I have a sound bar. I'm not fooling myself. It's much better than the built-in speakers (though my soundbar has a small subwoofer, so that helps a lot). Is it equivalent to a real A/V receiver/amplifier with large speakers? Definitely not, but that setup costs a LOT more money, plus I'm limited in how much I can turn up the volume anyway because of my neighbors.

The projector thing is a no-go for many people. They cost a lot of money, the bulb inside has limited life and is very expensive (and makes a lot of heat too), but worst of all, they just aren't bright enough for many viewing environments. I would never be able to see it in my apartment, except late at night.
