I should add that my room is aprox 17.5x12.5ft. with the tv at one of the 12.5 ft. ends. I there is a doorway at the right rear of the room when facing the tv. so I am thinking I need small wall mounted speakers in the rear.

I am looking at buying a home theater system. Based on some research and my budget I am thinking of geting the following: Denon AVR-1804 receiver 1 RCX4 2 RBX15 2 RSX4 1 RW10 I am hoping that someone will help a beginner validate this decision or tell me why or what I should do differently. This is already a little rich for me, however, I don't want to buy something that I am going to want to upgrade in the near future. Thanks for any help!
