Currently have the 7's as fronts. New RTi A9's are due here tomorrow. Wondering what to do with my 7's. Would the 7's work better than my FXi A6's as side surrounds? I can move my FX's to rear surrounds and give my current FXi A4 rear surrounds the boot to the bedroom. Wondering how the 7's as surrounds would compare with my current FXi A6's??
