A lot of decent reviews on this for some reason.
Yes this will increase the sound quality of your tv without the need for loads of speakers and a separate amplifier/cinema system but for the price of it, around 150 as of Dec 2011, I think you can do a lot better. My pc speakers, logitech Z4's cost me 40 and these blow this soundbar out of the water.
What you don't get with this soundbar is much bass, yes it is there but don't expect anything amazing.
Looks wise it scores highly with its gloss black finish and you get a remote control with which you wouldn't get with most pc speakers, it fits underneath the tv and has connections for attaching other equipment.
With sound bars you're better off getting one with a separate subwoofer.
