A:AnswerThis system uses front-firing speakers on its satellites to bounce sound off the ceiling and back down towards you to create the illusion of height. While this Vizio system does perform better than comparable soundbar systems that support Dolby Atmos content, the system doesn't sound as real as discrete down-firing speakers in a home theater setup. Home theater setups tend to come with dedicated or discrete height channels that you can screw into your ceiling, which offer the most accurate and focused soundstage performance for Dolby Atmos content.
A:AnswerI'm not sure what you mean exactly by "self-powered." My only guess is that you're asking if the speakers in this system are active vs. passive (passive speakers don't have the amplification built in, so they need to be connected to an external amplifier). This system (like most soundbars) would be considered active since it uses built-in amplification to power its speakers, making it essentially "plug-and-play."
A:AnswerThe subwoofer only has a 6 inch speaker. To get better bass, I opened up the subwoofer cabinet, disconnected the positive and negative leads, and connected them to a bigger active 10inch home theater subwoofer. The difference in bass is so much better!
