EPDR more important than impedance alone
Good stuff Buyers of expensive speakers need to "try" to understand the EPDR loading of them if they want to know if there amp/s are up to the task of driving them properly and getting the best out of the them. https://ibb.co/SDSxxBB https://ibb.co/qnwNwyF (the purple calculated epdr trace is the important one) Cheers George |
A steep phase angle can make a speaker difficult to drive. Low impedance can make a speaker difficult to drive. Neither phase angle nor impedance are steady over the frequency range of the speaker. Phase angle and impedance are not tied to each other--they vary independently. If one wants to get a better snapshot of just how hard (or easy) a speaker will be to drive, it seems to me to make sense to look at the big picture (aka EPDR) rather than a smaller one (the traditional impedance spec). |
EPDR- just what OCD audiophools need. More acronyms to worry about. Only if your not interested in trying to understand what your amp is capable of doing with what speaker. Then you get on the amplifier/speaker merry go round with your https://i.dailymail.co.uk/i/pix/scaled/2013/12/18/article-0-1A2B262D00000578-818_636x382.jpg |
