Oh, I forgot to answer a few of your questions. -_- lol
My bedroom is 13' x 13' x 7'. I'll post a diagram of it at the bottom. (I had to wait until I had 5 posts.)
I will most definitely have EQ, however, I know only certain ones EQ the Sub. Right now, I have a Denon with Audyssey MultEQ which takes care of the Sub also, but I'm not a fan of this receiver. I would much rather switch to something else if I can find something better in the price range. Right now, I'm looking at the Pioneer VSX-1120-K/VSX-32 (I think the 32 is the elite equivalent to the 1120, right?) or the Yamaha RX-V667. Marantz and Harman receivers are too expensive so I believe these two are my only legitimate options.
Well, I hadn't originally planned on getting a Sub which is why I was looking for Towers. Honestly, though, I'm thinking for a 2.1 System that Towers + Sub would give me a far more fluid sound since the Towers will have strong bass already and the Sub will take care of the low end.
I would lose a lot without a Receiver, though, wouldn't I? lol All of the EQ tools and such as well as the ability to run all of my video and audio sources through it.
By the way, my neighbor above me is an @sshole. lol They stomp around and make ridiculous noise all day and night. I had a small set of Klipsch Promedia 2.1's for my computer and if I turned the Sub on even 1/6-1/4th of the way, dude would start banging on the floor and even came down here once at like 3 in the afternoon because he said he couldn't hear his tv for my music....One of my roommates and I were sitting here playing Call of Duty and TALKING while listening to music but in his apartment it was drowning out his tv....lol
Here is the Diagram of my Room:
