Customer Review:

"A point for the fellow nerds out there: it's sometimes hard to know if true 5.1 will work if you connect the soundbar directly to the TV audio output - or if you need to plug the cable box, TiVo or Blu-Ray player directly into the sound bar. Of course it's more convenient to just use the TV output, because the soundbar can then put out sound for whatever is on the TV. But according to various internet sources: "most" televisions' optical sound output is actually converted down from 5.1 to just stereo. However, there's good news here for Vizio TV owners like me: Vizio is one of the brands of TVs that outputs true 5.1 audio from its optical output. (I even borrowed a bitstream analyzer from a coworker and verified it. Also, the soundbar lights up with a "Dolby Digital" light for about two seconds when it detects a Dolby Digital 5.1 bitstream. Pretty cool.) "

Even if you don't give 5.1 input to this system, it can create 5.1 for you through a built-in upmixer provided by audio tech company DTS. Just give it stereo and the upmixer takes care of the rest. It's not as good as real 5.1 but it makes pretty good use of all the speakers. I enjoyed this feature when playing my iPod music on the system using its Bluetooth option. Which reminds me: this system has a Bluetooth option. It makes a damn loud party sound system, which Vizio claims outputs 102 dB SPL. I verified that it will indeed put out sound at or above what psychoacousticians call the "threshold of pain"..." Read more reviews
