N9.5R OHM - 8Color - WhiteThe most efficient driver of the lot (95dB). It plays both clean and loud. It will play deep (below 30Hz) and high (19+kHz). It could be the perfect companion to a single ended amplifier or on a boat with a digital amplifier. The midrange is smooth and detailed for the most amazing vocals. This is the state of the art for a single driver full range system.
