Message: <blockquote data-quote="thch" data-source="post: 1057091" data-attributes="member: 562032">damping factor -- often mispreceived.1.)  there is a maximum damping.  a length of wire to the speaker quickly limits DF to about 100, especially with low impedance speakers.2.)  the majority of driver damping will be dictated by the box and woofer's motor and not the amp.  the box models assume you use an amp with infinate DF, and thusly show that even with infinate DF, the amp cannot perfectly control the woofer.3.)  DF is given simply by Zsubwoofer / Zout.  Zout is the output impedance of the amp, and is typically less then 0.1ohm.  you are correct about the decrease in DF with lower impedance speakers.4.)  edited out -- a bit confusing and/or misleading.in conclusion, i would not buy any additional equipment.</blockquote>
