Thuderheader,
Welcome to the Shack! I have a PB-12 NSD. What, if any subwoofer did you have before? There have been those who were used to one note subwoofers who find a difference in how this and other more accurate subwoofers sound. That may play a part in your experience. What other speakers are you using? Are they set to large or small? If your receiver sends pink noise and you're using that method to set levels, you won't detect a large dip caused by wave interference with your mains or from your particular room. You may actually need to set your sub higher. If possible, use the REW on this site to do a more accurate test of your environment.
