ZVOX late Tueday added new home theater speaker systems to its lineup, including the high-performance 430 and 440 sound bars along with the IncrediBase 575. All are one-bar speakers without any separate satellites or a remote subwoofer, with all drivers built into one cabinet. The 430 and 440 models use three 3.25-inch speakers and a four-inch subwoofer, with one of the speakers a devoted center channel while the other two create a wide stereo sound stage using ZVOX's own PhaseCue sound processing.
