Hey All, I've had my SVS 20-39 PC+ for about three months now and could not be any happier with it and its performance. I've calibrated it to 85Hz according to SVS's manual and my RS meter, but I'm not sure if I'm getting the most out out the sub. My question is should I calibrate the volume down by adjusting the gain knob on the sub (it is at the 10 o'clock position now), or should I be using my receiver's bass management to turn the levels down? In other words, is there any difference at all between the following scenarios: 1.) Calibrating to 85Hz with the sub's gain at 12 o'clock (or higher) and receiver's bass management set to -10 db or . . . 2.) Calibrating to 85Hz with the sub's gain at 9 o'clock (or lower) and receiver's bass management at +2 I realize this is a rather simple question but I just can't stand wondering if I'm getting every ounce of performance out of my sub. Any response would be really helpful. Thanks.
