KEF T205 5.1 Home Theater System - Black The T205 comes with one pair of T301 speakers to be used as front left and right channels, a pair of smaller T101 sattelite speakers, a T301c center channel speaker, and a powerful T2 subwoofer. Each T201, and the T301c, includes two 4.5 inch double-layered mid-frequency drivers and a 1 inch aluminum tweeter, while the T2 subwoofer uses one 10 inch bass driver powered by a 250 watt built-in Class-D amplifier. The T205 5.1 home theater system is perfect for those looking for a true surround sound experience without having to dig deep into their walls. In order to produce a home theater system whose deepest speaker is only 1.25 inches, we successfully redesigned our drivers while retaining that classic KEF sound clarity.
