Let me preface by saying i'm no audiophile but I think that the speakers on my samsung c650 sound pretty decent. All they are missing is some bass impact on the low end. So instead of picking up a soundbar package I was thinking about trying something like a powered subwoofer. Not looking to shake the walls, just something to provide some extra oomph. Is such an idea plausible and does anyone have any examples of such a woofer that might work in conjunction with a TV's speakers?
