We bought an HW-F450 to use with our 60" Samsung Smart TV. I regret having made the purchase. The sound bar unit provides bass, but essentially no treble. Higher-end frequency response is abysmal, and I have not been able to find any way to adjust it to equal the sound from the TV itself. And unfortunately, when the sound bar is activated, the sound from the TV is deactivated, which means that the sound goes from relatively clear to horribly muffled. Every time we try turning this thing on, we wind up turning it off--the sound from the TV is better.
In terms of features, what I would have hoped for was a product that could be set up and then would turn on and off with the TV--with the sound level integrated with the TV and controlled by the TV's remote. That doesn't happen with this.
The display is small and not very readable from a distance.
We have been very happy with our Samsung TVs, but this sound bar is a dud. The only reason to give it one star is to get the system to take the rating..
