Sounds dumb but... My new Dayton 10 inch, 100 watt, Subwoofer is scheduled to arrive via UPS this coming Monday. I ordered it after seeing comments here and after returning the defective 50 watt, 10 inch, Polk subwoofer that I had bought. I can't help be somewhat paranoid and wonder if I did something nasty to the Polk, rather than it simply being defective. So, wanting to be safe with the new Dayton, is there a correct way to bring the sub-woofer on line in my system? With the Polk I hooked it up, did not hear much and then cranked its volume setting to the maximum...I heard a rattle then. I since know a bit more about my receiver's subwoofer settings. The receiver can be set to no subwoofer, min, maximum, and at various settings from 0-15. Should I be setting the receiver to minimum and increasing the volume on the Dayton, or what ?
