Most of the soundbars I've seen people buy are $500 or less. Yes, they like it because it's simple, but mostly because most soundbars ($100-$500) are MUCH
CHEAPER than even a good $700 pair of small active speakers.
If all soundbars cost $3K, most people would NOT buy them; they would buy $200/pr passive bookshelf + $300 AVR (total of $500). The point is that the biggest driving force is the COST. My brother spent $3,000 on a TV and $300 on a Soundbar.
People who buy
soundbars are more interested in the VIDEO than the AUDIO.
Passive speaker system can be simple. TV + AVR + 2 Towers. Just turn on the TV. Even my wife can do that. She can even sing YouTube karaoke all by herself without my help. It's THAT simple.
Bottom line is, both passive and active systems can work well, be extremely simple and cost effective. There's no need to stuff one's ideas down people's throats. Both types of systems can work. And that's all I'm going to say about this. No point going back and forth.
