Only 3.5 high, the ZVOX Z-Base 555 home theater system can be placed beneath your flat-panel TV - so you can have surround sound without adding a lot of clutter to your room. It requires no external speakers, subwoofer or speaker wires. The 555 reproduces TV shows, music and movie soundtracks with lifelike accuracy - including crystal-clear vocals and thunderous bass. And the ZVOX Phase Cue virtual surround system delivers remarkable three-dimensional sound. The entire system-speakers, amplifier, virtual surround technology and powered subwoofer-fits into the super-slim cabinet. With only one connecting cord and a one-page owner"s manual, it is truly "plug and play." The cabinet is robustly constructed using fully-braced MDF (medium density fiberboard) - not molded plastic. Beautiful hand-lacquered high-gloss ebony end panels create a stylish look.
