Yamaha YAS-71 210W Black home cinema system

Front Surround System, 210W Yamaha's newest Air-Surround XTREME system delivers great surround sound and includes a powerful, stylish subwoofer for added dynamic bass output. Another new technology featured in the YAS-71, Extended Stereo moves the stereo image further to the sides. With an 800mm (31-1/2") wide unit, it is as if you are listening from speakers that are 2 meters (2.19 ft) apart from each other. This means that the optimum sound field in front of the unit is much wider.
