I am just beginning to set up my first HT system. Because money is an issue right now I'm basically just adding to what I already have. My wife was given 2 Bose 901 series speakers as a gift from her father a few years ago. One of these were stolen while we were being moved so insurance is giving us another set. So now I have 3 Bose 901's with a Bose center speaker. I know there are scores of people out there that detest Bose, but like I said....I'm using what I have for now. My question is, should I try and get another 901 so that I have 4 plus the center and get a sub (if so,whats a good sub), or should I get 2 different speakers to be my surround speakers (I will still need a sub). I wouldn't be adverse to dumping the Bose for something better but they were a gift....to my wife...from her Dad...and I value my life. Thanks in Advance.
