The Polk SurroundBar SDA Instant Home Theater gives you a simple, clutter-free way to enjoy dynamic, three-dimensional sound with all your favorite TV shows, movies, and video games. The system includes a slender sound bar that connects to your television with just one cable, plus a separate subwoofer for punchy bass impact. The powered sub can be placed anywhere in your room, and it makes a convenient wireless connection to the sound bar — no cables to run across your floor. The SurroundBar SDA has built-in amplification, so you won't need a receiver. It also learns the volume and mute commands of your existing remote control. Please note this does not have digital optical. It is an awesome speaker but you have to use the standard red and white audio input. I bought a new tv and it does not have this connection.
