Designed and engineered in JBL’s world-famous acoustic engineering facility in Northridge, California, the HDI-3800 is the flagship of the JBL HDI Series. This floorstanding loudspeaker features a 2 ½-way design with patented High-Definition Imaging (HDI™) waveguide technology, the patented 2410H-2 1-inch (25mm) compression driver, and triple 8-inch (200mm) 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 painted High Gloss Black, 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 intense research into the nuances of waveguide design. In search of exceptional high-frequency detail and uniform directivity for smooth in-room response, JBL engineers pioneered a design that delivers neutral frequency response both on- and off-axis, and provides a seamless transition between the high and low frequency drivers.
