The Hartke HD series offers the bass the best of both worlds. A warm and full-bodied shade of classical cardboard film combined with a clear, polar attack on the aluminum cone. How is this possible? The patented Hydrive Hybrid Speaker Film's outer edge and suspension is traditionally a paper that produces a warm sub-register, while the aluminum structure of the inside of the film produces a clear mid-range and accurate treble. The powerful but ultra-light neodymium magnet offers 250 W of power resistance and weighs 40% less than the corresponding traditional speaker elements.
