I have a RW-10d subwoofer in the rear corner of a room about 20'x15'. Three speakers in the ceiling in the front and 2 ceiling speakers in the back where the subwoofer is. This is my first home theatre so a virgin so to speak on what's going on. I would like to get the best settings possible but not sure on the EQ mode, Lowpass and Phase settings. I have the manual but it's still greek to me! Thank you, Sonya
