I have a question regarding damping factor ratings on amps. You see the values listed in the specs of every amp.And they are all over the place for differant ss amps. But how important are they?
As I understand, a high damping factor indicates that an amplifier will have greater control over the movement of the speaker cone especially at low frequencies (20Hz) and therfore a higher value you would think would be better. But the damping factor is also dependant on the resistance of the voice coil in the speaker and the output impedance of the amp itself. Maybe also if you have cheap speaker cable the resistance of the cables might also lower damping factor. So there are other factors.
Here is my main question, do high damping values in solid state amps indicate high levels of negative feedback design(to control distortion) by lowering the output impedance of the amp? Is this a bad design? Some have disliked the high levels of negative feedback in amps (therefore higher damping factors).
Here is the thing, I am looking at two amps. One having a damping factor of >150@20hz and the other having a value >1100@ 20 hz. Will I be able to tell the differance? Especially since the amps is only driving my fronts with everything above 80HZ (Everything below 80HZ is redirected to my subs) Is a damping factor of greater than 150 good enough? And maybe a better design?
