JBL’s New HDI Series Premium Loudpeakers
by Torsten Sporn
In January of 2020, lovers of high-end loudspeakers will have a new premium line to consider for their home audio desires. JBL’s new HDI Series featuring patented High-Definition Imaging waveguides and revolutionary JBL compression driver technology showcases a wealth of JBL acoustic technologies and captivating performance to go with a contemporary and beautifully versatile style.
Led by the flagship triple 8-inch, 2.5-way HDI-3800 floorstanding loudspeaker, the range includes the triple 6.5-inch, 2.5-way HDI-3600 floorstanding loudspeaker, the 6.5-inch, 2-way HDI-1600 bookshelf loudspeaker, the quad 5.25-inch, 2.5-way HDI-4500 center channel loudspeaker, and the 12-inch, 1000Wrms HDI-1200P powered subwoofer.
The four full-range models of the HDI Series are based upon JBL’s patented 2410H-2 compression driver, benefiting from advanced research and applications from JBL Professional’s D2 range of transducers. At the core of the 2410H-2 device is a lightweight, polymer, annular diaphragm that improves high-frequency extension by reducing diaphragm mass. The V-shaped geometry of the annular diaphragm reduces breakup modes, and reduces distortion. This remarkable design is mated to JBL’s patented High-Definition Imaging (HDI™) waveguide geometry resulting in high frequencies with incredible dynamics, accurate reproduction, and a lack of power compression.
Complementing the outstanding performance of the high frequency components, each HDI full-range model benefits from equally impressive woofers including cast aluminum frames, cutting-edge motor structures, and Advanced Aluminum Matrix cones. Taking advantage of core JBL engineering techniques, the HDI woofers ensure very high output with low distortion. A 1.5-inch long-throw voice coil in conjunction with the symmetrical field motor design, flux stabilization ring, and copper shorting ring guarantee maximum output with significantly reduced distortion. Advanced Aluminum Matrix cones provide a lightweight, rigid diaphragm and eliminate breakup modes ensuring proper pistonic motion throughout the operating band. The HDI powered subwoofer model benefits from the same engineering prowess and features a high-density Poly-Plas™ cone and a 3-inch voice coil.
All HDI Series enclosures are constructed from 0.75-inch MDF with substantial internal window pane bracing that forms a rigid platform for the transducers. Enclosure tuning is a bass-reflex design via rear-firing, computer optimized tuned ports. Premium crossover components render crystalline sound while dual sets of gold-plated binding posts offer secure connections to companion amplifiers.
“The HDI Series leverages some of our most advanced JBL technologies and acoustic performance capabilities to deliver a premium music and home theater experience,” stated Jim Garrett, Senior Director, Product Strategy and Planning, HARMAN Luxury Audio. “The professional-grade compression drivers and HDI waveguides deliver incredibly realistic dynamics and lifelike imaging that makes music and movies come alive.”
While the acoustic performance of the HDI Series is outstanding, the appearance and design is equally compelling. The elegant cabinetry features a subtle radius on all side panels that blends into a larger radius to soften the corners. Flush-mount woofer trim rings, a lack of visible fasteners, and magnetically attached grilles are some of the attention to detail that results in a clean, contemporary design. The bookshelf and floorstanding models feature a gloss black plinth integrated into the base of the cabinet. The HDI-FS accessory floor stand is available for the HDI-1600 bookshelf model and includes a matching gloss black base to complement the appearance of the loudspeaker. A choice of three beautiful finishes are available on all models: painted high-gloss black, satin walnut wood veneer, and satin gray oak wood veneer.
