[QUOTE="Papermaker85, post: 6399302, member: 572595"] again frequency depandant dependant.. if i remember correctly richard clark said a dampning factor of 20 is high enought for nearly any attainable load.. you might be hearing leakage in a circuit thats only apparent at that load.. chances are you should redo you connection and check to make sure there good... i can honestly tell you that the noise your hearing is mosty likely noise from a bad ground somewhere or leakage in a circuit.. btw SD DD and RD make very good amps.. no there not top tolerance parts, but all of them use high quatitly parts... back EMF and reactance in a circuit that impeads frequency response are 2 different things, but both are frequency dependant and normally with a good design shouldn't be of concern.. like i mentioned under 6mh under 100hz you won't beable to tell the difference..
