Your neighbors may disagree, but you can never have too much power in your audio system. Why slack off on the feature that can make music and movies REALLY jump? This is a powered sub, meaning that you plug it into the wall for power, then hook it into your amplifier or receiver just like your other speakers. Its 8" woofer and built-in 120-watt amplifier will immediately make a huge, audible difference in your concerts, movies and even TV shows. Because it's magnetically shielded, you can set it near your TV without damaging the TV or you can put it off in a corner. Its low frequencies are omni-directional, so it doesn't really matter where you place it. Don't worry. You - and your neighbors - will know it's there.
