Hi all, heres my set up, Amplifier : Rotel RSX-1057 Blueray : Panasonic DMP-BD50 Monitor : Sharp LCD 42'' 1080P (I will change soon. An old Panasonic plasma 65'' is comming home for free) i dont need 4k atm. Center : Boston 404v Column : Energy Pro Series 4.5 Surround : Paradigm Monitor Series Subwoofer : Energy C8 I know my speaker arent the best set up. The surrounds feel weak but they do what they need to... I gotta put theb ass down on the surround because you can heard some plastic! Horrible!! I really like my Pro series 4.5 for music and home theather. I know the set up is not the ''perfect'' match with the Boston as center. But im building the room, parts by parts... I am trying to find better surround in 40-80$ range used. I dont need something crazy. One question i am asking my self everytime.. Should i change both of my Pro series 4.5 to a pair of Boston... Or just change the Boston center and get an Energy center arround 80-140$ used. Thanks all, i will take all your advise. Also i would like to get some tip to improve sound in my weird room. (yeah there kids toys hehe). My english arent perfect... I am mainly french speaker.
