JBL HDI 4500 Centre Speaker

JBL HDI 4500

Designed and engineered in JBL’s world-famous acoustic engineering facility in Northridge, California, the HDI-4500 is the anchor of a complete HDI Series surround system. This center channel 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 quadruple 5.25-inch (130mm) Advanced Aluminum Matrix cone woofers for powerful dynamics and incredibly accurate sound reproduction. The HDI-4500 enclosure is heavily braced to provide a solid acoustic foundation, and incorporates a bass reflex design with dual rear-firing, computer-optimized flared ports.

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.

The JBL 2410H-2 compression driver benefits from the advanced research and applications derived from JBL Professional’s “D2” range of transducers. At the core of the new 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, eliminating time smear and reducing distortion. The result is incredible dynamics with accurate reproduction and a lack of power compression.

HDI woofers take advantage of core JBL engineering techniques to ensure very high output with low distortion. The 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 psionic motion throughout the operating band.
