Using patented High-Definition Imaging (HDI™) waveguide technology, a patented 1-inch (25mm) compression driver, and triple 8-inch Advanced Aluminium Matrix cone woofers, the JBL HDI 3800 produces powerful dynamics and incredibly accurate sound.
JBL’s revolutionary HDI waveguide geometry is the result of intense research into the nuances of waveguide design. 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.
