What is the best way to set these? I have a Denon 2802 with an SVS sub. Should I set the volume on the sub up and control the output via the Denon? What level should each be set at? I have the SVS 20-39 PCi with the 320W RMS amp. Currently I calibrated the sound at 0 on the Denon with the sub level up to equal the db of the other 6 speakers at 75db.
