Hello again fellows, and thanks again for ALL the info, I must have spent 2 weeks reading about 2 hours a day (back and forth to and from work on the train) trying to familiarize myself with as much info as I could before I started asking questions, but all I learned was that I would have to read a LOT more before I could even begin to understand this stuff!
So THANK YOU to everyone who's been so helpful!!!
Next question! I'm considering 3 possible designs, very similar but still different, please take a look at the picture below and let me know what you think.
I will be looking more accuratley into surround sound speaker placement later on, and will need to consider wall treatment as well.
