Is it wise to put a subwoofer’s Low Pass Setting on Bypass when watching Home Theater or listening to Music? Does this maneuver result in the receiver deciding which frequencies are directed to the sub? Won’t you get the exact same result if you turn the Low Pass to your subs MAXIMUM Hz and adjust sub GAIN/Volume to your liking? Is this common practice? I am obviously totally confused here! BTW literature accompanying the RSL Speedwoofer 12S suggests initial GAIN of 50% and Low Pass BYPASS for Movies and 80 Hz for Music. Why not 80Hz for both Movies and Music? Please advise. Thank you.
