Soundbars can be great for what they are. They make sense aesthetically, and some of them sound pretty good -- I can definitely see where they'd come into play in a secondary system, but I would never personally use one in place of my main HT/music setup, passive or powered. I think the misconception consumers have is that these systems are a one-size-fits all solution, when really they're far from it. Most customers I demo low-end soundbars for are often surprised at how "not good" many of them sound, especially with music. You can still get much better results with a cheap receiver and a decent pair of bookshelves.
