I have a sub that came with the Cerwin-Vega AVS-632 home theater package. While I'm waiting for the Avia DVD to arrive to calibrate my speakers, I was playing with the controls on the sub and noticed something weird. There is a crossover bypass switch. OUT - if I want to control the crossover frequency on the sub. IN - if I want the receiver to control the frequency. With the switch in the OUT position, turing the frequency knob on the sub does nothing to the sound. With the switch in the IN position, turning the frequency changes the sound coming from the sub. This seems backwards to me. Maybe I should have gotten the JBL speaker package. Any thoughts on what's going on?
