A:AnswerYes. And I actually checked out the mated Vizio soundbar in the store today and the styling and sound were top peg. I'll probably get that next over the holidays as I'm using a 60 dollar logitech 5.1 setup now (that is fine, but could be fuller) and the new TV really demands a step-up in audio quality. But yeah, I think they link via bluetooth and or wifi, or direct via optical cable as far as everything I've seen.
A:AnswerPoor and "not really." The menu does have an adjustable equalizer but the built-in speakers produce low quality sound (not crackly or anything; you'd have to hear it to know what I mean.) I would definitely recommend audio be output through a receiver or stereo with optical or RCA inputs if you are looking for any measure of bass.
A:AnswerYes, you have up to two weeks. If you purchase a warranty, which is a must, if it changes the price range, they will adjust that also! The sales person, will even assist with the price matching if you ask!
