KEF T301 Satellite Speaker - Black (Pair) The T301 Satellite Speaker comes standard with both the T305 and T205 Home Theater Systems, though it still makes an excellent addition to any surround sound system. As one of the world's thinnest speakers at just 1.5 inches thin, the T301 satellite speaker combines several landmark innovative driver technologies inside a stylish enclosure. T301 is designed to be mounted on the wall (hardware included), on their included desk stands, or on the T Series floor stands. The ultra-thin T301 includes two 4.5 inch double-layered mid-frequency drivers and a 1 inch aluminum tweeter, which brings you all the pleasures of true audiophile quality sound in a speaker that perfectly complements the aesthetics of the latest flat screen TVs.
