Question 1

How's the sound quality without adding a subwoofer?

Accepted Answer

I have it hooked up to a subwoofer but I usually only turn it on for music. Although there certainly is no true deep base from this sound bar without a sub woofer, I think that many users will find the amount and depth of sound from this pleasing as is.  Keep in mind, there is a reason that high end sound bars start hundreds of dollars more than this costs.  What you are getting with the Vizio SB2920-C6 is a vastly more pleasing audio than what the standard LED tv speakers can provide, and it performs well as that, but it is not to be mistaken for "audiophile" quality.

Question 2

I want to hook the sound bar up to a Samsung 50" TV. I see that the Optical cable is frequently purchased with this. Do I need one?

Accepted Answer

You do not need the Optical Cable.  I would suggest purchasing a Samsung Sound Bar.  I have a Vizio TV Set and it works absolutely fine.  I did not use the Optical Cable because the TV is hooked up to Optimum Cablevision.    You have to program the remote to your TV set.  It comes with a manual showing you how to do it.  I.  This is something you need to decide on.. I would contact  Samsung and see if it is alright.  Samsung is A very good product.  Vizio does not have the quality of Samsung..

Question 3

Does this have a Ac power cord or just the batteries?

Accepted Answer

Ac Powe cord

Question 4

Can you use the tv remote to control the sound bar?

Accepted Answer

It depends on the remote.  I'm using a comcast xr5 remote and it works to control tv and sound bar if programmed properly.   The xr2 remote and regular comcast remotes do not work with this sound bar.  The xr5 requires the xfinity X1 system and I was able to switch the xr2 remote that came with it for the xr5 for this purpose.   It took quite a bit of research to figure this out...good luck.
