AS EASY TO CALIBRATE AS IT IS TO LISTEN TO

The YSP4000 does not use conventional speaker drivers, but is equipped with 40 individual beam drivers and two woofers. Each beam driver is precisely directed based on the auto calibration. The built-in amplifier delivers 2-watts per beam and an additional 20-watts per woofer for a system total of 120-watts. Using the multiple beam arrays to direct sound in specific directions, in addition to some fancy digital signal processing, the YSP4000 is capable of replicating a realistic 5.1 surround system from a single sound bar.

While the YSP4000 didn’t have the depth and power of my reference sound system, I thought it performed extremely well. What it might lack in maximum impact and performance it makes up for in design and function.
