JBL SYNTHESIS HDI-3800

Pair of Floorstanding Speakers

Designed and engineered at JBL's world-renowned acoustic engineering facility in Northridge, California, the HDI-3800 is the flagship model of the JBL HDI Series. This floorstanding speaker features a 2 ½-way design with patented High-Definition Imaging (HDI) waveguide technology, the patented 2410H-2 1-inch (25 mm) compression driver, and three 8-inch (200 mm) "Advanced Aluminum Matrix" cone woofers for powerful dynamics and incredibly accurate sound reproduction. The HDI-3800 enclosure is heavily braced to provide a solid acoustic foundation and incorporates a bass-reflex design with dual rear-firing, computer-optimized flared ports. The sophisticated curved cabinet features a modern design finished in a choice of automotive-grade High Gloss Black paint or furniture-grade Satin Walnut or Gray Oak wood veneers. A black cloth, magnetically attached grille completes the elegant appearance.

JBL's revolutionary HDI waveguide geometry is the result of intensive research into the nuances of waveguide design. In search of exceptional high-frequency detail and uniform directivity for smooth in-room response, JBL engineers have created a design that delivers neutral frequency response both on- and off-axis, ensuring a seamless transition between high and low frequency drivers.

The JBL 2410H-2 compression driver benefits from advanced research and applications derived from JBL Professional's "D2" range of transducers. At the core of the new 2410H-2 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, eliminating time smear and reducing distortion. The result is incredible dynamics with accurate reproduction and no power compression.

The HDI woofers take advantage of JBL's core engineering techniques to ensure very high output with low distortion. The long-throw voice coil, combined with the symmetrical field motor design, flux stabilization ring, and copper shorting ring, guarantees maximum output with significantly reduced distortion. The "Advanced Aluminum Matrix" cones provide a lightweight, rigid diaphragm, eliminating breakup modes and ensuring proper pistonic motion throughout the operating band.
