A:Answer Yes you can and yes they will sound better. Make sure your tv has audio output jacks. You will need a female 3.5 mm to male stereo rca jack adapter. Also you will probably need to change your audio output source in your tv setup menu from tv speakers to external speakers. For a little more money your best option is to get a sound bar with a wireless subwoofer, bluetooth , optical and a 3.5 mm aux input . You can still play your phone, tablet , ipod etc via the bluetooh or aux input. I have a lg sound bar with a wireless subwoofer and it sounds awsome, if you hear jurrasic park playing through them you would be amazed. A nice home theater surround sound system would be great also but most systems you have alot of speaker wires to run around your room.Dont get me wrong the klipsch 2.1 promedia speakers sound great but they are designed to be hooked up to a computer, or a portable media device. The lg soundbar is designed for a tv and has special sound effects and a wireless subwoofer which sounds great behind where you are sitting. A good sound bar will cost around $250 to $300 but well worth the investment in my opinion. Sound effects are a very important part of any movie you watch making it come alive. Thats why movie theaters and movie studios invest so much in the movies sound.
