Depends on how well you can tweak them individually and placement as well as other factors. I am in exactly the same situation. I live in an apt and recently got the RW. I was going to try to use them both but as much as I tried the F12 just made the RW sound bad. Sometimes I will use both for movies just to kind of fill the room a little better (the RW really doesnt need the help) but for music I turn the F12 off.
No, Mr. Bond. I expect you to die!
