RE: Damping Factor

Posted by tweaker456 on July 25, 2020 at 09:37:53:
The issue is not fundamentally wire gauge (of the voice coil) but resistance. The resistance of the voice coil is part of the calculation of the DF along with the resistance of the speaker cable and of course gauge effects resistance. Here is wikipedia's explanation. It might be of interest to see Tre's calculation. Wonder where Tre is?? EDIT: It looks like the output impedance of the amp is likely to be about .1. 8/.1=DF of 80. 8/.5= DF of 16 This is assuming that one adds the resistance of the wire to the output impedance figure of the amp. If you put the resistance of the wire in the numerator than it would increase the DF. I wonder why it's done this way? The wire isn't part of the amp it is what the amp "sees ".
