Sound Bars are not recommended . Surround sound is best when you have separate boxes placed apart from each other which gives the try dynamics in surrounding sound and have sounds reaching you from the strategic angles.
The Energy 5.1 Take Classic Home Theater System is an excellent Home Theater System that would do a superb job for you. Very decent sound quality and you can easily place these speakers around the room to give you full surround sound effect.
Just purchased this wonderful new TV...We want some kind of sound system ... Lots of info out there 5.1 this etc - what does it all mean - or cut to the chase and say GET A SOUND BAR (better yet - link to something on Amazon) ...Does that one bar give you "surround sound" - Looking to spend 200-300 (but less if we can)...To be used for TV/Movies - Music? Maybe...not sure of all the functionalities of the TV yet... Wired / Wireless...Thanks to all providing input on this!
