Home entertainment, not home theater room. That means open. It's about medium size. I have a projector set up, and ps3, and a few other devices, all hdmi. I have all the receivers stuff done. I just need to know what speakers to get. My couch is about 10-12 feet from the screen. I have two walls. One behind the screen, and one to the left of the couch.
When I say I plan to update over time, I mean, use what I got for about 5 years before upgrading. Yeah, not that great. I want to start off with a 5.1 and update the components as I go on. My receiver's a 7.2 so I don't necessarily have to upgrade my sub by replacing it. I could add another one. I know starting off with two good speakers and a receiver is better, but I would prefer to always have a 5.1.
