My SVS 25-31PCi sub is already on its way and should be here next week, and I can't wait! I have a few questions now that I'm about to be part of the SVS family. I will be running it from a Panasonic SA-XR50 receiver. - what precautions do I need to take to make sure the sub does not bottom out or get damaged. Does sub bottoming out always lead to damage? I am in an apt so I don't think I will be able to play it that loud but I'd like to know. - is there a way to calibrate the sub without using a BFD? - any tips or advice about placement or other issues is also welcome. If there have been previous discussions on this please link to them as I could not find them.
