The T9 is endowed with two balanced-armature Knowles drivers: one of the industry’s largest and most powerful mid-bass drivers, and a custom-tuned, custom-ported micro tweeter. Along with a custom unified crossover, these cutting-edge components have the headroom to accommodate whatever EQ adjustments any user may desire. Nonetheless, T9 comes perfectly balanced, with a responsive and detailed sound signature that is not overly hyped or colored—so audiophiles will enjoy a fulfilling listening experience right out of the box.
