ZVOX has announced the release of three new Z-Base models, the most affordable members of that soundbar line, all designed to live beneath flat screen TVs. The low-end Z-Base 220 packs three full-range speakers, a subwoofer and a 35-watt amplifier in a DVD player-sized footprint for $200. The 320 measures 24 inches and will run you an extra $50. At the high-end is the Z-Base 420, a 28-incher with five speakers, a 5.25-inch subwoofer and a 45-watt amplifier. That one'll cost you $300. All three soundbars also feature the company's proprietary PhaseCue II virtual surround sound system. More info after the break.
