Running these speakers direct from your t.v. is probably not a good idea. You might want to pick up a receiver that allows more than just a l and r output. A receiver with tv audio ins and outs would allow you to use a sub woofer as well as a center channel speaker as well as additional satellite speakers. Best buy has some excellent choices with both quality at good prices. Also, give your speakers a gradual increase of volume as you use them, this will give the speakers a chance to get used to higher volumes. Speakers need a break in time, so to speak. Usually about 250 to 400 hrs.
