Kyblack76 Posted August 11, 2012 Report Share Posted August 11, 2012 (edited) Great video man, now you mentioned amplifier circuitry that battles impedance rise. What is the name of that circuitry?. Seems the amplifier would be more important in this than a box, because the amp would fight it at all frequencies right?. After watching the video it does seem unless you are a spl burp competitor its almost a waste of time to worry about impedance rise caused by the enclosure. Amplifiers have an output impedance which will controls the voltage drop on the voice coils. To have a flat voltage, this output impedance must be low. The lower, the better. This is often called "Damping Factor" I believe the RF CP has a firmware which controls a dynamic output impedance and can adjust output current in real time. I think JL Audio has what they call a Impedance control in one of thier amplifier models. Concensus seems its more for marketing, and that the RF brains are actually on to something. Again,... great shit Ed.

gally Posted August 11, 2012 Report Share Posted August 11, 2012 what does a donk board have to do with a impedance rise?
