I was shopping around for a home theater system and came across this site. I think it is awesome to have a forum like this. I am new to home theater system. I am looking for a decent home theater system within $1000. But I do not know what all it encompasses? I mean I already got a rear projection TV and a good DVD player. So, do I only need a receiver and speakers? What about sub-woofers? Are they needed? Lot of questions, but if you can help this newbie (who already has a TV and DVD player) setup a home theater in the realm of $1000, I will greately appreciate.
