The LG - 2.1-Channel Soundbar System with Wireless Subwoofer and Digital Amplifier - Black, Model # SH3K will connect to any TV that has an Optical Digital (Toslink) Output on it via an Optical cable connected to the Optical input on the Soundbar. With regards to if its' 300W output will be sufficient for a room of 10 x 20 feet will depend on various factors. Keep in mind that loudness decreases with distance from the speakers. The type of sound will also make a difference so what you are using the soundbar for will make a difference (i.e. Music (type of music), Movies etc.,) Depending on whether you have bare wood floors or carpeted floors will make a difference. Bare floors wood floors or tiled floors will sound more cavernous due to sound reflections and carpeted floors will sound warmer but may not sound as loud since the sound is absorbed by the carpets. Window drapes will have the same effect versus bare windows. Furniture in the room will affect the sound quality as well. 300W may be sufficient for a room that size if you sitting close to the system, but there are so many things to consider and the best way would be to actually try the Soundbar in your environment...^IFV
