The Harman/Kardon Flow Component System has been engineered to deliver true audio luxury. The Aluminum Deep Ceramic Composite cones (D.C.C) coupled with Plus OneTM technology, provides a natural and detailed sound experience. The low-profile outboard crossover network allows the 6-1/2" 2-way component system to operate as a full 3-way system with the addition of the 3" Harman/Kardon Flow midrange. Every part of the system has been meticulously crafted to deliver visual excellence and an impeccable audio performance. The Aluminum Deep Ceramic Composite (DCC) cones provide constrained layer damping that pushes cone breakup modes outside of the passband allowing the driver to maintain ideal pistonic motion throughout its range. Pure Audio Perfection.
