In Yamaha's CEDIA booth, their flagship surround sound bar, was audio magnificence amidst the din. In my house, the sound was big and lively.

The YSP uses 40 1-inch drivers individually powered and controlled to steer sound beams. This is based off the same tech that subs use to steer Sonar.There are two midbass speakers, too. Secondly, this unit has 2 HDMI inputs and one output, as well as the usual connections. It also upscales standard def to HD, and new to this model are concert hall modes developed from acoustics from real performance venues all over the world. There's an XM and iPod dock port, too. Calibration is done via an included microphone in less than 5 minutes. Sound is big and clear and I almost can forgo the sub. Voices were convincingly strong and even, and only above the din of the Tom Cats in the Top Gun HD-DVD pumped full volume did the speaker crackle.
