EPDR more important than impedance alone
it seems to me to make sense to look at the big picture (aka EPDR) rather than a smaller one (the traditional impedance spec). Yes very true, traditional impedance specs only give half the "load" story. Nasty combined impedance and - phase angle (EPDR) loadings nearly always seem to happen in the bass where most current is needed from an amp, and that's where many amps fall down, even "if" they have huge 8 or 4ohm wattage spec, they fail miserably into these EPDR loadings.

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 |
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 |
