overall symmetry of their locations relative to their ear level is about the same height as the high-frequency horn the listening position, and their proximity to walls, ceilings and corners. -
Page 17: Project Everest Adjustments
Project everest aDjustments The DD65000 and DD67000 have two control panels under the cover at the center bottom of the front baffle. Shorting bars and switches on the control panels allow you to switch orientation of the system, engage bi-amplification if desired and adjust woofer and high-frequency levels. - Page 18 hF drive/LF drive The following adjustments are made using the above procedure: sysTem orienTATion These jumper bars allow you to set the loudspeakers for normal operation (using a single stereo amplifier or pair of mono amplifiers) As described earlier, the loudspeaker’s two low-frequency drivers and bi-amp operation (using two sets of stereo amplifiers and an operate over different frequency ranges.

care anD maintenance Project Everest loudspeakers require no maintenance other than occasional dusting with a soft, dry, lint-free cotton cloth. The horns may also be wiped with a soft cloth. Treat the lacquered surface very carefully to avoid scratching the finish. To remove fingerprints and smudges, apply a small amount of diluted ammonia-free or alcohol-free neutral detergent to the cloth and gently clean the surface. -
