Project EVEREST DD66000 CHAPTER 1 Preface JBL wishes to thank you for selecting a Project EVERE ST DD66000 loudspeaker s ystem . It represents the sum total of our research and developmental efforts in sound reproduction over the last half century. We have labored to create a loudspeaker system with no acoustical or electrical limitations whatsoeve[...]

CHAPTER 2 Legacy - the historical development of the JBL Project loudspeakers Of those few who seek perfection in sound reproduction, only a handfu l have actually achieved it. The price is always high. It is a rare occurrence indeed when an individual or group is able to triumph over the constraints of economic and technological reality just once.[...]

Project EVEREST DD66000 In this respect, Project EVEREST DD660 00 is at once the most advanced and sophisticated loudspeaker in the world today and a speaker whose technology is deeply rooted in over 6 0 years of tradition. JBL's president in 1954, Willia m Thomas, described the Hartsfield as "...the speaker system we have always wanted t[...]

Since Project Everest was introduced, sound recording and playback technology has undergone a revolution of its own. With the advent of CD, extremely demanding recorded signals had become the rule ra ther than the exception - the average source material used by the typical audio enthusiast had become superior to the best demonstration material of e[...]

Project EVEREST DD66000 As an outcome of the K2 development, a loudspeaker system with high e r sensitivity and wide r dynamic range became reality without power compression or distortion even at an extremely high drive level. The development of the Project EVEREST DD6600 0 l oudspeaker sy stem wa s started as a celebration of JBL’s 60 th Anniver[...]

CH APTER 3 The Project EVEREST DD66000 loudspeaker: a triumph in acoustics and technology The following sections describe the primary features and components of the Project EVEREST DD66000 loudspeaker system. The basic system configuration i s what JBL has historically refe rred to as an augmented 2 - way. In the 1950’s and 1960’s JBL built pri[...]

Project EVEREST DD66000 The transducers, horns an d crossover networks are housed in a visually stunning enclosure that is reminiscent of both the H artsfield and Paragon systems. The specially curved baffle provides the sidewalls for the main horn. The top and bottom horn flares are accomplished by the a tta chment of precision molded Sono G las s[...]

T RANSDUCERS The 150 1 AL Low Frequ ency Drive r See F ig u re 2 The 1501A L Low Frequency driver is very similar to the 1500A L used in the S9800 system. It incorporates a new high impedance voice coil to allow a pair of woofers to be used while still maintain ing an 8 ohm system impedance. The voice coil length has been increased to 30.5 mm (from[...]

Project EVEREST DD66000 even - order distortion components. All suspension elements are tailored for maximum mechanical displacement linearity. The cone is comprised of a special layered paper pulp matrix with proprietary Aquaplas ™ damping which offers more pistonic behavior throughout the woofer’s operating bandwidth, and controlled cone brea[...]

A high purity copper sleeve is used for the pole piece . This greatly improve s the electrical conductivity of the copper sleeve for lower coil inductance and thus greater high frequency output at 15 kHz and above. T he copper sleeved pole quickly wick s away heat generated by the coil and contributes in reduction of dynamic power compression. To c[...]

Project EVEREST DD66000 These features, when taken as a whole, create a new large format compression driver with the greatest high frequency extension, lowest distortion, smoothest response and greatest sonic detail. 045Be - 1 Ultra - High F req uency Compression Driver and Horn Like the 045Be, the 045Be - 1 uses a 25 - mm beryllium diaphragm and 5[...]

Internal Crossover Networ k The circuit topology, combined with the acoustic behavior of the 1501A L and 476Be provides a 24 dB - pe r - octave transition at 700 Hz. This is the primary crossover point of the system. Additionally, t he 045Be - 1 is turned on above 20 kHz to provide exten ded response to beyond 50 kHz. A second 1501A L woofer is use[...]

Project EVEREST DD66000 CHAPTER 4 Unpacking the Project EVEREST DD660 00 System All components of the Project EVEREST sy stem 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 P roject EVEREST syst[...]

VI . Cut tapes at the corners of the bottom cardboard (drawing VI), slide out the loudspeaker system toward you together with bottom endpads (drawing VI - 2). VII . Lift the system slightly on the right and left in turn to remove bottom endpads . VIII . Remove the protective non - wovens. VI VI - 2 VII VIII Products are shipped with round - tipped [...]

Project EVEREST DD66000 CHAPTER 5 Selecting Cable Speaker wire and interconnecting cables are an important component in any audio system. With a system such as the P roject EVEREST , they assume a new level of criticality. The P roject EVEREST loudspeaker s are internally wired with propriet ary high quality copper c able s , specially designed for[...]

CHAPTER 6 A mplifier Recommendations No single type of amplifier is specified for use with the P roject EVEREST DD66000 system. The spe akers are highly efficient and will operate adequately with an amplifier or receiver of 70 - 100 watts. Howev e r , the transient response and audio definition of a high - end system such as P roject Everest DD6600[...]

Project EVEREST DD66000 CHAPTER 7 Placement and Set - up Considerations The Project EVEREST DD66000 loudspeaker system is designed to be less affected by room acoustics than conventional imaging systems. However, it is very sensitive to overall symmetry, proximity to walls, ceilings and corners. Ideally, any listening room should contain a combinat[...]

fast and sharp bass. T he low frequency alignment feature enables placing the speakers near or even in a corner without producing a n over - abundance of bass. This corner placement ability allows optimum performance even in small rooms . Find the most suitable point by using various source materials. The Project EVEREST DD66000 requires right or l[...]

Project EVEREST DD66000 CHAPTER 8 Project EVEREST DD6 60 00 Switch Operations The EVEREST DD66000 has 2 control panels under the cover at the center bottom of the front baffle. Shorting bars or switches inside the control panel enable to switch orientation of the system and biamplifier and also to adjust woo fer and high - frequency level s . They [...]

The other system should be set to “right” and be positioned as the right speaker. HF Drive / LF Drive This allows to s witch normal drive using a set of amplifiers and bi - amp drive using 2 set[...]

Project EVEREST DD66000 HF Level This switch adjusts the attenuation applied to the 476Be (hi gh frequency or HF unit) by approximately 0.5 dB over the range of 1 , 000 Hz to about 8 , 000 Hz. The action is accomplished by trimming the main attenuation resistors. Mid - range sound becomes calm b y reducing level and b righter b y increasing level. [...]

Battery Installation The network of this system utilizes the proprietary JBL “ charge - couple method ” to activate capacitors by applying DC bias usin g battery and this eliminates unwanted distortions. Please refer to procedures below and install the supplied batteries on the battery holders. Battery Installation Procedures: 1 . Remove the co[...]
