You'll need more info for this group
Greetings....
I'm new to this also. This site is great but you need to supply more info to get a good response.
What's your budget, what's the size of the room, movies or music, TV and connectivity to it.
Keep in mind also, the speakers are the biggest hit on the budget but they are the most important aspect, and then a receiver/amp configuration to drive them.
Hope this helps some. Check out the amp and loudspeaker sections to see MANY similar posts to your own.
Happy Listening
