"A significant upgrade over basic TV speakers, but it is not a true home theater system."
The '120W surround sound' spec describes the momentary peak power of a stereo system with a subwoofer. In your home, this means sound will be louder and fuller than your TV's built-in speakers, but it is not genuine surround sound.
This product is for those on a strict budget seeking clearer dialogue and more impact from a bedroom or secondary television. The inclusion of HDMI ARC offers a simple, set-and-forget installation that integrates with your existing TV remote.
Anyone expecting a genuine surround sound experience or room-shaking bass should invest in a more capable system. The performance will not match the '5.1 surround' marketing, and power is modest.
