June 28, 2016: Harman’s JBL has introduced its new flagship Project Everest DD67000 loudspeaker. The DD67000 features new woofers and a crossover network. Project Everest is exclusively distributed in India by ‘Meilleur by Fairdeal Electronics’.
The Project Everest DD67000 blends classic JBL design elements from the Hartsfield and Paragon loudspeakers with contemporary styling. The DD67000 retains the curved and angled surfaces of its predecessor and a flared midrange horn, complemented by the loudspeaker’s rosewood finish with the addition of a new carbon-fiber baffle trim panel and elegant rosewood and maple finishes.
The DD67000 is equipped with two of the new 1501AL-2 cast-aluminum- frame woofers, featuring a three-layer laminated cone construction comprised of an inner and outer layer of pure pulp stock with an inner foam-injection- material core. This woofer cone features low frequency with extension down to 29 Hz (-10dB anechoic). Performance is furthered by the 1501AL-2’s newly designed accordion- pleated poly/cotton surround, yielding a woofer with a fundamental resonance that is 10Hz higher than previously. Additional features include a 4-inch voice coil immersed in an Alnico 5DG magnet that is immune to temperature changes and a copper-steel- laminated top plate.

The 476Be midrange/high-frequency compression driver utilizes a 4-inch, pure-beryllium diaphragm that is formed as one-piece diamond-embossed surround and dome. The 476Be also features a 4-inch aluminum edge-wound voice coil, a rapid-flare coherent-wave phasing plug and a pure-copper- sleeved pole piece that maintains maximum magnetic gap flux. The DD67000’s 045Be-1 ultrahigh-frequency compression driver uses a 1-inch beryllium diaphragm and 2-inch neodymium magnet to produce frequency response beyond 50kHz. The driver features a new precision-cast, pure-magnesium phasing plug. Both compression drivers are mounted in JBL’s computer-optimized Bi-Radial horns that are made from the company’s SonoGlass material. The Project Everest DD67000 employs a crossover network which uses a DC bias system and is comprised of four separate circuitboards—one for each transducer—to optimize each board for each driver and its corresponding frequency range.
The DD67000’s performance can be tuned for any system and room thanks to its front- mounted control panels that enable adjustment of low-frequency and high-frequency levels and other characteristics. The JBL Project Everest DD67000 includes air-core inductors, polypropylene foil capacitors, wire-wound and metal oxide resistors used in multiples to prevent value shift during high-power operation and more.
