    I'm now clear why my high current amplifier works well with my low impedance Magnepan speakers. Hans told me: it delivers ship-loads (my Mom used to call it Boat-Loads) of current.
    Great video Thanks

    Driving a set 802d3 with a PrimaLuna (2 x37w) and I love it but you are 100% right the solid state I use with higher damping factor has more control over the lows. But sometimes the less control is nice, like with soft jazz..and specially at lower listening volumes.

    i have several amps some with low DF and 2 with 200 and 400 DF respectively, they are all different of course, but when i switch ported speakers and closed speakers between them the differences are very noticeable, in general low DF amps like closed cabinets and high DF like ported, this is a personal experience made by the audio stuff that I have some years ago, but as far as audio is concerned, it's all very relative.

    Tight controlled bass seems to be something of an acquired taste. I have a friend who complains that my system must have something wrong with it (bass is a little dry, but clean and extended). When a mutual friend bought some new speakers with horrible box colouration, nothing below 45 Hz, and placed so as to cause slow booming honks, it was explained to me that this is "real bass". What can you say?

    Hans would it be true the type of speaker would react differently to the amount of damping factor.Exsample horn loaded bass bin has hardly any cone movement a ported speeaker has large amount of movement. would a horn need less and ported more?or would it just depend on the impedence.but then again the encloser has a effect on the impeadence.nothing is ever simple is it!

      Horn diaphragms might generate less voltage but since the sensitivity is far higher they are also driven by far lower.current.

      Not as difficult as the 803's but they do need a powerful amplifier. The sensitivity is low (you need mare watts than on the average speaker for the same acoustic output).

  • @willbrink

    Good vid. DP, like THD, and others, became a race / selling point and thus people lead to believe that 0.002% THD would sound better than 0.004% or a DP of 500 inferior to 100DP and so forth. He states a DP above 20 (!!!) has not added benefits.

    I miss some factors in the explanation which also have an impact on damping factor and electromagnetic damping. Loudspeaker cables and the crossover network. I think the biggest impact on the damping factor however is actually the voice coil resistance itself. Heating up the voice coil is also an extra impedance, lowers the damping factor and lowers the actual electromagnetic damping. The impact is huge (and also on passive crossovers).
    Suppose you have an amplifier with an extremely high damping factor, no cable resistance and no crossover. One degree Celsius (1ºC) temperature rise gives 0.4% extra resistance (depending on the material). That brings down the damping factor to 250. One degree.
    10ºC brings down the damping factor to 25.
    100ºC brings down the damping factor to 2.5.
    And at the maximum rated power and maximum temperature of the voice coil (depending on the driver):
    200ºC brings down the damping factor to 1.25.
    250ºC brings down the damping factor to 1 (at this point the resistance is doubled, and your passive crossover is one octave off).
    300ºC brings down the damping factor to 0.83.
    I build and use a system with a total different strategy. As the electromagnetic damping is all over the place, I eliminated it all together. I use a power amplifier with a very high output impedance (a very low damping factor, essential a current source), so cables and voice coil temperature has no impact on the damping (frequency response, compression, etc). The actual damping is defined by EQ (Linkwitz transformation). As the damping, frequency response (and so on) are stable now I can very precisely control the frequency response of the driver. On top of that there is no thermal compression anymore (power compression), IM distortion is much lower (all the IM distortion by the inductance is eliminated) and there is much lower modulated noise (all the back-emf is eliminated). (SGR Audio has active loudspeakers, the Convex series, based on the same principle).
    In my opinion the damping factor is crucial for performance and stability of performance, the lower the damping factor the better 

    (an output impedance that’s at least 100 times higher than the nominal impedance of the loudspeaker/driver).
