Damping Factor What happens if I put a resistor in series with the speaker?

[mp3streetparty]

Damping Factor = Z Load /Z Source
Say an Amp has 4 ohm load with D F 100

4 / 100 = 0.04 ohms output impedance of the amp.

Does the D F halve or go to below 1 if I add a 4 ohm in series with the load?
1. 8 / .04 = 50
2. 4 / 4.04 =0.990099
Just not sure which side it needs to be on.


Just to confuse the issue.
If I have 4 amps DF 100 with 4 ohms in series connected in parallel going to one 4 ohm speaker.
What happens then?

Why do you want to lower the damping factor of the amplifier? You do realize that the damping factor is already lowered an extreme amount just by connecting the speaker and amp with wire right?

In effect many tube amplifiers have the equivalent of a resistor in their output.
Bob Carver did that on some of his big power amplifiers. So that you could select a low impedance output or a tube sound output.

I just wanted to know what effect a resistor the same value as the speaker has on the damping factor?

Then for example I put 4 amps in parallel via resistors (in order not to blow them up) what does it do to the damping factor overall.

Wire has a big influence on a speaker output quality.

I'm working on an exercise in futility for something to fill my day in..

OK Cool.. Tube sounds...does anybody know if there are recordings of tube sounds anywhere I could DL to compare eg Prefer TNT AC/DC

Oh I have noticed that some onboard sound cards dont have the low end frequency response one needs..Use a name brand with lots of little capacitors on the pcb.

I'm not really sure what the end game of all this would be?

In what way?

Now the above makes sense.

He means that tube amps have a specific sound, usually because they when they distort, it is even order, which is more pleasing to the ear. They give a "warmer" sound that some prefer.

I'm thinking the damping factor is still irreverent since i'm not sure the resistors would be sufficient protection for the amps.
